My experience

Sorry if this is an odd location for the post, I just thought I'd toss in a very basic 2c here.

Exotic components do make a difference to my ears. I've spent many many hours playing with different types of wire, and unfortunately, it can make a significant difference, though that doesn't necessarily mean the most expensive is the best. The best copper I've found is quite affordable, it's the Vampire wire OCC stuff.

I've noticed significant differences between different types of series resistors, that's where I've done the most play with non-wire parts, and the difference between the grainy, dynamically compressed crap metal films and vishay s102s is quite dramatic, if it's in a system that can resolve it.

Another dramatic difference can be achieved by using full out poly PS caps instead of electrolytics.

To my ears, and in my experience, small parts upgrades can really bring a good component to greatness.

I understand your position. It is absurb some of the component prices. Even more so when one cannot tell whether it is sonically superior. The point in question is whether these people can actually hear the differences or are they deceiving themselves, and in the process, deceiving others as well.

At least for myself there is. But it took me 7 long years to acquire this ability. And working full time on audio development at that. Before, I simply couldn't tell the difference and therefore had to rely strictly on measurements. I suppose some of us can hear differences sooner than most, others take longer, and some simply cannot make out any differences at all.

But just because I can make out differences in components does not mean I will pay 2K for some high-end speaker cable or even 50 bucks for some super caps. Though some may actually sound better, but at the prices they are asking.......I find it hard to justify. I suppose it depends really on how deep one's pockets are as well.

What I feel is important is for all of us to respect each others' views and evaluate for ourselves not just in theory but in practice.

Just my 2cents worth. Cheers.
 
Dear No Knowledge,

As far as my system goes, it is currently in a state of flux due to a burglary that deprived me of my speakers, amp, cd, dvd, cabling and about 1/4 of my cd collection.

What I lost (main part of system) was Monitor audio Silver 5's internally rewired with VdH CS12, An arcam alpha 5cd with a class a mod done to the NE5534 output chips and the output coupling caps removed,
a Sudgen Optima 140 amp.

in the past I've owned a vintage Luxman sq606, a Denon DCD500, a pair of ARM1's that i wish I'd never got rid of.

in the past i've auditioned Proac, Audionote (low end Oto SE), Magneplanar, Teac VRDS dac and transport Sugden class A and Bryston (all of which I've liked very much)

I've also auditioned monitor audio/audiolab which was a horrid combo, and a B&W801, Electrocompaniet, XLO, Meridian 800series setup which left me totally unmoved, despite being worth the cost of a small flat.

So, i'm not impressed by price, brand, technology. i like what i like.

Recently, i've been diying because the next fix (Sugden A21a) was going to cost me too much.

I'm currently building a new plinth for a Garrard 401, homebrewing a rosewood/brass unipivot tonearm, building the second iteration of an MC phono stage with better componetry after having developed it first using bog standard resistors, caps, opamps etc.

my speakers are based on Fostex FE168 sigma drivers. once you hear the coherence of no crossovers, there's no going back i think but that's my personal preference. I also prefer tight but limited bassto deep but bloated or uncontrolled bass.


To Millwood, i would say that given I have no expectations of what topology should sound better, what tube should sound better and what brand of tube should sound better then the results i provide to tube rollers (using music that i know well and are familair with in my own system) is more valid that the judgement made by someone who has a pre concieved notion of which effect they expect to hear. The tests are repeatable and are repeated until we get a good idea of the outcome.
In cases where i can't pick a difference or can't say which I prefer at all, i say so.

If you don't hear it, or don't believe it then most certainly you stand to save a substantial amount of money. I still state that this doesn't make the experiences of those who can hear the difference any less valid.

No, it doesn't. I am merely stating that what you think you hear isn't necessarily what you hear. Once subject to a more rigorous test, some of those golden ears simply fold.

I am by no means implying that you wouldn't pass the test. I am just stating that many golden ears before you had failed to pass the test, so far. and as usually, I think taking one of those tests and walking home with $10 large would be very help in alleviating your budgetary issues.

so I encourage everyone of those golden ear types to take those challenges and see if you really are as good as you think you are - not that I don't think you are good.
 
I dont know if the magnetic field Q and gravity Q have ben answered already as I got to Page 4 and had to post and go to bed. Anyway as far as I would say

Magfield = isnt very strong and the negative effect it would have on non linearising a speakers field in the gap is concerned the speakers own error is way greater then what the earth would impinge upon it. So yes it would have an affect but the proximity of another driver sharing the same box would have more effect then the earth.

Gravity = Again the effect this has is negligable with grav maybe the voice coil is pulled down (driver fixed vertically as per the norm) out of centre by a few microns then if grav was Startrekked and obliterated. Also tho the few microns grav may impose again is insignificant as the manufactures spec maybe much greater then that of how far you can expect the voice coil to deviate from the centre by.

My 0.02$ anyway.

Yes more is involved in this then the one case scenario I concocted, but especially the earths mag field, I would say other sources of magnetics would impinge a greater impact upon performance then the earth. This is just me thinking with my common sense and has no scientific backing whatsoever. If someone can come up with some reason as to abash what I have said then please go ahead, it will add to another list of esoteria in the circle that are audiophiles for special magnetic field suppressors for isolating you precious SET from the harmful effects the earth can have upon it. But it would be fun seeing if you could market the stuff:cool:
 
Well,

What I mean is that everything effect the sound and what effect it the most is the room. Everything has more or less of a sonic profile. So how could anyone be sure that it is the new fancy feedback resistor that makes the difference and not the fact, that your wife left two pillows on the sofa, some magazins, a cup of coffee or your neighbour turning his microowen on? I do belive you guys hear differences, but is it possible to know where the source to improvment is? Or do you all do blind tests with just headphones, yes how do you guys do your blind tests?

I have impression that you must spend few years more in DIYing ,then you'll not interested in this sort of conversation.

Or the opposite. I've been doing DIY audio for more than 35 years, and the longer I do it, the more I appreciate understanding the psychology and sociology behind it. A little more time running controlled listening tests and a little less time focusing on fanciful hypotheses and dithyramic descriptions of the sonic effects of moon phase would result in real progress being made.
 
Hi NoKnowledge,

Interesting thread...

You are absolutely correct in mentioning the overall system and the effect that it has on the sound. If your system is able to resolve at a high level I can promise you that you will very easily hear the differences even in a blind test. If your system is what I term "romantic" then you may not be able to hear many differences. Romantic systems are those that are usually very musical and lush. They suck you in and you just listen to the music without doing much analysis. They're great for listening but not the best for evaluating component changes...

My speakers are apogee studio grands and they are the opposite extreme. The ribbons are ruthless in their ability to resolve detail. These speakers are not at all "romantic" sounding. But, when the component chain is good and the source is good, they are magic and they sound they create grabs your attention and doesn't let go. They also make bad source material or components sound horrible...

My point is if the entire system is fixed, resolves well, and you are very used to its sound, then when you change one piece it really shows either for the better or worse.

I agree much of the hifi world is unmeasureable hype but some of it is not. I can assure you that you would be easily able to hear the differences in component changes in my system. The differences are rarely subtle. If we make a change and I can't really hear it then I lump it into the hype category...

I belong to a hifi group that does blind testing of components regardless of price at our meetings. Our fun lies in finding really good components that are not well known and cheap... This has allowed many in our group to build outstanding systems for relatively low cost (I am the only DIY guy)... I would take a very hard look at your whole system chain before I started critiquing what others are hearing... There is a reason that folks pay lots of money for this stuff in most cases...

That having been said, I don't subscribe to the WAY overpriced interconnect and speaker wire hype... You can easily duplicate the very best doing it yourself for not much money (in my experience)...

I agree with the others that you may also need to learn to listen.

Go to a pawn shop and start with a very simple receiver that is cheap and swap it in place of your current signal chain. Try to match the volume level (some of us even use a meter for this). Then analyze the difference. Try to figure out exactly where the differences are... Listen at the very top and the bottom. Play really good source material (this is very important) and use the same song on both systems. Switch back and forth several times and slowly you start to pick up on the differences. Which one of them sounds more "real"?

I would recommend also listening to something with female vocals. If your CD player will do it, I would recommend the Chesky Sara K disc entitled Hobo. Get the 24/96 version. Your speakers should completely disappear and you should easily be able to hear the room in the recording. The sound stage should be very wide (outside of your speakers) and deep (20 feet behind your speakers). This recording was made in a large room and your system should recreate this when close your eyes... This is what you're listening for...and the component changes will affect this... It's been my experience that most cheap components won't recreate much of a sound stage. Yes, the vocal my be in between the speakers but do the speakers disappear? Can you point to where the symbols are located in the drum kit? Where are the tympani's located in the room when listening to a symphony? How far back are they? Can you hear the vocalist breath in before she starts singing? Can you literally hear her lips part before her vocal comes out? How about the echo in the room of the drum stick hitting the skin on the snare? You get the idea... I can hear all of these (except the tympani's because there are none) on the Sara K disc...

I am very surprised that your wife is unable to hear differences since she is a classical musician. She may not know the terms for what she is hearing but I'm sure she can listen and tell you that "so and so just doesn't sound right or real". The object here is to get as close to "real" as possible...

This is what makes me suspicious of the resolving ability of the systems you are listening to...

Just my thoughts...

>how do we know the difference (let's noise level) between a carbon resistor and a metal film resistor isn't on a scale lower than the above example?<

I've compared the THD figures of low-distortion line preamp circuits that used carbon-film vs. metal-film resistors, but were otherwise identical. In some cases the carbon resistor measured about 30dB worse.

First I want to say one thing, if you guys had read my first post where I said that I understand the need of decent components, like metal film resistors, film caps, low noise op amps and so on. What I wondered was if it was any reason till buying this obscene expensive components and that someone could hear the difference of a single component. In no way I'm against quality stuff if I really get quality for my money.

OK Apogee

The apogee are great speaker, my father in law had some a few years ago, but they are way over my budget and they are not the easest spearkers to drive.

But I do think my wifes (the system I'm not allowed to play with) system have a bigger sound stage, even if it is a bit on the romantic side. But they sure produce music, soul and so on.
Maybee the reason is till that I don't hear the differnces is that they are musical? She loves her system, because it makes her hear the music and everything in it. We have tried to get her new speakers several times, days spent in hifi stores, weeks trying new ones at home, but nothing so far have kicked the pretty old Ohm's out.

Her system
Ohm Walsh 4X0
Musical Fidelity M3 Nu-Vista
Marantz SA-8260
AQ Coral interconnect
Speaker cable, some cheapo from the local radio store

My system
JBL K2 kloon, using the same elements and pre biased xover, but in an other box design..
:nod:
Rega planet 2000
Alternated between VLT ST-85 and a GC for mid/high over 800Hz
and Pioneer M1's for the bas until last week(wish i could afford them) so right now I'm running GC for the bas and I don't recomend it and VLT for md high.

Even if you guys think I'm deaf, I think it sounds pretty decent and most golden ears enjoys listen to it. I don't know but I think I could hear difference if someone changed a key component, but just that it would sound different, not nessasary better or worse.
But I would never be able to tell if someone changed my interconnects that is for sure.

Sorry once again if I've upset anyone, just curious and want to know things, wherefor I ask

/Magnus

PS: Guess I will do blind tests here all night, to figuring out if I'm deaf or

Holly smoke! 30db worse?

a few questions if you don't mind:

1) in absolute terms how high/low is the THD for carbon resistors? if, for example, after the 30db hit, it is still below audible levels, I don't think anyone can make an argument that they can hear that (by definition).

2) what happened to other cases where the carbon resistor didn't impair THD by 30db? why the inconsistency?

3) what is the mechanism in the carbon resistors that did the 30db damage?

Just curious.

Can you recall what sort of metal film resistors they were, and did you try to measure the difference between cheap and expensive ones (e.g. MFR4 and RC55 and up)?

The 'traditional' reasons why circuits need expensive precision resistors (high absolute accuracy, tight matching to another resistor value, low change in value with time/temperature) aren't obviously useful in, say, setting the gain in a feedback network - a 1% inaccuracy in absolute gain never hurt anyone.

Are these (or other) virtues of precision resistors measurable in an audio context?

No Knowledge, I'll ift a couple of quotes from your original post if I may.

Firstly:
"Are there any reasons for exotic components and other magic’s?"

Reasons why they work or reasons why people are willing to buy/use them?

As far as why they might work (please note that I'm not saying they all do, and many are used to provide "flavouring" if you will, in that film caps generally sound brighter and more detailed while paper in oils generally are considered to sound "darker" and "smoother") this is a fairly technical issue, steeped in science and mystery (and proprientry technologies).
I haven't the foggiest why a different dielectric film (poly prop as opposed to polyester) would sound different, one can only go by their own expereinces and the experiences of others who's ears they trust. As to why ceramic (Elnas), graphite (Black Gates), or Bamboo fibre (Technics) might make an electro cap sound different, again, I aint got the foggiest. All we's got is our ears.

As far as the second side of the question, why buy or use them, I guess it's a case of wishing, within one's budget, to get the best performance you can. Some people put resources into buying or building constant current sources for every stage, some into ultra low noise regulation, some into only valve rectification, some battery power supplies, some battery biasing, some silver foil coupling caps and black gates in the cathode cct.
Which gives "the best sound" or "the best value" is anyones guess. To some, none of it may make any audible change, to others, it's night and day, to others it's tradeoffs where gains in one aspect of the sound must be weighed against compromises intorduced elsewhere. Circuit tweaking is more of an art than a science and it's a constantly changing art at that.

Secondly:
"but I’ve never been able to hear any difference, neither have my wife and she do have golden ears."

Here we get into an issue of semantics. To have golden ears can be taken at least 3 ways.
*Firstly, that you have great hearing. I can't be stuffed reviewing the entire thread to find out if it was your wife, someone's wife was a classical musician who could detect musical details readily within the orchestra she was in.
*Secondly, that you are capable of hearing things that others cannot.
*Thirdly, (a derogatory term) used to describe a magical audio geek who can hear stuff that doesn't exist.

This is oversimplifying and to a degree all three definitions can bleed into each other in different ways.


Examples:
When I listen to a complex orchestral piece, I cannot follow the whole. I can follow individual instruments, I can follow the melody, I can follow the counterpoint but sadly (unlike a certain Mr Mozart) I am utterly incapable of listening to the lot, all together, let alone taking it all in and being able to recall any of it again at will. In this case, I do not qualify for the "orchestral wife" version of "Golden Ears".

As far as hearing things others cannot, I get both a plus and a minus guernsey here, having (when younger) been not able to pick the differences but now being capable of doing so. As I stated some time back, I truly believe that to some degree, some of this is a learned skill.

The third version, if i am to take the opinion of the naysayers out there, holds true for me. I'm one of the audio wierdo's who believe in some of (SOME OF, NOT ALL!) this stuff.

If I try something and I hear a difference (or in the case of a blind test, if someone else changes something and I hear a difference) then i hold it to be the case that there is a difference. If I can describe the difference and assign attributes to it, so much the better.

I guess, the times that I can pick the difference i'm golden eared and the times I can't I'm one of the naysayers.
BUT
If others can pick the difference at the times I can't, this doesn't make their insight any less truthful or relevant and I would hesitate to derogatorily refer to them as "golden ears".

Certainly, if none of the tweaky bits you've ever tried have made even a squeak of difference to you, you're liable to be better off financially, spend less time brooding about how you might tweak that little bit more out of the circuits abd yes, also belive us all to be stark raving bonkers.

On the other hand, if you've ever made what logic would dicate should be a small change and found a dramatic improvement, you may spend much money and time looking to increase the gains you've made even further or improve other aspects as well and find "tweaking" with boutique parts to be one of the great joys, mysteries and challenges of the DIY hobby.
