How to get good dynamics in phono stage

But I do not own a technics, rotel or NAD. I sold my NAD 1020 30 years ago and I'm not about to go out buying things just to work out if you are making sense or horribly confused. Sorry, but if you think you are onto something, record it and put it up for all of us to hear.
 
Always in the forums there are daring and disoriented people. If you want to be right. well, have it I will not follow this thread. It has been populated by intransigent people. What was a concern on my part has been used to discharge their grudges. Greetings and listen to what you want
 
So when asked to put up you throw toys out? Fair enough, but no one is any the closer to converting your words into anything audibly meaningful. I have no interest in being right, I have an interest in understanding. Words are poor at this. And talk is cheap.

I think the objective was not to corner the guy in to putting up a defense. If you can’t help without having all the information “fully and objectively defined” then it should have been obvious from the first post this isn’t the thread for it.

I don't know.
The model I like are the Era Gold and the Reflex. They are possibly "better" than my current tube phonostage from what I heard in the store demo.

I recall we did extensive comparison with the audio research reference CD8 or 9, cant remember, cd player and an older dac/transports.

The audio research phono, imo doesn't sound better than the Graham Slee. This is just my opinion. I just like very much the sound of vinyl with the Graham Slee which I don't own.
 
I found the thread on the other forum if I may copy the link here for diy's as a start. I am not the only one liking this phono it seems. It is definitely 'faster' sounding than my tube4hifi phono, or my old stereo discrete phono.

Again on the GSlee : It is not a thin cheap sounding phono, details are amazing and realism, sound is thick, spacious, exact, and very dynamic, feet tapping.

Vinyl Asylum

@DF96: If I based my opinions on the vast majority of undergraduate text books and the handful of books by "audio" publishers I've come across, and almost all audio technical publications I have read including data sheets. I would probably be agreeing with you.
As a physicist it is difficult for me to believe that something as simple as a phono preamp can exhibit non-physical behaviour, or point the way to new physics. You have the advantage of not being limited in this way, so you can believe anything you choose to believe.

Different cables sound different.
Properly constructed and properly used audio cables wired between competently engineered sources and loads cannot sound different, except in the imagination of the listener. Bad cables used with bad equipment can sound different - typically such items are either DIY or quite expensive.

Posts 65 & 66 I consider muddled thinking.
Interesting. I thought they brought some much-needed clarity to the thread.

I would encourage folks to trust their own hearing and common sense when making judgments about...err...a music reproduction system.
No!! All your ears can do is tell you whether you like the sound; they are quite poor at telling you whether it is a faithful reproduction.

Would not this result in decreased dynamics?
It depends on the PSU and the music. If the PSU has small caps and a big choke and is poorly damped in the subsonic region then the phase shift in the envelope signal could mean that you end up boosting loud passages and vice versa.

And yet the mastering engineer who created the source material did just that.... used his/her ears to get what pleases them.
You may be confusing music production with music reproduction.

Why then why in the home is it so sacrilege to tailor something to your personal preferences?
It isn't sacrilege. It isn't hi-fi, either. It is a perfectly respectable aim; the only problem comes when people confuse it with hi-fi and try to claim that their preferred distortion is somehow more faithful to the original.

adason said:
Wrong fidelity, for instance too much negative feedback applied to minimize distortion, while neglecting other parameters...low slew rate or terrible intermodulation, will be boring and sterile.
Neglecting other parameters is bad engineering, which does not lead to hi-fi. In most cases NFB reduces intermodulation.

Here you go: "If you want recorded music to sound good or like live music - you are wrong. That is not fidelity."
I have seen people on here say that they prefer their system to live music. Such people are not interested in hi-fi.

Good grief Dave, hasn't that old saw lost its teeth yet? You've cut thru so many posts with that saw (and some SET grease) that it must be slick as ice.
Repetition does not render something true - although some appear to hope that it does. However, repetition does not render something false. As the opposite of my view is frequently expressed, either explicitly or implicitly, I see no problem in simply restating what I believe. My experience in other walks of life is that if I stop protesting about something people form the false impression that I have changed my mind.

But the problem is that 'dynamics' is not clearly defined at all and there is no common reference point. An audible example would help us all to a common ground that the English language cannot achieve.

For example. When a 100 strong choir kicks off on 'Zadok the priest' THAT is dynamic live. Most top 40 pop is compressed to nothing and is NOT dynamic.

I could just as easily start a thread saying I need more flooby from my phono stage and people would be just as wise to my requirements as to the OP here.
 
Shrug. I like transamps for MM phono. I am in a select group of odd people who follow this route. The group is currently 5 people. I will not claim any audible benefits, just the happiness of bypassing all the pain of correct capacitive loading of the cartridge in return for a new set of problems 🙂.
 
If you listen to music "live" you realize that it has a dynamism. That the strong is strong and the soft is softer.

This is true. You would get serious issues with your neighbours if your home gear would reproduce the whole dynamic range. Even today it's difficult if not impossible to reproduce the whole range of sound nature is capable of. Vinyl is especially far from it.
So what you can do about it is 1) choose a range you want to reproduce, say 35 to 104 dB, 2) compress the musical content withín that range, if you have louder/softer musical information. This is always done, including those subjectivly 'dynamic' Decca SXL gems from the 60ies. Rock and Pop is much narrower, even without the so-called loudness-war.

All you can do is tricking the human hearing into feeling that sense of dynamic, and that is what competent sound engineers do, if that's their goal (as on these Deccas).
 
I have built several stages of DIY phono, some published in DIYAUDIO.
But I always have the doubt that is what gives good dynamics to a preamplifier.
I have passive phono preamps; assets; mixed
Some I like their sound but they do not have good dynamics and vice versa.

You seem to be saying that you don't like the sound of "good dynamics", is that correct? What is it about dynamics that you would call "good"? Why do you not like that sound?

Can you give some examples of phono stages that you built whose sound you liked but which lacked good dynamics? Can you give some examples of phono stages you have built that had good dynamics but whose sound you did not like? What was it about the sound that you did not like, besides the good dynamics? How else did they differ sonically from those which sounded good?

Did you find any correlation between circuit topology and good dynamics?

In all of them I use the same power source (50 watts and ultra-fast diodes); and the rest of the audio system is the same

OK that's good, you kept the power supply the same. Is your psu regulated? Have you tried different power supplies while keeping the amplifier the same? It is possible that what you are calling dynamics is related to PSRR, in which case changing the power supply might change the dynamics.
