Music Reproduction Systems - what are we trying to achieve?

Wow! hornets' nest ......
Just bought a 96k/24bit recording of Vaughn Williams Symphony 2 1920 version
see: Vaughan Williams: A London Symphony & other works - CDA68190 - Ralph Vaughan Williams (1872-1958) - Hyperion Records - MP3 and Lossless downloads
and played it through my new DSP and amplifiers. Plenty of bass, transparent top end - sound levels seem to be similar to listening in a concert hall. Better than CD quality.
What is missing from the recording/playback is the quality of tone, particularly in the top strings. This could be anywhere in the playback system, but probably the speakers (Eikona 1). But ... string tone is not consistent in live orchestras - I just know it ain't right whatever orchestra is on the recording.
That doesn't stop me from enjoying the symphony, and as I am unlikely to hear the 1920 edition live then I just get happier as the playback system improves.
Insufficient bass is usually the biggest disappointment. As long as I can tell flute from oboe from clarinet then the top end is just fine.
Does this help BasicHIFI1 to answer his original question? or just add more mud?

Andy.. i read your response woth interest. It dawns on me that your qualifiers are subjective and dependent on your hearing which will be different from others as they'll be to others as well.

I appreciate your descriptions and relate to a vinyl 2 box collection i was given of the classical greats but my turntable is midrange at best. A technics manual arm unit with anti skip and speed adjust.

Speakers are again technics and not particularly specialiswd in the higher frequency end.

Hi TNT... 'faithful cues' aren't measurable and therefore they're subjective.

Sound pressure is most certainly connected with dB which is volume. Given that sound is transmitted in pressure longitudinal waves where the amplitude of that pressure wave coincides woth the volume we hear.

So to remain objective we need to be talking about qualified measurables.. rhat is to say a measurables along with cinditions of measurenent that effect it... for example bB at 1 meter from the speaker along the axis outwards from the cone centre or the frequency limit at a particular dB level.

All this sounds very clinical and lacks the gut feeling but thats the only way we can agree on what we perceive.

I would like to know what R2R tapes produce in terms od frequency and signal to noise ratio... at least as indicative figures.

How do you purchase music in R2R ? Do they send the reels in the post and are they transportable like that ?

how many 4 minute songs can you fit on a R2R tape and how easy is it to change tapes.

All these go into the enjoyment because convenience also counts.

Of course the ritual of threading the tape can have its own degree of enjoyment... akin to cleaning the dust spwcs of a record and gently setting the needle down.

Its a subjective level of enjoyment. .but id be interested to see how much we can measure the R2R performance.

"Tactical cues" = vibrations e.g. in your seat and very measurable. I think you complicate things.

Cassette tapes suck. They don't use enough tape. Tape sheds particles which losses high freqs. They also slowly demagnetized.
Have you tried the newer ones ?

They were developed past the time CDs became popular.

They're highly portable of course but advances in their players yielded increases in their reproduction and even convenience.

I'd imagine that a faster moving medium like R2R woul have a higher tendency to remove material from the tape but thats just a gut feeling.

Ah i hadnt connected that but isnt that a feature of the speaker or indeed transducer placement.

I have transducers bolted to the seat which produces vibrations lower than the 20hz threshold of hearing.

Brilliant for tactile engagement...

Unfortunately measurment is the only way to truly agree on what we're talking of as all the rest is waffle...subjective.

The devices we are usung to communicate are worldwide and despite all the differences of users particulars and indeed techical architecture... they communicate freely because of internationally agreed standards of measurement and protocols.

This way each participant knows exactly what is neant by a phrase or utterance.

Indeed measurement and standards are extremely important when comparing different technical devices for faithful reproduction otherwise opinions are like ears... everone has a pair.
 
When it comes to psychoacoustics very little is measurable with instruments
I hadn't noticed psychoacoustics before.. looking at the wiki it seems that the listening experience varies between people listening to the exact same equipment from the exact same position in exactly the same room...oweing to the biilogical differences between the listners themselves..including psychology, ear pathway, brain function and more.

But this would make any discussion of the qualities of a particular equipment for listening to music as totally subjective and therefore lacking verasity for the purpose of comparison.

If equipment is being compared... then a basic scientific (psychoacoustics is a scientific discipline as wiki announces) principle is to keep all factors the same and only change one.

This principle is so central to science that it forms the first and key message to secondary school students..even before they do experiments themselves to learn about and indeed compare aspects of the world we live in.

So... I feel very uneasy about comparing equipment like cassette or R2R within the parameters of an arbitrary listener who undoubtably differs in their listening biology to me.
 
It's Dolby SR that is the superior tape noise reduction system, not "S". And it IS superior, but it also is quite expensive, really meant to be used with professional open reel-to-reel tape recorders.
I'm aware of that and that it doesnt apply for the reasons you stated.

SR is meant for music professionals and largely unaffordable for the average home listener.
S was the best tradeoff on price for quality that could be made.

So S is the way to go becauae the vast majority of people who enjoy music aren't professional recording artists.

Here's one for all of us: physiological changes while listening to music:

http://jass.neuro.wisc.edu/2013/01/Lab%20Report%20602_5%20final%20submission.pdf

It is true that sound had to be felt as well as heard: here is some information, but how do we do this at low frequencies? Maybe some sort of a massage chair type of device?

There may be other tricks into increasing the tactile feeling of your bass. As was mentioned before, it could be that simply having your mouth open may make a difference in how you feel sound. Keeping the room warm may help as well, since one experiment found the skin to be more sensitive to vibrations at 86°F than at 59°F. Body fat has also been shown to dampen vibration and obstruct its propagation throughout the body, so shedding some body fat may help to get a more visceral feeling from your sound system. One precise way to easily bump up the ‘feeling’ of your bass is to boost certain narrow bands in the bass region instead of the entire frequency range. As was noted in our testing, 50-63 Hz seemed to carry a very potent effect on the chest region, so giving that frequency range a boost may give your system an extra kick.

All quite relevant.

My experience with cassettes is that I have to listen to my favorite songs all over again, it's totally different in digital format because I can hear the high end better, especially the high hat changes the character of the song completely, not to mention the punchier bottom end.
Yep cds did make it sound clearer but cassetts have moved on since then so that now the average person would not know if a cd was playing on a hi fi or indeed a cassette.

Recall that hearing starts to degrade from the age of 12.

Yes its true that music is the one stimulus that 'lights up' more parts of the brain than any other interaction.
 
Andy.. i read your response woth interest. It dawns on me that your qualifiers are subjective and dependent on your hearing which will be different from others as they'll be to others as well.
"Plenty of bass" = frequency response
"transparent top end" = distortion, transient and harmonic
"quality of tone, particularly in the top strings" = any of: distortion as above; frequency response; or phase anomalies

I still don't think it is only a matter of tone curve. Faithful tactile cues and actual sound pressure is needed for optimal fidelity.//
Wholeheartedly agree. Fidelity and hence enjoyment. As I read that I heard an organ note - somewhere at the bottom of the pedal board, maybe 30Hz - at a level that made me stop reading and just be happy for a second.

Music Reproduction Systems - what are we trying to achieve? was the original poster's question. My answer is: getting as near as possible to sitting in the best seats of concert hall, cathedral or wherever.

Over many decades I have discovered that is a difficult but worthwhile task because "I am unlikely to hear the 1920 edition [ of Vaughan Williams London Symphony ] live".

As one of my neighbours says 'I need to listen live about once a week to feel right.' That's probably not subjective either.

I can't give you figures, but any trick used to enhance cassette can be used for R2R - but with the advantage that you are already starting from a much better position. That is why R2R was used for decades as the mastering and archive medium. People only used cassettes for demo tapes and music distribution - apart from a few pirate recordings.

You seem very keen on cassette. Do you have a commercial interest? You seem very reluctant to accept that R2R (which I guess you have never seen or experienced) is simply better. Higher speed, wider tracks, thicker tape, more oxide - R2R with no tricks almost matches cassette with all tricks in use.

If its not thick enough then the higher frequencies get theortled by the BASS notes.

Im sorry I don’t agree on this. I’m using Duelund 16 awg single run for my ML Odyssey & there’s no deficiency of lag of bass on any heavy music that I play.
 
For me I’ll be very happy if my system can mimic whats all in the recordings. One can never replicate live from recordings. Just too many variables invovled . Assuming that you can come close then it can only be in one recording why, different venues, mic, acoustic enviroment, equipment etc etc. What’s really important to me is getting correct timbre of instruments, over tones, decay & naturalness. As diyers, we all know that it’s easier said then done.

I have no commercial interest.
I'm not a recording professional therefore i have little knowledge of R2R and from the sound of it neither do you apart from anecdotal.

I can accept that R2R is reputed to be of very good quality... wgat i am pressing though is that because CDs halted peoples interest in cassettes, few are aware of just how good they became in both versatility and quality.

Im not shooting down R2R so please dont be offended but i am reminding people tgat cassettes resurgence in recent years is due to a late acceptance that analog forms of music reproduction carry with them a certain charm and now a higher quality than they had uaed all those years before digital.

Rather than just relying on a memory of times gone by... im enticing people to take a look and a listen to the cassette format on a decent deck that was produced after the CD took over.

With a possible 11 hours of continuous custom recorded tape play and the quality of dolby S and other frequency curve technologies like FLEX.. the cassette becomes a very good choice for the home hifi enthusiast. Im not dwnying R2R is reputed to be very good on quality.
