TONE

"I've always considered starting a thread in which we list some recordings that we believe accurately convey the true sound of musical instruments, but like so many threads, they just turn into arguments and lectures, so I dropped the idea".

@chayro you had a good topic idea . Some threads on this forum do manage to remain  interesting,  informative and respectful. 
In regard to your recording industry experience, did  the processing affect all music genres equally or were some more egregious than others? Pop/Rock versus Jazz/classical for instance.

Make your own music recordings! Borrow or rent a pair of good mics and a reel-to-reel recorder, and ask a musician friend (you do have them, right?) if you can record a live performance. Once the tape is rolling, listen intently to the music and the sound. Then listen to the recording at home, comparing the sound you heard with the sound your system is producing.

Another great thing to record is the human voice. We are all very familiar with that sound, and any "vowel" coloration (as J. Gordon Holt put it) will be glaringly obvious. WARNING: Most loudspeakers fail this demanding test. The QUAD ESL (introduced in 1957!) excelled in reproducing singing voices, setting a standard few other speakers to this day can match.

If you are new to live recording, you may need to take a few stabs at it before you seem to have captured the sound fairly accurately. The catch-22 is that the only way to evaluate the tape is to listen to it on a system, the very thing you are trying to determine the tonal accuracy of!

If that sounds like more than you want to take on, use recordings known for having life-like tonal characteristics. Known superior recordings in that regard are those on the Water Lily Records. Try A Meeting On The River, featuring the guitar playing of Ry Cooder.

• OK, thx
  

please list any recording you consider to tonally accurate, and whether it is LP or digital

For piano this one is one of the best to test piano tone playing...
And anyway also one of the best interpretation of Chopin Nocturnes by Hans Moravec...

(beware : the youtube file so good it is does not replace the original recording)

Piano is the only instrument on par with voices to test the rendering of an audio system...

Any amplified music is useless for that....Anyway with a great audio system able to communicate all " hues" of sound color,  some amplified instruments or electronic music  often  seems more a seasoning than a real meal....

You are right for what you say about this Quad speakers...

But i will add something: all other speakers need more help from tuning room acoustic controls and they could reach some new level.... For sure each type of speakers are different, but no speakers are perfect on ALL acoustic factors even Quad...

We never listen to speakers, we listen to acoustically controlled or uncontrolled room/speakers....

But some speakers speak to us better than others in the same room....but adapt the acoustical settings of the room for each type speaker in particular and even our taste could change or be less affirmative...

No speakers beat the room says a great acoustician....

But i will repeat what you just said: QUAD is one of the greatest speaker ever designed...Precisely for the reason you said already....
