How does solo piano help you evaluate audio gear?

I attempt to tell you that as an "evaluator" for sound, that no one instrument be it a piano, guitar, oboe or human voice may by itself, hold utmost importance.

Right. And I said more than once that I was not asking the question, "Which is the *one* instrument to use for evaluation?" Read back through the thread.

When a person garnering attention here turns petulant, I’m out.

When someone responding to a thread turns petulant and leaves, I rejoice.

UPDATE:

I listened to a bunch of recordings mentioned today. The piano recordings were unbelievably revealing tools. The power of the Colom recordings and also the Schiff pushed the speakers for dynamics, subtlety, honesty of color, hall reverb, and yes --piano bench noise and the pianist breathing or moving. 

Some passages, it was clear that the hands were separated on the piano -- with the towers. The two way speakers mushed things together a bit.

In other passages, it was the piano's treble region that really brought out differences -- were they rinky-tinky highs or shimmery, ringing highs? That was a clear difference which spoke, again, in favor of the tower.

The French horn pieces were excellent, too. That is an instrument with a lot of condensed complexity -- and quirks. I can see now why it is such a test for speakers.

The more boring of the two speakers, the ribbon tower, did a far better job than the two way stand mount with these instruments. When I added the subs and dialed them in, color and space flooded in while the towers retained their honesty.

I find a great test is plugging in my own keyboards (Technics P30 stage piano and Roland fp5) and it instantly exposes any weaknesses. Have a beautiful refurbed Brinsmead (great British make) upright fettled by an excellent tuner until funds stretch to a Bosendorfer.......

I apologize if i reacted a bit rudely but your post was a bit rude also... 😁😊

You seem to be a gentleman though...

I am more wired to understand people but i also  tend to react too swiftly ..

i understand you better now and i offer to you my deepest respect...

Sincerely yours...

Your past experience is welcome here for sure....

2ndly, when any poster here becomes impatient enough or high on his horse enough to begin his response with "for fucks sake" because of inner turbulence created by an answer contrary to his pre conceptions, that acts as an antagonist to my less than perfect side.

Is it right? no. I’m as imperfect as he.

I am not wired to "turn the other cheek".
