Sherlock Holmes needs clues


I have determined by listening to many different solo piano CDs that something unpleasant is happening consistently across all CDs whenever the piano plays in the octave between about 500-1000Hz. The beautiful warm, natural piano sound becomes somewhat thin and tinny, as though the piano needs to be voiced. Both above and below this octave, the piano sounds warm and natural. I would like to isolate the component (or resonance, or room interaction) at fault.

I plan to play Sherlock Holmes a bit - but would appreciate any thoughts people might have to assist with my learning curve.

Subaruguru, glad you spoke up here since I know you have the same CDP I do.

The Nautilus 805s have a 6.5 inch Kevlar mid-range driver. Note that the phenomenon I am referring to occurred on the Magnepan 3.6 as well, in a totally different room driven by different electronics.

I moved my speakers around quite a bit to no avail.

I do not mean to spend people out on this problem, but I do appreciate the interest.

Judit, clipping of the amps usually makes drivers to produce "farting" sounds.
Exuse my friench:^)
Not enough information, that's my diagnosis, Watson!

Since I don't happen to have the CDs you mentioned, can't do
a comparison. It could be just about anything. The first
thing to consider is two identical components that are in both systems that you listened to.

Or, that the pianos recorded happen to have this particularity?

Try some ESL headphones for a good listen?
