I downloaded the Mozart/Beethoven Wind Quintets and the Albeniz Iberia discs, both in 96/24.
Unfortunately, my experience of the Wind Quintets was not as happy as MCR01's.
The first, and most obvious, impression was that they sounded extremely bright, to the point of being piercing at times. I definitely felt there was a boost in the presence band, and that made it difficult to assess the soundstage properly.
I have a couple of recordings of these works, so decided to compare them in Audition. The TRT recordings were 5-6dB louder than the others I have, so they were amplified as necessary to yield an identical integrated loudness (I listen with replay gain on, which largely negates this volume difference). Here is a frequency scan of the first movement of the Mozart Quartet with the TRT Harmonie du Soir recording in magenta and the recording by Murray Perahia and the ECO Soloists in green:
And here is a comparison with the recording by Robert Levin and AAM Chamber Ensemble (same colours):
It's quite noticeable that there's a broad lift of almost 10dB around 1kHz, and about a 5dB depression around 10kHz. This corresponds quite well with what I heard.
Obviously these are three different recordings, each with different microphone placements and recording techniques, so you would expect some differences in tonality. But since we're looking at the same piece of music here, the overall frequency curve should be largely the same, and if we compare the Perahia and Levin recordings, this is what we see:
The TRT recording is dramatically different, though, and to be honest I would, unfortunately, have difficulty living with it on a long-term basis. It's just too bright for me.
