I'm afraid that it is a kind of off-topic because my material is not for a classical music and it involves no Grimm.
However, I hope it would be interesting for some audiences.
Just yesterday, Mr. Takada of MIXER'S LAB (
MIXER'S LAB - Engineers - Hideo Takada - MIXER'S LAB) presented a set of reference sources especially recorded for comparison of sound quality resulted from differences in resolutions and formats. His demo was given in a technical presentation of "Sound Salon and Conference" held by Japan Audio Society in Tokyo.
For the comparison purpose, he mastered several Jazz trio sessions played by Toma(Sax) and Mami(Pf) with Sato(Perc) in Victor Studio using Avid Pro Tools and three Merging Pyramix/HAPI devices that digitized one identical analog mixing console stereo output in parallel. (All mixing was done in analog and the stereo output was recorded in Pro Tools and Pyramix/HAPI. No post editing was applied on those DAWs in principle.)
A benchmark is 44.1 kHz/16 bit PCM digitized by Pro Tools. "High-resolution" test samples are mainly digitized by Pyramix/HAPI.
One of the comparison sets was "the same format: DSD with sampling rate variations: 2.8, 5.6, 11.2" on Pyramix/HAPI. We could perceive clear differences of sound quality among them. It was a very interesting experience for me. His appropriate comments were added after each demo for listening comparison.
A playback system employed in his presentation consisted of foobar2000 on MacBook, Accuphase DC-950 (ES9038PRO based DAC), TAD amplifier and TAD speakers.
Other comparison sets were;
variations in typical types: 44.1 kHz/16 bit PCM(Pro Tools), 384 kHz/32 bit PCM(Pyramix/HAPI), 11.2 MHz DSD(Pyramix/HAPI)
the same format : PCM, bit depth: 24 bit and variations in sampling rate: 96, 192, 384 kHz
the same sampling rate: 192 kHz and variations in bit depth: 16, 24, 32 bit
(Those sources in the variation were obtained not by down conversion but by individual setting difference on three HAPI devices)
The sources will be released from "Stereo Sound" publisher as a package of DVDs with CD and distributed on-line through e-Onkyo.
