Hi! Can anyone recommend a "definitive" hi-res release of Tchaikovsky's 6th symphony? This one always gets overshadowed by 1812! From looking around on the web, I found highfidelityreview.com's review:
http://www.highfidelityreview.com/reviews/review.asp?reviewnumber=14394207
for this release. Unfortunately, the 5.1 program is in 44.1kHz/16-bit MLP.

Thats the resolution of redbook! Can someone recommend some better fidelity/performance/interpretations? Thanks! I love this symphony to death and I can't wait to hear it in glorious mlp or dsd.
I have not used the 5.1 program, but so far as the 2 channel version, I consider it a superlative performance and sound quality combination.
There is nothing wrong with 44.1/16 PCM for playback purposes. That is transparent to human ears for the purposes of musical reproduction according to established perceptual research.
If you are worred about it 44.1/16 being insufficient because of personal experiences, please note that the high-resolution versions may not be produced from the same master as the redbook version. In fact, this has been shows to be the case on some releases when the matter was investigated(you can find analysis of some albums on this site in the technical archive). In at least one case Telarc purposely changed the master of one of their SACDs vs. CD layer(Tierney Sutton, Dancing In The Dark) according to the admission of the head recording engineer at Telarc. Another factor is level-matching and mental biasing(which is subconscious, and can not be bypassed in a sighted listening test).
If you are worred about it 44.1/16 being insufficientt because of so-called expert claims, then please refer to their citations supporting that a wider bandwidth and SNR are needed -- do they provide references to scientifically valid, conclusive studies? Or do they refer to speculative(at best) whitepapers and poorly produced listening tests? Do they cite anything? I will cite studies that were carefully produced in labratory settings, that fail to demonstrate the requirement for anything exceeding 44.1kHz/16 bit digital audio:
[1][2][3][4]. I will pre-emptively cite
[5] the *only* peer-reviewed test that ever demonstrated any evidence of detection of supersonic bandwidth; but note this study was not a valid listening test(
though it did have some small portion of listening test involved, but these tests were not sufficiently documented in the paper to carry any weight), but instead a brainwave activity study(
so it is not specifically about being able to detect supersonic information on a level that one will realize, but instead showing detection via brainwaves). In a slightly more intensive listening test performed by NHK Labs
[3] in direct response to the implication that supersonic information was audible as suggested in
[5], NHK could not replicate the claims of audibility made by
[5] in labratory listening tests. It should be noted that the statistical significance of the NHK labs test was rather low(due to insufficient number of trials per sample), even though the technical aspects and methodology was otherwise excellent. But this test was extensive in comparison to the barely mentioned listening test mentioned in
[5].
