... upgraded system gear has shed some light on the initial question posted here. Having owned a Sony NS999ES with signature truth modifications by Modwright for about 6 months now has defintely shed some light on the benefits of SACD technology ... it is clear to me now that SACD is better than redbook CD playback. Performers are more palpable, bass goes deeper and has better articulation, highs have more extension, etc ... SACD does take you to the venue of the actual recording! (playing both formats through the same player). But you need to spend some money on a good mid-fi to hi-fi SACD player to reap the rewards. I also own an Audio Aero Capitole MKII SE Cd player which is very musical and has outstanding resolution. But SACD playback on the modified Sony player gets awfully close to the performance of the Capitole (for 1/4 of the price).
As far as the sound of the Volodos' recording goes I can tell you for sure it will sound better in SACD format on a good SACD player but I suspect that the poor quality sound you are getting in cd playback may be related to the sound engineering involved (i.e. equipment, mastering ... these are not always the same and can have a profound impact on the final outcome) ... hence even the SACD playback may not sound too good. Have you ever considered taking your hybrid CD to a high-end audio store and trying it out there in both formats? ... that may be the best way to tell.
