I have now been using the Decade in a reference Analog and Digital system, and do not understand the sound those complaining about it are getting.
I have found the sound full, detailed and neutral. Sometimes the bass is abit 'soft', deep, big, bold but blurred (that is in comparison to the analog system, no digital system I have used is any better). It compares, remarkably, very well with the analog in character as well and general quality, sounding in general remarkably similar, any difference are due to the limitations of CD.
The system consists of Krell MDA300 Monoblocs powering big Martin Logans. The analog is Mitchell Orbe, SME V, Ortofon Jubilee. Digital transport is actually the Sony DVP-7700 DVD player, and before you scoff, it was ranked second only to a Mark Levinson CD transport by Stereophile. Cabling is all Goertz pure Silver.
