I believe there is less variation in DVD-A players than SACD players. Perhaps this is because the DVD-A technology is just an extension of the mature CD PCM technology: 24 bits instead of 16 and 96KHz instead of 44.1KHz. There are more new lessons to be learned for SACD. Of course the output analog circuitry in important for all formats, and can be addressed by mods. When I upgraded my universal player the SACD performance improved but the DVD-A was not significantly changed.
The "full capability" of DVD-A does include multichannel. I will put in my usual plug for Tacet discs of classical chamber music. $29 a pop from elusivedisc.com.
