MVP881 has 24 bit DACs.
MVP891 has only 4 Sabre 32 bit DACs
UD9004 and A1UDCI share 5 AKM 32 bit DACs:
Currently no other than these two in the world have 2 channels per 32 bit DAC in 7.1 RCA configuration.
MVP891 looks like a toy inside:
Now observe what happens with the caps on balanced board on the right, the ferrite rings around
the wiring looms, the grounding on the tray, and the shielded transformer:
After reading the whole thread and auditioning a lot more here is what I believe:
1. Anyone getting this player in 2013 for video or to send audio DSD/PCM/DTS-HD via HDMI
will underutilise it in a major way.
2. This is the world's best combination analog 7.1 single ended and balanced stereo BD-Audio,
SACD, and HDCD/DVD-Audio ie high resolution disc player. Mated with a processor in bypass
mode and a neutral preamplifier with good interconns in a treated room it takes you way up there.
3. Superior to the A1UDCI in balanced stereo performance, it is a reference stereo
I love it, I am in audio Heaven, literally. Now I have to find me an Audio Research MP1, multichannel balanced preamp:)
