Any opinions on the AMR Digital Processor 777 Dac?

Hi Audiofun, I played around it with again last night. I agree with you; in Preamp mode (both 0 or 6db gain), it's deleterious. The loss is much less detectable when in buffer mode, but here I preferred 0db to 6db. I also agree the Digital Antidote feature is not really my cup of tea and that the 3D feature is pretty neat. So I think we're on the same page, except for me, going from balanced to single-ended is too much of a net loss. I may wait for the iTube mini.

I'm no E.E. but I still don't quite get why switching the orientation of the wallwart will make any difference -- I mean, it's converting AC so electrically, how can it matter?

The polarity issue would take way more time to get into and explain than I have :) Let your ears be the judge, try it oriented in both positions and ponder what you hear :)

Just so you know I am not one of those people as it relates to high end who believes everything can be explained. FYI, I have no idea why some power cords sound better into my SP10MK3's power supply than others ??? well, ok.., I have some ideas ...

@Audiofun: by magnetic cables I mean those that I have in my main system: High Fidelity Cables.

@Loftarasa: it makes a difference if you swap the hot and the neutral when you turn the walwart. Even fuses have a direction! Read about the after market fuses on this and other forums. As I mentioned many times, upgrading stock fuses yield, after dedicated lines and audiophile wall sockets, the highest return.

Back to the topic: anyone have the SE upgrade installed?

Loftarasa: I agree with everything you've stated :)
