Any opinions on the AMR Digital Processor 777 Dac?


I am wondering what users are thinking of this dac and if they have compared it to similarly priced units. I haven't seen much information or any professional reviews at this point and I am intrigued by it's functionality.

Ok, I can report that with probably 350 hours on the preamp section that the anomoly (I observed) of making the music seem somehow smaller than that of my MFA preamps or the Pure Music used as the pre has completely evaporated. The difference between PM used as the attenuator is much closer to the sound of the AMR using it's own line stage. I still think PM has the advantage at this point as the sound is a little more tonally dense. The MFA units are just better but the entry level Copper Classic at the time was $3K so I would say the AMR is in good company. I could understand if someone drove their amps direct. I still need about another 100 to 150 hours on the pre section before I am sure. The transparency of the linestage is as good as anything I have heard at ANY price. It is just when it comes to the density of tone at this point that I would say some may prefer a stand-alone pre.., but it is not done breaking in and I am just reporting as I go... sorta like a ships log LOL!!!

Have a good wknd, back to listening the music David Garrett for now.
Strange -- When I play 16/44.1 redbook CD ripped into apple lossless format in iTunes (Windows XP), the USB-connected DP-777 automatically goes to "96/96 organic". This happens even if I put a redbook CD in the CD-Rom and play it directly through iTune. I really want it to do to "44/44 BitPerfect" mode using classic DAC, but it won't. Anything from my PC/iTune is "96/96". Are there any settings I need to change?
Just tried going direct to the amps (no preamp). I like this better. All the detail / dynamics / soundstage and tonality and better focus. Plus the volume level is more than adequate. Just seems cleaner w/o the usual "thinness" that typically occurs when going DAC direct to amps. Bass is fabulous. I didn't realize how good this DAC truly is until trying this setup. Best DAC I have ever owned (and I have owned a bunch). A true bargain at full $5k price.
I also tried DAC direct, and still prefer a high-end analog preamp, which adds density, weight and scale. I admit the volume control inside the DP-777 is very good, and some Asian audio forum says it's as good as US$3000 preamps, but not beyond. AMR is smart enough to implement an analog volume instead of digital, which I always find disappointing even at the level of Wadia/Weiss/Accuphase. Impedance matching is another thing, if the output impedance of the DP-777 and the input impedance of your power amp matches (>20x difference), and your cable has low capacitance, then you have a better chance to do without a preamp.
Ok, I now have right at 500 hours on the preamp section and I will say that the built in preamp sounds exactly the same as Pure Music used as the volume control which is to say world class. I preferred Pure Music as the attenuator over the Allnic 3000 (the unit with the optional larger output transformers)and the Bat Rex (yes these were in my home in my system). I would say that you would have to shop carefully and spend about right around $7K to equal or beat it. Obviously the Allnic and the Bat cost more that $7k which is why I said you would have to shop carefully.

Neither of those units could compete with PM on transparency or dynamics and as I stated the AMR and PM are indistinguishable. The guys at AMR do their homework and it does take 500 hours before the linestage is run in. In all fairness, the MFA Copper Classic has routinely been compared to active preamps that cost $10K and up so that was not a fair comparison (one reviewer stated that you would need to spend $80K on an active t obeat the Classic but that was some years ago and things move on :). I will say that the linestage is good to the point that if one has not dropped serious money on a pre...I would fully run it in and then audition a preamp if you still think you are missing something. I agree with Jeffga., best dac I have ever heard...and like him I have heard and owned a BUNCH.

I would say the built in linestage is better than most active preamps I have listened to recently with the exception of the Concert Fidelity ($20k) and the ARC Ref 40 ($24K)... that's good company :) YMMV
