Any opinions on the AMR Digital Processor 777 Dac?
Coxhaus, USB/SPDIF converters do make a difference, I am using Yulong U-18 with great result after trying a bunch (including Off-ramp4 with all options). The iUSB Power works on passive converters but has minimum impact on Yulong, which already ha... 
Preamp Noise with High-Efficiency Speakers
Thank you all for the very insightful suggestions. I'll do some experiment early next month. I will try removing the ground pin (on power cord) one by one, and then try a passive preamp to see if it's a gain issue. I've had a Benchmark DAC-1, even... 
Ayon Orion 2 or Prima Luna Dialogue Premium Int.?
PrimaLuna is the most reliable and easy-to-use tube amp brand. With all due respect to Ayon, I'll stay with Primaluna. The sound quality/character depends on the actual model you are looking at, but I like the fact that PrimaLuna is more on the tr... 
Class A integrated Luxman L590AX vs Accuphase e560
I am a long-time Accuphase fan, if price is not an issue I will stick with Accuphase 560 (biased). My only concern is the quality of a DAC card v.s. a dedicated DAC. Phono cards are pretty mature these days but DACs evolve every year. As an altern...

I am on my 2nd AMR DP-777 after 1.5 years of ownership, and I am still highly satisfied by its sound. Look at my 300+ audiogon feedback, and you know very few pieces stay in my system for more than a year.Well, I wish the bass of DP-777 is slightl... 
Benchmark DAC-1 Get The Most Out Of Your DAC-1
Empirical Audio Off-ramp4 (now they have Off-ramp5) is a very good asynchronous USB/SPDIF converter, and better than DAC-1's own synchronous USB, but to hear a significant difference you have to buy battery supply and other upgrades which cost you...

Is it worth to upgrade from AF 50 to AF 100?

Expect a lot of up-n-down before 500 hour mark. If you power it down and up again, give it at least 30 min to get back on the road. 
Any opinions on the AMR Digital Processor 777 Dac?
Jeffga, good to know the improvements at 900+ hrs. AMR website says 1000 hours, which is long but not as long as my ProAc Tablette Anniversary's one-year break-in. Have you compared the BNC to the AES/EBU? I don't expect any sonic difference but t...

350 hours on my DP-777 now, and the sound starts to stabilize, the tubed SPDIF input sounds best so far, the USB input is nowhere close to its own SPDIF or my Off-Ramp4 (with dual clock and battery options) connected to SPDIF. I bought a Macbook P... 
Best Integrated, period.

Any opinions on the AMR Digital Processor 777 Dac?
Fla, According to the AMR distributor, JA didn't measure all the parameters in the proper way. Plus, if you really believe in measurement, Benchmark DAC-1 has the best numbers you can get from any modern DAC. I still own my DAC-1 and believe for t... 
Any opinions on the AMR Digital Processor 777 Dac?
Jeffga, I can tell you my battery powered Off-ramp 4 still sounds better than AMR's own USB input.

Essentialaudio: Good to know "JRMC + Win 7" sounds good. I am not sure if I want to go with "JRMC + Win 7" or "Amarra + Mac mini". I am a PC person and not a Mac fan, but I like the convenience of iTunes too, does JRMC piggy back onto iTunes' inte...
