Any opinions on the AMR Digital Processor 777 Dac?
Karmakuma, I will personally choose AMR DP777 over NAD M51. To me the NAD makes more Hi-Fi sense, the AMR makes more musical sense.More specifically, if you love big bass the NAD will do better. But the AMR's naturalness and delicacy in midrange i... 
Any opinions on the AMR Digital Processor 777 Dac?
I have tried a bunch of separate USB/SPDIF converters before the AMR DP-777, including really expensive ones from Off-ramp with all possible options and modifications. Each sounds different but none presented a significant upgrade to running USB d... 
Unison Research Simply Italy or Primaluna Dialogue
Any Simply Italy owners here? 
Recommendation for SS amp for biamping
I use two Arcam P38 power amps to bi-amp. Great results! 
New Musical Fidelity M8 pre - anyone heard this
I have a Musical Fidelity M8Pre driving a variety of power amps but not the matching M8700. The low output impedance of the M8Pre makes it easily compatible with most power amps and the sound quality is among the best solid state preamps I've hear... 
External DAC For Oppo 105 At What Cost?
Mitch, I've owned the stock Oppo 105 and found its sound acceptable but not stellar. If you have CD7 you probably will be disappointed by a stock 105. Adding an external DAC will get you computer audio capability, but the 105 is not a great red bo... 
Preamp Noise with High-Efficiency Speakers
Wow, so much fight after just one day! George and Charles, we've already known you are big fans of passive pre or source-direct, but at the end of the day, some of us will turn on an active preamp and some will go preamp-less. Who gets more fun ou... 
Preamp Noise with High-Efficiency Speakers
Yes, I did try preamp-less and preamped options between the DP-777 and Cary 300SE. I prefer the preamped sound, being more ripe, full-bodied, and solid. In comparison the preamp-less sounds a little cardboardy and less 3D, the difference is not as... 
Preamp Noise with High-Efficiency Speakers
Finally got a noise-free pre/pwr combo! Audio Mirror T-61 preamp + Cary 300SE monoblocks. I don't know why but this combo is free of noise/buzz/hiss. Sounds wonderful too! The best I've heard with Avantgarde Duo.Substituting either pre or pwr with... 
Preamp Noise with High-Efficiency Speakers
After almost a month the buzz remains with any preamp, and luckily I can still enjoy music running source-direct. The buzz is audible both above and below 140 Hz, I know this because my Avantgarde Duo Classic speakers have active sub crossed over ... 
Preamp Noise with High-Efficiency Speakers
Atmasphere, you are right, I'd call it a buzz, not hiss. 
Preamp Noise with High-Efficiency Speakers
Well, guys, this thread just gained another dimension. I am a firm believer of well-designed active preamps after trying a few passive ones. I do not exclude the possibility of passives work better in other systems, and in return I hope the suppor... 
Preamp Noise with High-Efficiency Speakers
Wow, I did not know my thread can attract so many responses in days! It looks like noise is more attractive than music.Georgelofi, I currently do exactly what you say: set the input impedance at max (57k Ohm on RCA) and run DP-777 directly. I norm... 
Preamp Noise with High-Efficiency Speakers
Whart and Triode: I may have to go through the lengthy process like yours to eventually get rid of hum/noise. I was thinking about Granite Audio Ground Zero yesterday.Georgelofi and Atmasphere: There are pluses and minuses using an active preamp, ... 
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...
