AMR DP-777, what am I missing ?

There are a lot of people here who love this DAC, I purchased one (used) based on the many glowing reviews, but feel like this DAC falls short.
To be sure it bested (by not a lot) my Wavelength Cosecant (better imaging and bass) but I still prefer my modest analog setup (Rega RP6, Shelter 500).

I am sure my digital front-end is not super tuned: IMac, audirvana, no-name USB cable to DAC. But before I spend more money I would love some advice from the good folks in this forum on how I can make this $5000 retail DAC at least come close to my modest analog setup that cost much less retail without spending too much coin.

Do I need to invest in a music server, or maybe a USB to SPDIF, or better USB cable or all of the above.

Rest of my system.
Coincident Line stage
Coincident Dragon mk2 monoblocks
Verity Parsifal Encore speakers.

Thanks.

There are some obvious basics required. Quality isolation and power conditioning for your digital. (And I do the same for analog.) Heed the efforts of Wadia and Esoteric with respect to power supplies and assume similar effectiveness for Spectral digital and Alpha.Different digital components, and power supplies, discharge and/or have varying degrees of sensitivity to line noise. Briefly, if you don't address these items you will never know what any particular component or your system is capable of. "Sound Application" is an outright steal used and supremely effective. "Equitech" provides exc isolation via their patented process of achieving finely balanced (noise killing) transformers. Be prepared to enter a different realm of musical enjoyment :-) . Have fun.

The usb cable is extremely important. Try a Wireworld Platinum usb cable. I was surprised at the difference. My 2 cents.

Douglas, Elsneb

It would certainly make me a very happy camper if a simple USB cable solved my problems.
I am surprised with all the talk about USB Power supplies, SPDIF converters with clocks in them in the other threads that you think they harm the sound.

I will be posting my experiments as I perform them in this thread so maybe it will useful for someone else in the future.

step 1: replace imac with a mac mini that has a SSD and more RAM.
step 2: try a good USB cable, maybe wireworld platinum.
.....
Lets see if that works, before I try out specialized music servers or usb converters.

Williewonka,

Looks like the USB cable you mentioned is sold out.
Any ideas on how to get a cable like this elsewhere.

Thanks

Essrand - even though the available amount says "0" the advertisement still seems to be active.

Try contacting the seller - Doukmall and ask them if they will be getting more.

I don't know of anyone else that sells these

However there are alternatives - like the Aqvox
http://www.aqvox.de/usb-power_en.html

There are a couple of other brands but they are very expensive - Acoustic Revive is one - iFi Audio Gemini is another

That's about it - other that DIY

I hope you are successful :-)
