Ways to improve DAC performance???

Hello fellow A'goners,

I recently changed my system by selling my tube CD player and storing all of my CDs onto iTunes on my Macbook Pro laptop. I also subscribe to premium Spotify and really enjoy the quality of the sound.

I'm using a fairly inexpensive Ross Martin DAC, and the noise floor and detail are really excellent.

I'm new to this "music server" approach and I was wondering if there is additional software that would improve the quality of this setup.
It has to be Apple, not PC.

I've read of various programs and downloads that help, but I'm not sure if they are a substitute for a good DAC or something that can enhance a DAC's performance?

Any suggestions or advice is much appreciated, as I am a newbie in this new digital realm.

Thanks! Lincoln

Cerrot - Okay, tell us which USB converters you have auditioned in your system.

Ive heard your soundcard.

Hi fellas!
Thanks for all of the replies. My apologies for not responding sooner. I didn't realize anyone even checked in- new Agon system doesn't notify of thread responses.
Steve N- aka Augioengr: Could you please recommend a good external USB converter with master clock/power supply? I would want to keep it under $300 if possible.

And I'll try the Audirvana.
Currently I have a 2 meter Belkin usb cable- nothing fancy- but I'm still a bit skeptical about high dollar options.

Thanks to all for your input- Foster 9: I read the article on no cable too, though I confess the concept went over my head a bit.

Any other ideas are welcome. Thanks! Lincoln

Linc - There are a lot of USB converters in the $200-300 range that are all mediocre. The best of these is probably the iFi or the dragonfly.

If you want sound quality that challenges the best CD players and even vinyl, you need to spend a lot more. The upgrade power supply alone for my Off-Ramp 5 converter costs $700, and I have a long waiting list for those.

Remember, the master clock and USB interface is the most important piece of the system. It makes no sense to spend $2K on a DAC and $300 on a USB converter. This is like buying the $2K turntable and $100 cartridge. Not great. You are better off to buy the $500 turntable and put a $2K cartridge on it.

The M2Tech Hiface USB/SPDIF converter plugs directly into the USB port thus avoiding need for USB cable. They retail for around $200, often come up used on AG for about $110. Another option is the Music Fidelity V-Link.

Been through it already, Steve. I have tried too many. Yours, the berkeley, the ayer and some of the cheap ones (and they sound cheap). USB sucks and its actually finally being found out. Talk on the hardcore computer blogs talk about how USB will be phased out in a few years; within these very forums, listeners are finally comparing the mac/pc/USB/DAC to the Bryston digital player and, guess what? they hear that the bryston blows away a PC set up? why? U S B.
You engineers only embraced it because it was like a belly button. Everybody has one.
