Getting good sound from MacBook via DAC.


Hello everyone,

I decided to go down the digital path and picked up a Bryston BDA-2.  I hooked up an Audioquest USB 2 cable from my MacBook to the BDA-2  to play music from my Itunes and it sounds awful.  What am I doing wrong?  I tried playing with the sampling rates thru the MacBooks Audio Midi set-up but no help there. it sounds compressed, over extended bass, lack of detail and soundstage, just plain awful.  

Ive been using the DAC with my Simaudio CD player with excellent results. I also have a WADIA 177 hooked thru the DAC for my IPod which sounds surprising good. I like the idea of using the MacBook and was thinking about getting a dedicated Mac Mini for music files.

Do an experiment. Take a MAC Mini, Mac Book or PC, download Pure Music, Amarra, Audirvana Plus, Bit Perfect. Pick your track, load them all up with the track at the same place, and A/B switch play the track. Use the same DAC.

You will hear the differences. Why? Isn't digital digital? And that difference is without considering all the colouration the PC/MAC is adding along the way with noisey power supplies, audio filters etc.

This has driven me to develop a 'no compromise' media server. It's nearly there. Ground up best practice design and build - software - hardware. Bit-perfect codec, lossless digital signal processing, ultra high spec DAC and power supplies.

It will satisfy me, because I'll know exactly what I've got from source to destination. Whether it becomes a product for others remains to be seen.

From that test I did three years ago, I concluded my MAC Mini setup would always be sub-optimal.
