Computer Audio Setup


Realy wanting to get a computer setup. Im using a PS audio pwd with bridge into tube amp and merlins vsm speakers. Ive been feeding sonos into the pwd but the sonos limitations are my current issue. I love sonos for my whole house audio but not for high end stereo. I purchased a nas to put all my cds on but feel id rather have a computer based audio system. So how should I proceed? I have an imac thats two floors above my stereo so direct connection is out. Can i stream with higher rez from sites like mog or rhapsody using a computer than my current sonos setup?

Steve,

......If you want the best SQ possible, then get an async USB converter with HDMI I2S to your PWD.......

Offramp 5 is the only such device soon to be on the market as far is I know.

James,

Another thought. If you get the MKII upgrade on the PWD, you will get more bang for the buck in terms of improved SQ per $$$ than anything else you can do. You will also get an asynch USB input, so you can do "computer based audio", probably 90% of the quality of the I2S input. A MKII over USB is definitely going to sound better than a MKI using I2S.
So with the upgraded pwd I can go usb from my computer into the pwd for streaming? Control of the computer, say imac, with ipad or iphone?
You can already do that with the MKI as well. Problem is with the MKI the non I2S inputs are inferior to the I2S, and USB even more so than S/PDIF because it is synchronous.

The MKII implements the lens technology on all inputs and upgrads USB to asynchronous. So on the MKII the non I2S and I2S inputs are much closer. I personally moved from the bridge to AES/EBU a week ago (for different reasons) and the difference is very very small. You can read up on the PS audio site forum about impressions on USB versus I2S.

Getting the MKII upgrade and going USB into the PWD will be your best bang for the buck upgrade. You can insert an offramp 5 into the chain in the future if this turns out to be a material upgrade over USB direct and you're willing to spend the extra $$$.
And for music sever simply use something like JRiver on PC or Pure music on Mac. Plenty bi-directional controller apps running on iDevice available.
Edorr I really apprecitae your input. What I'm really wanting to do is use my pwd to stream from the internet or download HD tracks. So if I use a mac mini I could control the system with my ipad and go directly into the pwd using usb? Could it stream from MOG like this as well? Sorry for all the questions. I'm new to all this.
