[quote user="darrenwm1"]You can use an iPod Touch and whatever that software is mentioned above, but a Squeezebox or Sonos will probably offer more bespoke functionality. An Apple TV would work too, but must be navigated through a TV.[/quote]Agreed. He could even go for the duet. ;-)About the use of pc/mac versus cd-player- I didn't intend to change at first. Auditioned Sennheisers hd650 with musical fidelity v3, cd player was arcam cd192. Glorious sound. First bought the senns and the headamp. Waited a little while with the cd-player as budget was tight. Thought I'd settle for a while with my mid-priced marantz cd-player....it was truly awful! So bright and fatiguing!Then tried the el-cheapo jbl audio output (external amp) from my compaq pc. This gave much better sound quality! I can tell you, it completely changed my idea of computer related music. This all got me thinking...how much better would it all sound through a separate dac? Bought one, tried it on the pc. It's so good, I'm never going back to cd-players anymore. Performance basically 70-80 % of ambience and micro detail the arcam 192 reveals. The separate dac is better in the bass department, though, with dance and bass related music. (Tighter bass) The convenience is just an extra.Edit: to your second question: tascam us-144, either connected to compaq pc or macbook pro.
