[quote user="al7478"]ok, cheers. im just confused by the mention of active speakers, as im not usin them. Anyway, i may have to rethink, as im not sure ive room for the beresford. i was expecting a much smaller unit. im under very tight storage constraints im afraid. ill perhaps go with something like the m-audio audiophile usb sound card, but im having a tough time deciding, as you can tell.[/quote]
I know you're not using active speakers, and never said you did. I used the example of active speakers to reinforce a point and avoid confusion and be clear that the soundcard wouldn't be doing the main amplification; looking back at your post I originally thought you had mentioned some other stuff about op-amps and stuff but it isn't there now so maybe I was mistaken, and never mind, we've other more pressing issues, like... the fact that the Beresford isn't that big. It might look like it, but it's not a full-width hifi unit: it's only about a couple of inches wider than the m-audio!! Check the specs, lol.
(Only use the manufacturer's site this time... like with the prices, some other site probably has it listed as ten-times bigger or something...)
The m-audio will do the job, and has digital inputs and outputs unlike some in that price range. Another alternative is the Emu 0202... you don't get the extra digital I/O, but I've seen it rather cheaper, you get nice 192kHz convertors and a decent mic. pre-amp which will be useful if it turns out you ever do need to record something. It has its own low-jitter clock, headphone amp looks promising, it's bus-powered (where I think the m-audio uses an external supply) and I think the Emu is USB 2.0 compared to USB 1 for the m-audio, though this can work both ways...
In fact, I'm thinking of getting the Emu, (the Emu's bigger brother has optical and coax digital I/O, but it's twice the price... I fancy getting the little one as cheap way of adding good sound quality to a notebook with hopefully an acceptable headphone amp thrown in), though the m-audio may be preferable for you. I've seen the Emu for 65 quid, and the m-audio for 82, both at Dolphin Music. Interestingly, there's another option that had passed me by: the Behringer U-control. Small, simple, only goes up to 48kHz, but it doesn't need a separate power-supply and is only 23 quid. Looks a handy little thing, if not on a par with the others. Especially handy for a notebook. Even manages an optical out unlike the Emu.
