Advice on Setting Up A Laptop-Based Audio System?


Hey, I'm looking to set up a workspace audio system based around my Apple Powerbook G4. I've got about 100 GB of uncompressed audio on an external hard drive. I currently have Monsoon planar speakers and matching subwoofer hooked into the laptop through the 1/8" audio out, which soundsokay, but I think I could do better.

I don't have a PC card slot in the Powerbook, so I'm limited to a USB audio connection. I'm not looking to hook this system up to my "big rig" -- it's just for my workspace. I was looking to bypass getting an amplifier, unless it's fairly small.

I was thinking of going with some powered mini-monitors and maybe some kind of adapter/DAC in between, but I'm space-constrained and not looking to spend more than say, $600 total.

Any suggestions?

I have been looking at the MiniDAC after a few people on Head-Fi actually said they preferred it to the Benchmark. I was thinking this might be what I get especially since I listen to classical music primarily and if I get a sound that is too digital/detailed I get listening fatigue. Although I have not heard the Benchmark, those who don't like it as much as some say it is a bit analytical.

Edumke, have you compared your MiniDAC to the Bel Canto or Benchmark units?

Thanks, dshea
I have only compared the MiniDAC to a Monarchy DIP and Monarchy M22c DAC. It was really hard to compare, because I only had one pair of cables, so it would take me 5 minutes to switch between DACs. No obvious difference that jumped out at me.

I talked to an Apogee tech who said he thought the MiniDAC sounded as good as some of their high end DACs.

I have a McIntosh MDA1000 coming next week. We'll see if there is any difference in the sound for 8 times the price!
I have a headroom total bithead right now, which goes out of the USB of any computer (instantly recognized as a destination for sound out in your preferences) and to some ultimate ears or powered monitors. it's more than okay and a huge improvement over the minijack out for the cans. however, I am looking into the apogee mini-dac, and the wavelength brick, for a more permanent setup with a computer that I might leave in my main system. another thing I tried is the new outlaw rr2150 receiver, which is a strong integrated amp that has a USB input. sounds pretty great for the money, but won't help you at work I guess. I would recommend checking out the total bithead.
Asio4all - computer based players should all download this - for free ! It fixes problem in window, and makes the sound smooth, like an upscale gear.

Gonglee3 - ASIO4ALL is only for S/W drivers that do not accept an ASIO plug-in. Drivers that can accept the plug-in should use ASIO plug-in, not ASIO4ALL. I have heard that ASIO4ALL is actually an ASIO emulator using Kernel streaming.
