Logitech Duet, doesn't need a DAC, but it surely benefits from one, requires either a direct connection to your laptop or a wireless connection in your house. Wadia iPod doc, does need a DAC.
Personally, I like the Duet, I have mine going into an excellent Upconverter (DCS) and then to a DAC (DCS) and the performance is terrific. But just straight in, especially into a mid-fi system is pretty good too.
Thanks for the great advise, guys. I'll check into the Bel Canto USB Link as I'm happy with the sound of the DAC 2. I have to buy another ext. hard drive so I'll discuss the Airport Express with the Apple Store.
Any one have a suggestion for a DAC (I'd like to to buy used to stay in that 400-600 buck range) with a USB port?
Depending on what type of firewire port you have you can also use a Focusrite Saffire or Saffire LE. This way you can use firewire into the unit and then use the spdif output into your dac. Another nice thing is you can also use it as a dac and plug it into a system that you're using when you DJ as it has the 1/4 jacks.
i have to agree with ophitoxaemia, i just upgraded my duet to a transporter and cannot be happier. i have to thank richlane, wherever he is, as i did not think it would be much of an upgrade since i was only using the digital out. his posts in the forum detailing his experiences convinced me to give it a try and it has taken my system to the next level...
I use a "HagUsb" USB-to-S/PDIF Converter. I use USB out of my Mac Mini, into the converter, then digital coaxial into my DAC. I also can use at toslink cable. It's designed for Mac. Both of the above methods will get your MacBook connected to your DAC then it's into you system.
A computer server has many way to get to music. I watch music videos on Youtube, Internet radio with iTunes and insert concert DVD's into the Mac's drive and watch while it plays through my main rig. I can also rip all audio output to my hard drive. Lot of options.
the dac 3 has a usb input but it is inferior to the other inputs. if you have a dac 2 already, get an airport express, a good jitter remover (monarchy, genesis, and others), and hook up the jitter device with a toslink from the AE or your macs toslink port, then use a coax from the jitter to the dac2.
