Studio set up

For low-latency playback/recording you will need an external audio device. If you want to use a decent condenser mic (and you will if you're even halfway serious) the audio device will need 48v phantom power.

There are many possibilities. A web store such as Audiomidi.com is a good place to start looking. Check for system and software compatibility, then search the internet to learn about real-world results from actual users.

 

I couldn't speak on the quality of the converters on that (or any, really) unit. That's a peculiar one as it uses a 12AX7 tube in the input preamp. Most low cost units don't. Be aware that the quality of your input signal could be highly dependent on the quality and condition of the tube (they wear out a lot).

I would shy away from that unit because of the tube, really.

The output signal quality probably won't differ much from unit to unit in the low price range. Most likely any of them will sound better than the built-in sound on the Mac.

 

I've been using a Focusrite Saffire LE firewire device for a few years now and it's been pretty good.

AKG has been around for years and the reputation is great. You'll probably be happy with that one. Be aware that those condenser mics will pick up every sound in the room (air conditioning, computer fans etc)! But that's the way it goes when you want a good recording.

Best to read reviews from real users on both the Focusrite and the AKG.

 

That's right. You should download the driver installer from the website so that you'll have the latest release. Refer to the user guide for audio routing.

If your receiver's line ins are anything else but 1/4" you'll have an adapter situation as the Focusrite's lines out are 1/4".
