Hello, I want to setup an audio system when I get a refreshed mac-pro, the audio mostly for just personal use. I enjoy listening to music and have taken a college course on audio editing, used pro-tools, etc.. but was for an elective, so i'm not really into the audio technicalities so much but am a perfectionist by nature and really like high quality audio thats crisp and clean. Which brings me to the point, Which speaker set should I purchase for my use? I'm not sure how a studio reference monitor would be best and tweak the software mixer or should I get a more "consumer" oriented monitor like the M-Audio AV 40 ? Some thoughts M-Audio StudioPro 3 ($80) M-Audio Studiophile DX4 ($150) M-Audio BX5a , little over budget ($266) M-Audio AV 40 ($155) And then the audio card, I have an 24bit Audigy 2 on my old PC and it trumps my macbook pro internal soundcard by quite a bit, a lot crisper, and obviously more powerful. Made my cheap creative speakers sound great with DVD-Audio samples. From what I can pull up the Audigy cant and wont be supported in OS X so I was wondering how the on board Mac-Pro sound is compared to that? Would I just run a minijack to TRS cable to the speakers or is there a Toslink to RCA converter that would make a big difference? (M-Audio has an $80 one but kinda expensive for what I need) Also quick question, the AV 40 mentions it accepts balanced 1/4" TRS plugs...this means theres no ring on the plug and uses separate plugs for left and right channels correct?
