I hope I'm posting this in the right section, if not please move it appropriatly. I'm driving myself insane here trying to complete my a/v setup and could really use some help. So this is what I currently have: Xbox 360 S | Atlona AT-HD620 | 27" iMac i7 | Razer Mamba | Drobo | Apogee Duet | Bowers and Wilkins P5 Forgive me if my setup is a little unique but the way this works is the Xbox 360's HDMI output goes into the Atlona AT-HD620, gets upscaled from 1080p to 1440p and then displays on the 27" iMac. This includes the audio too, which goes into the mini displayport aswell as the video. Now all the iMac audio goes into the Apogee Duet except for the audio from the xbox which will only play through the iMac's speakers, which bring me neatly to the problem... I really want to invest in a nice pair of speakers for listening to music. The headphones on the Apogee's DAC are nothing short of fantastic but wearing headphones all the time isn't great and also I can't play games using headphones on my current setup. There is, however, a phono output on the Atlona AT-HD620 for audio throughput but I have reservations about the quality of the DAC inside this device. Obviously the iMac has an analogue out but I know from experience It's got a fair amount of noise on it. Now for the options: 1. Buy some nice active speakers that will plug directly into the Apogee Duet and use the Phono output on the Atlona to get sound from the xbox to the speakers. This way is nice and simple but as I said before i don't know if I trust the DAC on the Atlona. 2. Buy a stereo amp and some passive speakers, run the RCA output on the Apogee into it and the Atlona output on a separate channel This setup would be okay for the Atlona because I know the dac, but it gives us the same problems with the atlona. 3. Buy an a/v amp with a digital input and a pair of passive speakers, run the optical out of the Xbox 360 into it and run the RCA output of the Apogee into a separate channel. This avoids having to trust the Atlona with my audio feed but requires more money for an a/v amp rather than a stereo one. I'm quite partial to this idea through because it leaves the dac of the xbox audio feed up to a box designed for the task. 4. Buy an a/v amp with a digital input, feed the 27" iMac optical out into the digital input, plug the Xbox into a HDMI connection on the a/v receiver and output the hdmi to the Atlona for display. This method is reasonably future proof and would also mean i could plug more than one HDMI device (ps3?) into the 27" iMac. It also means the Apogee is only having to worry about inputing instruments into my computer. However I'm not sure about the quality of optical audio from an iMac. --- So these are the ideas I have had so far, I need your input! Have you had any experience with a a/v setup close to this? Am i being stupid in thinking optical audio carries over the DAC work to the amp being a good thing? As you can see i need a little help so thank you in advance!
