Hi There, I have just joined here after reading about the forum in the 'Home Studio Recording' book by Rod Gervais (which has been a huge help to my new studio build) I am just putting the finishing touches to my new studio build which gives me the perfect acoustic space to mix in. I have been mixing material for 6 years on Logic 9 / Mac Pro / Saffire Pro successfully all this time with many releases doing well upon release, but now it's time to put my new acoustic space to the best use and upgrade my equipment. I need a new audio interface with 16 quality D/A converters due to wishing to delve into the analog summing route. I already have 2 good pre's so these are not so essential to me. Finally, I would really like the UA Plugs as part of this upgrade. Next year will will be performing live PA's so I also have that in mind. After reading some very helpful threads here and elsewhere I have narrowed down my choices and would love any user feedback. Products: UA Apollo Quad Audio Interface UA Quad DSP Apogee Ensemble SSl Alphalink SSL X-Desk Allen & Heath Zed R16 So to get my 16 channels of summing I can have either of these options: A&H Zed R16 & UA Quad Card (Pro: Enough cash left to buy good stereo compressor, analog EQ, easy DAW connection with bonus midi. Cons: Is sound quality compromised with the Z16 - it's reviews are superb? Large unit for live use, no live UA plugs) Alpha link, UA Quad Card & X Desk (Pro: Easy connection with X-Desk. SSL grade quality throughout Small enough desk for live PA situations. Cons: No UA plugs live, no analog EQ, only 4 ins which for now is no problem for me) UA Apollo & Apogee Ensemble linked with X desk (Pro: 16 channels in and out all superb quality converters. UA Plugs on input – great for live. Small enough desk for live PA. Cons: No analog EQ) The music I write & produce is mostly electronic edged from D&B & Dubstep to Trance & Electro but I am ever more involved with acoustic projects. I am always tracking vocalists. When I originally looked at summing, I had not considered a full console but you will notice I'm up for giving that route a try as the ZR16 is a consideration. Option 3 combines a second unit with the Apollo but I'm not sure how possible / stable this is. I'm waiting on a reply from UA directly about connecting via Adat. I look forward to being a part of the forum. Thanks in advance for any help and advice.
