Thinking about either taking a chance on the new UA 4-710d or the API A2d. The flexibility of the UA sounds excellent, conversely, everything I've ever heard about APIs are top notch. This would primarily be used on drums, though I would utilize them wherever and for whatever. For now I've just been using the pres in my FF800 for drums, and while they have been just fine, I have a chance to upgrade before the end of the year, so I wanna go for it. Having 4 channels on the UA to conceivably get a variety of tones/sounds is quite attractive to me. Of course, with the API, I only get two channels, though I'm sure they'll be great. Lastly, the UA would max out my capacity on my FF inputs, but alas, I can link in up to 4 other device, so you could argue that it would give me the ability to expand. Just thinking out loud; your feedback is well appreciated...thanks.
