I would be interested in a review of your UA 710 now that you've had it for a while. Have you used it with an AKG414 yet? This one really has my interest...
I like it in that you can add varying amounts of creaminess to the sound or none at all. Meaning, if I am using my GT66 mic, I can run purely solid state. If I am using my other condensers, I can add a bit of tube warmth.
I miked up my guitar cabinet with a 57 and listened thru my Soundcraft, the UA710 and the Avalon 737. The differences were slightly varying levels of different characteristics. The Soundcraft sounded good - surprisingly good compared to the other two. But it had a bit of a metal bite to it. It wasn't a bad sound at all but it was like aluminum is compared to steel. Still had a sort of bark in the mid range but not obnoxious. The UA710 was like a piece of sanded aluminum where the edges are smoothed out and the blemishes start to disappear. The Avalon was more like translucent aluminum. More clarity but again the sharp edges were smoothed.
This is about the dumbest comparison I've ever come up with but that's exactly the impression I got.
I think the UA 710 is great for it's versatility. You can go from a Grace 101, no coloration kind of sound to a nice rounded tone. I never drive it until it distorts. I tried it on guitar straight into the Hi-Z input but I didn't what I got. I prefer the cream in the coffee to take the edge off approach. (Once again a dumb metaphor.)
When I get a chance, I'll likely get another to make a stereo set. Actually, I wouldn't mind having the model with the 4 x710s in it.
Before that, I think I might try to go for a Vintech 1073 clone.
