I agree that the Brick is a more versatile unit, but the UA has MUCH more character in its sound. IN fact, I really don't find the 610 very similar to the Brick. The Brick has more of a slow soft warm sound where the 610 seems faster, and much more aggressive sounding. I personally love the UA preamps, but I certainly agree that the brick would be a little more "user friendly". The UA does definately change quite a bit when paired with an 1176 because you can use the 1176 to really change the way the UA sounds with careful attack and release times to make it sound warmer and softer. The Brick however can never really be made to sound fast and aggressive. I guess if you look at it that way, the UA may actually be more versatile, but thats only if you have the right additional outboard to create that chain.
