Well, I've had the 2250 for a while now and think its time to share some thoughts.
The unit itself: Very clean looking piece, not flashy or lit up with a ton of signal indicator lights (which I like). All hookups are very solid and setting it up was easy!
Setup: I must admit at first I was completely unimpressed, but this however was my fault completely. Thanks to some extremely helpful people on the forum I figured out that I was supposed to re-run Audyssey and once that was done it became the daylight and dark difference I had been looking for as far as sound!!
Sound: As mentioned in the title and my sig, I have the amp hooked to a pair of RTi12s. I knew right off the bat that these things were lacking something after I hooked them up to an entry-level AVR @ 80wpc. It was all I could afford at the time and it worked. I will say though that the sound was far and away better than the Sony HTiB system I had come from!!
I'll share what I've noticed and attempt to explain it. First, I've never noticed my speakers being 'bright' so whether its a 'warmer' sound, I can not say. The only thing I can describe is that it sounds transparent and by that I mean it sounds like it did coming out of the Onk, but with way more authority! Details throughout the sound range were good coming from the Onk but are even better through the Parasound, I can actually hear the guy in the band plucking the bass guitar for instance. Highs are clear but not harsh at all and mids are fuller if you get what I mean. On to the bass department which is one of my favorite things. That said, I do NOT like over done bass (like trunk rattling which is very common here) but I do like to 'feel' it. The lows are so much better now! It actually fills the room like you'd expect with a tower thats so large. It will punch hard and quick!! I can see why some have said that a sub may not be required with good amplification, but of course for the HT aspect I will definately invest in a sub later on. I do like that my 12s can now be run at full range even with a sub to help fill the room with bass except in only the lowest freqs. Both with movies and music I am EXTREMELY pleased with the effect the 2250 has had on my listening experience!! My towers now sound like they look...BIG! When taking the volume to upper levels, the 2250 and the 12s will effortlessly go to unbearable levels and not even begin to sweat!
A couple of things to keep in mind. One is I bought this (like everything in my setup really) unheard/untested, just going on recommendations from the folks here and wasn't disappointed!! Two, if there are any questions about this setup please feel free to ask! I completely realize I'm no audio scholar and there are probably areas I haven't thought to address that would be very informative! Thanks again to all who helped and answered questions and threads during this process!!
