Jh2os:
I own a Thule IA60bSE integrated amp (balanced version) that I purchased used on Agon about a year ago. It is a very good unit in my opinion, with extremely excellent detail, PRAT and bass. I found it very enjoyable to listen to. I was frequently impressed by its ability to resolve the inividual words in songs. On quite a few instances I found myself thinking "so thats what's being said" on songs that I had heard many times before. The only real downside was that I thought it a bit underpowered (75 WPC on my SE version) for my tastes. My son is using it now in his system and he is also very satisfied with its performance (even though he is a tube-sound man). So, overall on a 1 to 10 scale I would rate it an 8.5 in the under $1,000 (used) catagory. At the <$700 price these have been selling for used on Agon, I think they are a real bargain. BTW - my Thule only has preamp out - no preamp ins. I tried the preamp out, but found the sound to be nothing special. Hope this helps. Feel free to email me with any specific questions I might help you with.
