What amp for Thiel cs3.5's?


I'm looking for a SS amp for my 3.5's. I Don't have a lot of money to spend. $500 is about it (I will buy used). Do i need something that's around 200W/ch into 8ohms (must double down into 4 ohms) or should I get something a little smaller of better quality? I would really appreciate any advice.
thanks

I have a Conrad Johnson MF2500A driving my Thiel 3.6's and feel it does a great job. This amp is about 1800 to 2200 used which is out of your price range. I agree with warrenh in that you need good clean power to drive the Thiels and get the most out of them. And believe me they have alot to offer if driven correctly.You might get away with a CJ MF2250A which is about 1200 to 1500 used and puts out 125wpc.
You could get a Parasound that will put out 300wpc into 4 ohms for that money or a Rotel. Either will do the job fine and the differences are small between these and the much more expensive amps. Good Luck
I use an Aragon 8008BB to drive my Thiel 3.6's, and I've been very pleased with it. It supplies 200wpc into 8 ohms and 400wpc into 4 ohms. It is very solidly built, and it seems to be a good match for the Thiels. The sound is both full-bodied and transparent. You can probably find one used for around $1K; this is a little above your range, but it represents a lot of amp for the money.

Good luck!
I know that I'm not able to give the Thiels what they really deserve by spending around $500 on a used amp. That's why i asked if i should buy quantity or quality. both is out of the question at this point in time. the plan is to buy something to get me by for now and definitely upgrade later. I guess the subject of my original post should have been "what amp to cripple my thiels the least" :)

would a CJ sonograph SA250 provide good, clean power? it is 125W into 8ohms/250 into 4ohms.

thanks for all the help!
