Thiel CS3.6 and Aragon 8008BB combo?

The load of the speakers will certainly not be a problem for this amp. It has a very solid power supply indicated by doubling down into 4 ohms. This is a powerful amp!
You got the question wrong about the brightness, you should ask will the speakers reveal the amps shortcomings?
This is a good amp but does not have the inner detail and exibits a little hardness on the top end (don't confuse this with brightness. The amp is not bright sounding.)
The Theil's will reveal everything in the amplification chain.
I used this amp with Vandersteen's with no problems. The amp is powerful with excellent low end control. Its issues start with detail and upper mids into the highs where it is not as good as some more recent (more expensive) amps. Lacking in ultimate transparency, it still throws a good sonic picture.
On the cheap, it's an excellent choice and one you should be able to easily live with.

Thank you for your thoughts. I guess at this point "good" is as good as it gets for me. Perhaps the next amp
I buy will be the end all, but I doubt it!

I drove my CS3.6's with an 8008BB for nine years, and although it did a good job, I found that the sound was not as refined as it could have been. Four years ago, I replaced it with a pair of Rowland 201 monoblocks, which made a significant improvement.

I think you'll find that the Aragon will give you good service and drive your Thiels for as long as you own it. It is good value; improving on it will cost you significantly more money.

Good luck, and happy listening!

I have never owned Thiels but do own a Aragon 8008bb that I bought here on Audiogon. It's dual mono design and 200 watts pc ame it as big tee says a very powerful amp. Runs in class A for the first 30 or so watts as well. I know there are better but I'm very happy with this amp and will not be replacing any time soon.
