What amp for Thiel cs3.5's?

A fine neutral or slightly warm sounding amp should do the trick. Stay away from bright or sterile sounding amps. . .you would not be happy with these.

Ketchup, I had the 3.5s and couldn't get them to sound anything less than very bright. I tried Transparent cables to tune down the treble with only limited success. I tried the following SS amps with them. A B&K ST140, which didn't have enough power (about 105 watts). They need power in the 4 ohm and below range. A Musical Design 150-D (150 watts)and an Adcom 5500 (200 watts). Both of these amps had the power but still sounded bright. I was surprised because all these amps use Mofets, which are supposed to sound more like tubes. In addition, my pre-amp is a tubed model. Thiel was/is aware of this problem. I think that I remember hearing about a crossover mod/change that Thiel was offering on these 3.5s. You might want to check on that. Jim

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

A Parasound 1500a might be a temporary fix.........
