Intregrated Amp for Thiel 2.4 s

First suggestion is don't do it... Too many people have tried to power thiels with an economy mix of electronics and regretted it. Pick up a very good used power amp for at least $2-3k used. I personally prefer the Sim Audio Moon W5 for this. If you are able, run the source direct into the power amp initially. Add a tube linestage down the road.

The 3 essential criteria for any amp powering thiels are power, current, damping factor. You want about 200 wpc into 8 ohms. Something that doubles the power as the resistance halves. Very high damping factor, don't go less than 400. Damping factor advertised by the manufacturer is computed with 8 ohm load. The W5 damping factor is 800 but my thiels drop to 2 ohms so at that point the damping factor is only 200.

I just auditioned the Thiel 2.4's with the Musical Fidelity KW500 yesterday in Illinios. I actually went to audition the conrad-johnson Premier 17LS2. I spent four hours listening to the c-j with Vienna Acoustics speakers. Then the Musical Fidelity KW500 (I have MF equipment myself) with the Vienna Acoustics speakers.

The salesman then brought in the Thiel 2.4's and set them up with the KW500. It was unbelievable! He told me that my MF A308cr Power Amp at 250 wpc in 8 ohms/450 wpc into 4 ohms would work fine too. I'm looking into selling my B&W Silver Signature's and getting the 2.4's too now.

You can check my system out here, and also see that I used to own the Krell KRC-3 and KSA-50S combo and replaced it with the Musical Fidelity A308cr pre-amp and amp combo.

Jazzdude is correct. I tried a VK-300x on my 2.4's and it just didn't work for me. They need some power. I'm using a GamuT D200 and the sound is significantly better with more authority. I'd say the W-5 would be a good choice also.
