400-450Wpc Integrated to drive Thiel 2.3/2.4?


I fear my Musical Fidelity A308 at 300Wpc into 4 ohms isn't powerful enough to drive the Thiel 2.3 or 2.4's effortlessly and with enough authority as I'd like, so I'm throwing a net out there to see what other integrateds might work well.

I went from separates to this integrated, but if i'm buying the speakers and a new amp/preamp I can't afford it all right now.

Looks like the Bryston 4B's are well regarded as matching to these speakers, but at around $3K, then I'll need upgraded interconnects and a decent pre - I'm looking at a $5-6K outlay for it all, instead of (hopefully) just the speakers and a good integrated. I guess I'm looking at an integrated in the $2-3K range. Or should I save for a bit longer and go the separates route?

I'm guessing you have an 8' ceiling too? That's a mighty difficult room. Might be too small, especially with those dimensions, for Thiel's 2 series. I'd suggest some speakers with less bass output, perhaps one of Theil's 1 series, which would probably decrease the cost of amplification as well. I've heard the otherwise good sounding Thiel 1.6's with some high watt MF mono amps at a show, and wasn't too impressed. The Thiel rep admitted there were other better sounding amps for them.
BTW, extra power is always good, but in such a small room it might be less critical.
Unsound, are you saying it's a difficult room because of the difficulty of removing standing waves, etc. given placement limitations, or because the speakers can't sit far enough into the room or away from the listening position to really sound coherent? It's probably a combination of both but I wanted your opinion.

I'll try them with my current amp and if it isn't enough juice I guess I'll look for separates.
