Plinius SA301 Or Bryston 4bsst2?

Not that this is much help, but I successfully paired my 2.4s with a Pass XA-30.5 (and INT-30A). Those amps play up the imaging/soundstaging strengths of the Thiels and are nicely warm and textured, so you don't get burned with any brightness. Also, I never clipped the amp or felt like it ran out of steam, despite the low power rating.

I would try Pass Labs too, Schubert. X150.5 which is a Class A/B amp. The list price is around $5k. Of course you're not gonna pay retail...

Thanks Dave, the few times I've heard Pass amps I remember being struck by their musicality.

My INT-30A just sold for $3450 (before my previous post). I think that's a killer deal (and am still a bit bitter about it). Some pretty reasonable prices on the X.5 and XA.5 these days because of the new .8 series.

You're welcome, Schubert. :D
