what amp. to power areial 10-t speakers

I used a Pass X350 for 2 years with my 10Ts. Absolutely beautiful, silky, non-edgy, non-forward highs, mids, voices, strings. Vocals are another strong point. As good as the planars I haver heard, IMHO. Bass was not the last word in detail, but not boomy or pushy, and very deep. Overall, a very relaxing sound that was always satisfying. Soundstage was somewhat flat, but I think that the 10Ts do not excel in this respect. I would recommend the X350 on the highs/mids alone. Remember that the Pass X's generate a lot of heat.

I've had my 10Ts for about 7 years and love them. I'm driving them with a Levinson 331 amp which sounds great but gets a bit hard as a crank up the volume. I've been thinking about trying one of the newer class D amps but haven't done so yet. Some of the problem there is that my AR SP9 preamp (GNSC mods) requires a high input impedance from an amp and at least some of the class D amps have a fairly low input impedance (associated with the ice modules I believe).

I'm very interested in which way you go (and what others are using), so be sure to update this thread! Thanks!

Beemer is not getting these 10t's back!

I'm vertically biamping with a pair of Classe CA 301's and the sound is fantastic! I can crank the volume and the sound stays very smooth and no hint of edge. I can, however, quickly overpower the room. It takes a volume setting that is much higher than most anyone would want to listen to very long and the bass just gets boomy. I am starting to wonder about bringing in a tube amp for the mid and upper frequencies. Don't know if I want to mess with an active x-over just yet.

As to the comments about the 10t soundstage being flat. I did notice this early on in my experience with these speakers. To make a long story short, power and placement are magical with these speakers. I am getting very 3-D soundstage.
