Anyone heard the new TacT SDA2175?

This new PWM amp has recently been made available, see here for details.

It seems to be built up around an analogue differential input stage similar to lcaudio.com's Predator SE, built around its ZAPpulse mopdules. They cost approximately the same (except that you can DIY around the ZAPpule modules), and having a comparative review would be very interesting.

I think that the TacT amp would have a better second hand value so I'm tempted to get one to try out since I find this technology very interesting. Have anyone heard it?

Two reviews in norwegian and danish for those that can read them..

Did you get this? I'm interested also.

I got a M2150 in the end. It sounds fabulous. I hear people saying the SDA2175 sounds good though.

Well..i don't know about sound, but the specs they wrote is pretty artful:
* SDA2175 generates 75% less heat then class AB..(SDA2175 have idle consumption are 30W!!)
*All loudspeakers present a reactive load to amplifiers, because impedance varies with frequency.
In analog amplifiers, this results in greatly increased distortion. (BTW, output impedance of the SDA2175 from 35mOhm@1khz to 400mOhm@20khz..it is cool?)
*S/N ratio 117 A-wgt. (This is "extremely low level of noise"?)
* THD A-wgt. also! (What about freq. sweep and no A-wgt?)

I've bought one! It amplifies, without adding to or taking anything away from what its fed. It's a steal at £740!!
