Amplifier for VA Mahlers... IcePower?


Hello,
I am looking to buy a powerful amplifier to drive my Vienna Acoustics Mahlers, plus Oratorio center and two surround. Currently I have a bryston 4bsst but I am thinking to replace it with a 5 channel amp. Anyone tried icepower (1000 watts- 4 Ohms) modules with these speakers?
Budget is 3k and that leads me to used market.
Thanks in advance.
