step up from rotel?


Upgrading my amp, which solid state amp is a sleeper or much better bang for the buck than rotel, looking at the bat vk200 so far any others? thanks,Scott

Some more info on your system,room,budget,etc. will get better responses.Just a thought.
Scott,what other equipment will you be using,speakers,pre,source,etc.?This info really helps.

Here is a real simple explaination of ICE amplification.You can find out more by searching the web.

9. What Are “ICE” Amplifiers?
The Ice Power division of Denmark’s Bang & Olufsen (B&O) holds patents on its “ICE” amplifier, which is basically a Class D switching design (Pulse Width Modulator) with variants that B&O claims reduce distortion to levels associated with Class A amps, while retaining the high efficiency of Class D switching designs. ICE amps use a very high switching frequency of 384 kHz, which B&O says is 20 times as high as the highest frequency the ear can detect. The ICE amps also use feedback control to minimize the effects of the PWM design. Axiom’s engineering division took a different approach in the A1400-8 amplifier design. Axiom worked with International Rectifier to develop new silicon output devices and drive the MOSFETs in the output stage in such a way as to produce a perfect Pulse Width Modulated square wave at the output before the reconstruction filter. This approach also simplified the feedback network which made the amplifier more robust in its operation without being subject to oscillations or instability. The A1400-8 also uses a very high clock frequency (450 kHz) to allow for excellent transient response and non-aliasing in the audio band. The massive power supply is able to accurately output very high current and voltage to the loudspeaker over extended time periods.
