I haven't heard any of the Arcam gear myself. I have heard good things
about Arcam's stuff, but it's been mainly in relation to their newer and higher-end gear (the AVR300 and particularly the FMJ stuff). If the Arcam dealer will let you demo in your system before you buy, it certainly could be worth considering.
Couple of purely general observations about
AVR200 vs. Model 1070... The Arcam's an older design, with no support for 6.1/7.1 (no Dolby EX, DTS ES, or Pro Logic IIx). It also offers only composite and s-video switching (no component switching at all), and the remote does not appear to be a universal type. The AVR200's bass management is also very basic (single global crossover that is fixed at 100Hz), which is a far cry from the 1070's quadruple adjustable crossovers and even from the RR2150's adjustable analog crossover. For a system that is likely to be mainly a stereo setup, the RR2150 may still be the best bet. For a system that may evolve into a surround setup, you'd need to keep in mind that in the case of the AVR200 you'd be investing in a receiver that is already several years out of date from the standpoint of feature set. Arcam's reputation for quality is pretty solid, but if you plan to slowly evolve up to a surround system you may find yourself needing to replace it to obtain features that are already considered standard in new surround receivers.
