One never knows what another person will truly enjoy,...
Or what will work in someone else's system. I haven't heard the NuForce or BAT amplifiers, and consequently I won't pretend to know the first thing about either until hearing each in my system.
I know someone who absolutely loves the NuForce 9.0 (doesn't have the .02 yet, much less the SE), and he has *extremely* revealing speakers. Does he enjoy grain and grit? Possibly, but I doubt it.
I've also conversed with someone who recently sold the much-ballyhooed $25K ASR Emitter II Exclusive and replaced it with a BAT VK600SE and a McIntosh C200 preamp he found on Audiogon. According to him, the BAT/McIntosh combo is "too much superior" to compare to the performance of ASR's top-of-the-line offering, and he paid less than $10k for the pair. Harry Pearson would probably take umbrage with his assessment, but he couldn't care less what Harry thinks. Good for him, because as soon as the search for audio nirvana begins to be about what someone else thinks, it's time to find a new hobby.
All of which is to say exactly what?
Unless you've heard it in your system, you don't know what you'll hear from any of these suggestions. NuForce amps were mentioned more as a joke than a serious suggestion in this thread, and they do fall into the extreme category (it's pure love or pure hate with them...not much between). Which category anyone here would fall into is subject to debate until they're heard in one's own system.
On the other hand, the BAT is easily the safer route IMO, albeit a significantly more expensive one, especially if paired with something like the McIntosh C200. The Moscode may be a safer selection, too, though it's relatively recent arrival and scarce reviews make it slightly bigger leap of faith. That said, the 33-day MBG and return shipping are sure to ease the sting of disappointment should it fail to impress.
Whether you choose to try the VK500, VK600SE, Moscode or (dare I say it) the NuForce, I honestly wish you the best of luck in your search. It can be maddening, and I hope you find what you're searching for sooner than later.
