sibelius, i've spoken w/john meyer of newform, as i'm also considering his speakers, & he sez that removing the passive x-overs, & going to active x-overs & bi-amping, gives even better results. since the newforms don't need any more power, instead of getting the stratos mono amps, i'd suggest getting another stereo amp & running them in a wertically bi-amped configuration. this will give ewe the best of both worlds - ewe will still have a separate amp driving each speaker, & ewe will also be able to actively cross-over the newforms. even if ewe still use the newforms' passive x-over (which benefits from switching to hi-grade caps, btw), since ya don't need the extra power, the ability to have seperate amps for each channel *and* still being able to bi-amp the speakers, will give ewe better results than yust having a single monobloc per channel. and, yule still have more power than ya got now, when using two stereo amps. ask klaus - i spoke w/him about this, when considering buying a pair of his amps. (i ended up w/a pair of electrocompaniet aw60ftt's).
i also highly recommend going to a tubed preamp - it will take your rig to another level, imho... :>) at under $1k, ewe can find a used melos sha-gold reference or melos maestro (last iteration of the sha-gold). i know of no other preamp that will approach the sonics of this unit at anywhere near the price, tho leafs may dispute this! ;~)
