your welcome, i hadn't heard of those, to be honest i prefer passive speaker systems with a decent seperate amp, as for bi amping, i'm not so sure either that or bi wiring offers any advantage over a single two core conductor. as for studiophile, that sounds like smoke and mirrors to me, (a bit like audio gain, superwhackpacks, A99 9.9dbi gain etc) especially at the price i see them selling for. they look more like high end pc speakers than hifi or studio monitors.
with hifi the only limitation is the depth of your wallet, but like cb and ham radio you very quickly reach a point of diminishing return per pound/dollar spent, at the bottom of the range every bit extra helps, but as you get to midrange equipment, you find the same size of financial increase brings a lot less performance increase, most average people would struggle to hear the difference between a midrange system and a high end one, but most will easily tell the difference between a cheap system and a mid priced one. same applies to speaker cables and interconnects.
even very moderately priced denon, yamaha or pioneer amps give excellent surround sound on mid priced speaker systems. rotel also make excellent gear but is a tad higher priced.
the amp i bought, jvc rx6001 cost two hundred quid (half the new price) as an new but end of line product around 2000 (was a bit stoned around then so dates are a touch hazy) and is used virtually everyday for tv, video games, internet and movies, it sounds as good today as when i first bought it, its never had any faults, its very basic but does the job exceptionally well, and is surprisingly good at playing stereo music, best 200 notes i ever spent.
modern pioneer,yamaha and denon equivalents under £500 are much better connection wise but sound very similar.
