I've always liked the look of the Wyetech Topaz.
Maybe I'll check it out someday.
It sure looks special, in a good way I think.
It's great that it can cruise at 18 watts and chuck out 50w in pulses.
I'd have to find a speaker that would match.
I'm to much of a bass lover still, but if I could find a speaker that would work, i'd give it some
serious thought. 12 large is a lot of money for just 18watts I think.

if you're a bass lover, then you need to get a pair of subwoofers, actively crossed over to your mains w/an outboard x-over, & driven by a solid-state amp. then, you could use tube amps with *any* speakers you want. and, imo, your mains will sound better, (even if you stuck w/solid state amps for your mains), - the upper bass/lower midrange will perform better, since the driver is not having to deal w/the lowest frequencies. aa of course, having tubes on your mains will also effect an improvement, imo!
and, i see no need to spend $12k on 18w amps. retail $800 will get you a killer 5wpc single-ended pentode amp - the almarro a205a-mkll; & retail $2100 will get you a killer 45w per channel pair of set amps - the audio mirror 6c33c monoblocks. mcalister audio also has some nice looking set amps - 16 & 22wpc, at $1100 & $1550 respectively - i have never heard them, but they are supposed to be outstanding amps...
