[net.audio] Amplifier Information Wanted

spj@spanky.UUCP (08/25/83)

I would like to get my system running in bi-amp or tri-amp to avoid the
use of passive crossovers, but I have been unable to find suitable
amplifiers for the mids and tweeters. I am looking for something in the
20-30 watt range that is clean and inexpensive. Building a power supply
doesn't scare me, so amp modules would be ok. Does anyone have info.
on amps of this type . I don't want an integrated amp because I already
have a pre-amp ( Hafler). 
   Can anyone steer me to a suitable product??????
