Hi again Leland.I like the imaging of the Pi's. It's wonderful to have the wood stove in between the speakers singing wonderful things to you :-).
I gave up on vinyl and went to cd's. I have a friend at work with a massive collection of MP3's he's willing to copy for me. Less than 200 bucks for a hard drive and I can listen to different tunes until the cows come home. They've got things like the Sound Blaster wireless that let transmit songs from the bedroom computer to the living room stereo.
I'm working on using Bills David plans for the woofer with a Fostex/ ribbon combo up top. Not being an EE I'm sure I'll be bending a few rules, but I expect they'll sound pretty decent. I keep having this image of these 3 1/2 foot speakers hooked up to a T-AMP and a one inch cube MP3 player with a gig of tunes on it. Up to 4 hours of battery power on both the amp and MP3 player to listen to 15 watts (at 4 ohms) with 98 SPL speakers, take it where you can carry it, kick *** sound. What a ghetto blaster.
Gotta love it.
Have a good night.
Grant.
