Personal speaker evolution

OK, so here is a thread I haven't ever seen here: What speakers have you owned? starting with the earliest, price paid, new/used, and perhaps the models that really impressed you (for the price) in CAPS.

Rat Shack Something or others, $120, new
Fisher Something or others, $280, new
ADS L710's, $550, new
Snell A2i's, $1100, used
BEVERIDGE SYSTEM 3'S, $1000, used
Martin Logan CLS, $1400, used
MARTIN LOGAN SL3'S, $2300, used
Yes, this really is an interesting thread and I would love to see others post on it.

1991 Linn index (first hifi set up. Sold perhaps completely the wrong setup for electronic music but oh well...)
1991 Linn helix (index not sounding anywhere big enough,)
1995 Cerwin Vega AT40 (a lot of fun but ideally needed a big amp)
1998 present Rega Jura.

Beginning to demo speakers to replace the Juras which are switching rooms!
You probably want a 5 channel amp. For what you have Marantz or Anthem or NAD are all good bets. They give real power. I'd personally go with NAD or Anthem as their amps seem to power all channels and don't get overloaded (from what I hear as I only run two channel). I have an older B&K St140 that would power two of your channel nicely. Actually it's a good amp for the price as it is pretty powerful. Then you can get a nice three channel amp for your fronts and use a pre/processor. If you went that route, you keep your upgrade options open as you can just change to better amps later on or eventually save up for a strong 5 channel amp or even just get a new processor when the latest changes.
