1) Jolida JD-100. No brainer. Here's an easy recipe: juice the tubes to NOS 5751s; switch the PC to something like a Chris VenHaus Flavor 1; hit the tube pins, RCAs, and PC/IEC prongs with Walker SST; and add a bit of isolation (granite, marble, maple, points, whatever).
2) Polk SDA 1-C speakers. Yeah, I know, Polk. They don't make these anymore. From the mid-late 80s, these have crazy wide/deep soundstage with excellent imaging and voice/instrument placement, wonderful top and low end (mids could be a bit more detailed); they do need plenty of current to make them shine. They respond very well to modest or even intense tweaking. I still prefer my 1-Cs to numerous, much more expensive speakers of today.
