While my setup as a whole looks pretty awful, and pales in comparison to the perfectly clean and organized setup Will has, I think I've done alright being only 18. I've got a few different setups around the house, and then some random gear lying around. I have another 4 or 5 pairs of speakers in the garage that I didn't get photos of, the light in there is burnt out, and I'm to lazy to deal with it... Sorry for the awful photos, I ought to get some better ones eventually.
Main main setup:
Infinity Kappa 7 Speakers, my absolutely no questions number one favorite piece of gear. No other speaker I have holds any ground against these...
Yamaha C-65 Preamp and Mitsubishi LT-5V, the preamp I got from another very generous AKer to match the M-65 Power amp I got for next to nothing locally. The table isn't the best one I have most likely, but its just so damned neat looking, it stays in the main main setup.
Yamaha M-65 Power Amp, probably one of my other top favorites. I auditioned it against the AU-517 and BA-2000 I've had to work on, and for my tastes, it beats both of them, though the BA only by a small margin...
Downstairs Main Setup:
Spectro-Acoustics 200R, yet another contender for my favorites list. Awesome awesome amplifier, though it has a few issues with ground loops or something, which can be annoying. Sounds great though.
Marantz Imperial 8 speakers, probably one of the neatest looking speakers I've seen. They sound pretty good, handle most music well. Only complaint is the high frequencies aren't as clear as I'd like.
These are running HT duty downstairs near the above gear. First pair of speakers I bought.
Room Setup:
Realistic STA-120, Bang & Olufsen Beogram 2400, and one of the RtR (not BIC era) EXP-8 speakers. The STA isn't a great sounding receiver, but it has lots of cool lights, so I like it

. The Beogram is probably the best sounding turntable I have, and was the first turntable I had. The RtR has a complete piece of trash tweeter in it, as the original cone tweeters were blown, so they don't sound great atm, but I am going to fix that eventually.
The other RtR, a Technics SL-QL15, one of the blown RtR tweeters, and a woofer from some Infinity RS9s. The SL-QL15 is a fun turntable with the automatic track seek feature and a decent Ortofon cartridge.
Kenwood KA-6000, first amp I bought, first amp I got working. It sounds awful at the moment due to the fact that I've still not managed to recap it. Once I do, it'll take the place of that Realistic.
A mess of tubes I've managed to collect for projects. More driver tubes than I can count with a few big power tubes and rectifiers in there. I think I've got 2 Mullards, but the rest are pretty common vintage era brands.
Workbench with a VSP Labs TransMos amplifier which I am using as an amp project enclosure. Also got this from the generous AKer in a seriously toasted condition. I'll be building my 1300WPC amp in this thing.
A Harman-Kardon Three Thirty receiver on top of an ADS Model 10-01 digital delay, which I've never seen another of. The Three Thirty is a fun little receiver, with next to no power output, and an insanely warm sound. But it looks great, and does well on efficient speakers.
Infinity RS-4000, my main room speakers. Out of commission atm as they were being driven by the Spectro-Acoustic amp until I moved it downstairs. They'll be put back to use as soon as I get the Kenwood working well again, or find another amp.
Lot of writing, lots of stuff. And that's only about half of it. The rest is pretty much not worth mentioning, other than for the fact that it takes up a bunch of space. But whatever.
