I've got to play along a little.

I have about 45,000 songs on mp3 on a 500GB hard drive. I load up my Zune when I hit the highway.
I have about 300 dbx-encoded cassettes I'm slowing turning into mp3's. That is, one 45-minute mp3 per each cassette side.
I probably have about 3000 albums, which I prefer. I, too, have a Discwasher, in the walnut case.

Had a Pioneer SX780 just like bbm's, wishI'd never sold it, but when I played the 1812 Overture through it, it clipped and shredded the rings around my speakers at the time (cheapo 3-ways). I've gathered more stuff over the years because it's a heck of a lot cheaper now.

Den (no TV):
Klipsch Forte II's.
Kenwood C-2 control amp
2x Kenwood M1 amps. One R, One L
Kenwood T-1 tuner.
Kenwood turntable until I find a new cartridge for the Rotel.
Pioneer CT-S99W cassette deck, plus a backup
SAE Noise Impulse Restorer (used by radio stations to eliminate record pops and hisses)
Pioneer 6-cassette changer (generally, only at Christmas)
Nikko reel to reel. Just got it back, heads redone, all new bands.

Bonus room (the good TV):
Advent Baby II's with a powered Advent sub hooked to a mid-level Onkyo receiver. That's my A/V setup. Loud, good, but stereo.

Garage:
Sony SAVA-7. Each speaker unit has 5 amps and it has digital processing.
All I know is they are small, self-amped, have RCA inputs, and are very loud.
Plus they have a remote that sits in my toolbox.
I run a generic, drugstore mp3 player into them that also has FM for football games.

I have a bunch of spare stuff in boxes, a dbx 224, a dbx 228, an high-end 8-track recording deck with pink noise generator and all that. I think I have a large Advent un-powered sub somewhere, with a Radio Shack mono amp I bought to power it.

As far as stereo, mono, quad, surround sound in all it's versions, I don't really get into that. To get it right, you need a speaker for each mic of the recording process, and I only know one guy who has that setup, a UofWI professor who has a wall with about 100 different speakers in it, each one EQ'd for a certain frequency.

Best listening lately has been a 45 of Good Vibrations, and Quadrophenia (if you have to ask...you won't like it, or you're too young). Though I'm not a Beatles fan, I'd like to get the original mono releases of some of their stuff.

I read Here, There, and Everywhere by a sound engineer who worked for George Martin, and the engineer says it's the best sound they had.

My high-freq hearing is shot (live for 6 weeks next to parallel runways with F-4's taking off, see what YOU can hear afterwards), but I do enjoy quality car audio, since that's where I listen to 75% of my music (via the Zune). My son "just wanted a decent stereo" in his truck, but he got a component system, anyway, that makes his Infinity setup sound great. I just can't abide poor car stereo if I can help it.

I wish I could afford McIntosh or Carver, but I can't.
However, I can play the 1812 (Cleveland Phil) without fear of anything but arrest.

As far as digital recording, we'll never really know what today's artists really sound like, since they're processed so much, even live. Now, Johnny Cash, we know how he sounded.

Oh, yeah, all my TV's are tube-type. I'm afraid Netflix is going to change that.
