I'd consider myself an on-again, off-again collector.
My first stereo was branded Realistic, handed down to me from my Dad when I was eight or nine.
My Dad had a wonderful Realistic receiver in the system that replaced the one he gave me. It has the trademark walnut veneer, nubbly knobs machined from solid blocks, midrange control, and one of those nifty light-up tuning needles (along with their proprietary "magic" tuning). I bought one a few years ago and played with for a while, then resold it. Then I bought an earlier receiver than that (I think it was an STA-100 if there was such a thing), was put off by the dark sound and worked my way through a series of seperates.
I regret selling the SA-2001 and TM-1001, those were actually great separates. I'm currently looking for a good pair to reacquire for the den.
At one time I had three of the SA-175C amps, plus two of the matching TM-175B tuner, but I sold all that except for one of the amps. What a great little amp for the size. Pretty low power but it has a very nice headphone amp, plus a nice phono stage. Not amazing but nice enough.
Of course there are the mini-7s. Can't get through life without a pair or two of those around. I'm a big fan of that speakers' midrange, and in the nearfield the bass is quite balanced too.
I, also, have had a succession of Radio Shack shortwave radios. Kinda wish I still had a DX-200- it's a fun radio.
