One word: Hoard. They are so rare, I buy all the SoundStream I can. I actually have those plus a few T-1 tuners, 4 DA-1 amps, 6 DA-2 amps, 4 RA-100 MKIII amps, three phono section cards, two SN-1 networks, a dozen or so remotes, a C-2 surround processor/preamp with remote, 10 keypads, an IR remote receiver, a couple of speaker switches, a couple of power strips and a super rare Simul-Source remote keypad test unit. The SS C-1 is the closest thing to the Conrad Johnson Premier 17LS-S2 that I have ever heard. I don't want to hijack this thread, so maybe I'll start a new one...
Hey Kev, It seems that the only reason they are so rare is because you are hoarding them.
