I saw the two pics of your Lexicon MC-8. It might be that you and I are the only forum members who indulge in both Logic7 and SM Involve.
Perhaps, though i have the mc12hd theae days. The mc8 was a nice rig as well.
I got into quad at the same time i got into vintage audio, as a QRX was my introduction. I then set out on a CD-4 mission, and then Q4, and the rest.
After a couple years i found...sacd. what? Multichannel? Then home theater as my home git bigger, and my spending account grew. I found tons of downloads at Dreaming Spires, and began looking for quad files already decoded that i ckuld burn to disc, and therby play on my HT setup without a decoder. They quad vinyl was put away, though never sold. I continued to collect them when in good shape. Then i had some years off due to personal stuff.
Ive always kept my quad receivers because they do far MORE than play quad material, and incorporate them into todays uses. The last few months ive been longing for the orig quad of my early discovery, though know that it may well not be as "good" as what some newer formats offer, its far more enjoyable. I like to tinker. I was looking at my Marantz 4400 a couple weeks ago and realized it diddnt do QS like the Sansui does.
In searching decoders, came here and saw the SM. Found one in AU a few weeks ago on ebay for a start bid of 40.00. I won. I felt bad for the seller and paid an extra 20, offering more.
What i had not realized, was mine was early version that did not do QS, even though the manual says it does, no switch for that on the front. Not the only discrepancy in the manual, but oh well. I then ordered the v2 unit yesterday due to what this DOES offer me with quad, but yes with the 2 channel and more importantly, the sub out. I can finally add a sub to my vinyls in a way that pleases me without a tape loop or splitters.
I run 4 systems usually.
HT, which doubles for the sacd/dvdA
Staight vinyls 2 channel with traditional Mac and Klipsch (modified)
My test system for just monkey play between new and old, to rotate unused gear and hear different combos,
And then Quad. Seems like these new units, though analog; still offer a perfect combonation of new tech, without taking away from the old school feel that got me hooked into vintage to begin with.
