The first system you had that was "high end/audiophile", by you standards

@tomic601 - and I'll bet that system can sound fabulous. I was supposed to hear a pair of Concert Grands or whatever the big daddy Bozak was (owned now by the son) but never happened. I'm using an MX110z in the vintage system, as you may know. Lots of tubes, knobs and chrome. Whoa! :)

This was around 1994-95:
Linn LP12 turntable
Aragon 47K phono preamp
Sonic Frontiers SFL-1 preamp
Dynaco Stereo 70 amp
Vandersteen 1B speakers
Pioneer Elite PD-65 cd player
Kimber Cables
ASC tube traps

One of the best audio synergy I have experienced.  I still remember that system!

1974: Dynaco SCA-35 integrated amp, an AR-XB turntable (don’t remember the cartridge, but probably a Shure), and AR 4xa speakers.  All bought with summer job earnings after my freshman year in college.  

@whart , Darn close. In 73 I had a pair of large advents and a pair of Klipsch Heresys a Fuzzlinear 700 and a  Marantz 7C. I did not get into ARC stuff until much later. I did pass through CJ territory. By the time I knew anything about Quads I had drifted into Acoustat. 

@mijostyn:
The Marantz tube preamp has withstood the test of time. I gather than the ARC SP3-a-1 (updated to some other nomenclature) is also still a contender, though I found both the SP3 and the later sp10-mk ii, though glorious in some respects, to be simply too noisy for the Avantgarde horns. But, in the right system, with a different sensitivity to noise, and perhaps some mods (I did have the SP 10 back and forth to Minn. many times, including for some "hot rod" version), they are classics too.
I much wanted to put a Marantz 7 tube in the vintage system, but I didn’t want to pay the tariff given the nature of the system and the fact that I have another, "main" system to play. But, those are the bomb. After what, more than 60 years? ( suck at math)
