Where did you buy your first audio gear?

1974 - Atlantis Sound in NY. Original Large Advents in walnut, Pioneer 939 Receiver (70 watts / side), BIC 940 Turntable w/ a Stanton 681 EEE cartridge w/ the silly little brush attached. 

Sounded pretty good but Blew two tweeters & a woofer playing the system too loud until I bought a second pair of speakers & then the amp would get hot but never failed. Receiver was decent, powerful, good tuner. Turntable was a piece of junk that seemed to be designed well but built poorly, should have gotten a Dual or Thorens. The stacked Advents are of course legendary w/ not the most extended high end but otherwise pretty good, even by today's standards. 

My first system (early 1980s; I was ~20 y.o.):

Pioneer Direct Drive Turntable (don’t remember source)

Pickering XSV-4000 Cartridge (Hillcrest High Fidelity, Dallas, TX)

Luxman L-450 Integrated Amp (Thompson Sound, Dallas, TX)

Luxman G-120A Graphic EQ (Thompson Sound)

Nakamichi LX-5 3-head Cassette Deck (Hillcrest High Fidelity)

Realistic Mach One Loudspeakers (Radio Shack)

Lamp Cord for Speaker Wire

Nakamichi and Luxman Factory Interconnects

I worked all summer to save up for the Nak, and dreamed of one day having a big Macintosh amp.

sourced various components/cables from: reference audio (gardena), systems design group (redondo beach), audio concepts (long beach), definition audio (next to systems design group), sound factor (encino), christopher hansen 2 (west l.a.)

Early 90s I bought my first "Hi-Fi" system from The Stereo Shoppe in Boise, ID
