Biggest "bang for the buck" audio gear you have owned(in your history)?


This is very subjective, and your opinion on your own systems/items is all that really counts.

From the beginning to now, these would fit that category for me: (in no order)

Original Large Advents
Dahlquist DQ-10
Conrad Johnson ART pre.
Original Monster interconnects and speaker wires.
Nakamichi SR-3a
AR Turntable
ADC XLM II
Audio Research LS-12
Magnepan 1.6
Magnepan 20
Wireworld Gold Eclipse III
Audio Technica Electret Condenser headphones 
Magnum Dynalab Etude and 108 tuners
Magnum Dynalab Receiver (original)
And in those "early days" special pressings and imported Jazz albums. 

There may be others I am forgetting, but these were very good items along my journey.

Back to the beginning...
1-AR turntable
SME 3009 tonearm w Shure V15 Type III
Hafler DH-220
Spica TC-50s
Dynavector 10X5 MKII MC cartridge
Oppo BDP-93 3D Blu-ray Player
Magnepan MG-1.5QR
2-Linn Klassik (office system)
Grado SR 60, 80, 225, 325 (office system)

Conrad Johnson PFR
Stax Lambda headphones


I had already given up on tubes for amplifiers.  The PFR made me open my eyes for solid state in the preamplifier stage. All for the outrageous sum of $850 (used) on ebay.  Incredible bargain IMO.  
AR turntable,Shure V-15,JBL 100s......the place to buy was Crazy Eddie's in Bklyn.NY,his prices were Insane.
Naim Nait 2
Magnum Dynalab Étude
Sota Sapphire

... all bought new over 2 decades ago and still running fine
