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. 





jusam
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
Nakamichi 410 preamp.

Picked up one used for $90 10 years ago. Worth it for the stepped volume control alone. Still use it foday.
Absolutely, and without a doubt, two pieces come to mind for me. 
- Rogue Cronus Magnum II Integrated Amp
- Audioquest Niagara 1000

Couldn't live without them.
The biggest improvement I made, and not for killer dollars, was when I bought my first pair of serious speakers--Magneplanar MG -I.
