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.

2. Croft Micro preamplifier/phonostage.
3. Duelund DCA16 bulk wire as speakers cables. 

Cambridge Soundworks Tower 1 speakers (pre Newton) bought in 1998.  Still sound amazing.
A vintage Velodyne 15 servo. which I picked up at a sale from a storage unit facility for $20.   ,Made my day for sure. It even came with the remote.
