Ray Samuels Audio “SR-71B” The Black Bird, fully balanced portable amplifier
Will Ship To: Anywhere
Hello. This SR-71B Black Bird, is a fully balanced input-output portable amplifier and has less than 50 hours on it and is in perfect condition. You can use the square 4-pin balanced or 1/8" single-ended inputs and outputs (I also have a square balanced 4-pin Moon Audio Black Dragon cable for the JH Audio or Ultimate Ears Custom IEM's, if interested in a combo deal).
If you are not familiar with the SR-71 Blackbird amp, specs and pictures can be found at : http://www.raysamuelsaudio.com/products/sr-71b
It has been housed in a smoke-free, loving environment. Even though it is a portable amp, with it's 3 position gain switch it has more than enough power to drive 300Ω full size headphones like the Sennheiser HD6XX or HD800 headphones.
MSRP is $650. Asking $550 plus shipping.
Thanks for looking
