Up for sale is my. If you follow me on instagram you have seen many pics of this phenomenal sounding amp that offers you many tube rolling options. If you're wondering why it is for sale, it is because I like to audition and review gear, and I just don't have the space for this when I have several other amps in rotation. There are no problems with it. It looks and sounds excellent. I have used it with AKG 701, Beyerdynamic DT990 and T90, Grado GS1000i, HiFiMan HE-500, Shure SRH840 and I have no complaints with any of them. This has enough power to drive pretty much everything you throw at it.This amp sounds incredible, is made of high quality materials inside and out (upgraded power supply - no hum), has tons of power and is very sensitive to tube rolling, so you can dial in the sound you want. The amp is used, but is in great condition and has no damage.You will receive the amp, power supply and umbilical cord. I will try to include a generic AC cable as well as this did not come with one and I am using my own cables.You can read all the technical specs on the RSA website here: http://www.raysamuelsaudio.com/products/raptor Please feel free to ask questions.. I will ship internationally anywhere USPS delivers at the exact cost. Local pick-up is also an option if you are near Chicago.Payment via paypal or bank wire.
