We are going back six months for a free Rev5 upgrade to the Fet Valve EXR amps (applies to the amps only). Shipping cost $35.00.
Older than that its $200, which is exactly what it costs us (zero profit) plus $35 shipping.
The Rev5 upgrade includes improvements to the regulated power supply board for better regulation as the amp approaches clipping, but more important, major upgrades to the audio circuit boards. The linearity of both the tube and the mos-fet sections of the audio circuit is significantly improved. The amp makes power with a larger selection of tubes too.
Musically, probably a lot more of what people like about SET sound, but with gobs of power and dynamics. Certainly a major step forward in transparency, definition, and range extension, both top and bottom. Its called Rev5 because we went through Revs1-4 privately here in house for months testing and listening to learn what to do for Rev5.
I think you will like it.
