Up for sale is Firestone Audio Big Joe V1.3 amplifier.
In like new condition with about 100 hours on it. Comes with all original paperwork, box, parts, tool, etc.
By far the absolute best of the 'budget' level amps I have heard for the AKG K1000s. At low listening levels, I could hardly tell the difference between the Big Joe and the Aleph 3 when driving my K1000s. With the proper opamp rolled in, it has a warm tube-like sound. And it also makes a killer amplifier for efficient loudspeakers.
I am also including 2 of my favorite opamps for the Big Joe (in addition to the stock opamp that Big Joe shipped with).
Opamps included:
BB OPA2604 (stock)
BB OPA2227
AD827AQ
I am also throwing in an opamp puller and a power cord (which wasn't originally included).




I paid around $270 for the amp, opamps, opamp puller and power cord.
My asking price is $215 (firm) shipped to anywhere within the CONUS, paypal fees included.
Sorry, but I am only willing to ship to locations within the CONUS.
No, I am not willing to break up this package deal.
I will also entertain trades at this time.
Feel free to PM me with any questions/concerns you may have.
