Those reading likely are very aware of the accolades this piece of electronics has had bestowed upon it. The upgrades were over the asking price of the unit.
The A upgrade includes:
Upgrade McCormack DNA-.5 DLX to Revision Gold A + and converted to monoblocks. This is for a pair. How often do you see these?
Rev-A Upgrade $1200,00
Additional upgrades and costs:
Black Gate Output Bypass Caps $280.00
Jensen transformers balanced input system $450.00
Soft Recovery Diode Bridge $250.00
Cardas Deluxe Binding Posts $80.00
WBT Topline RCA jacks $100
Musicoat Component Treatment $200
SMC circuit revision with ultra premium NP Blackgate capacitors
Full upgrade of the driver board
Full upgrade of the output boards (wiring and rebuild of high performance components)
This is a pair of monoblock McCormack DNA-0.5 amps, upgraded by SMc Audio. These were given the top-tier Revesion A upgrade, which, previously, was the top-of-the-line upgrade offered by SMc Audio.Each of these amplifiers, with both balanced and unbalanced inputs, puts out an astonishingly clean 400 watts into 8 ohms, doubling down into 4 ohms, etc. A description of the mods, from a piece in Stereophile by Kalman Rubinson: "Rev.A ... is, as SMc calls it, "the Full Monty!" Every single part affecting the signal, including output-stage caps and emitter resistors, is replaced with what he feels to be the best available, resulting in a complete rebuild of the amp." Additionally (as per Rubinson's piece), the upgrades "eliminate the DC servo by reducing the DC gain to near zero." You also get Cardas binding posts, Kimber RCA jacks, Cardas board-to-board wiring, and heavy-gauge Van Den Hul output wiring. And there's more: The mono conversion not only adds a balanced input,not only brings the amp up to its mighty powerful specs, it also makes it a "true balanced" device. This, from SMc's FAQ page: "The description 'true balanced' usually refers to equipment designed to be fully differential from input to output. This requires two fully independent signal paths per channel, and is necessarily much more expensive than a similar unbalanced design. ... [W]hen you are ready for the ultimate in amplifier performance, a matched DNA monoblock pair will give you 'true balanced,' fully-differential operation that is out-of-this-world!"
