This is a brand new amplifier featuring:

—9040 module uses the latest Purifi Gen 2 loop technology delivering substantially lower noise than previous Purifi models producing the most natural and realistic sound in Class D today.

—Vacuum tube input buffer using 6922 tube delivers smooth mids and highs along with the sonic ambience of vacuum tube designs.    Our tube buffer uses Sparkos 78xx regulators for the critical audio circuits.  Sparkos regulators are known to the quietest regulators in the industry.  Tube is run at conservative bias current to extend life to more than 2500 hours and unique auto bias circuitry makes tube replacement simple.  You can easily replace the opamps to tailor the sound.

—Power output at clipping: 400W @ 8 ohms, 750W @ 4 ohms, 1000W+ @ 2 ohms and stable

—Fully balanced design from input to output

—Complete protection from no-load, short and DC at the output.

—EMI/RFI filtered AC inlet

—MOGAMI Input wiring standard

—Heavy, custom designed aluminum case with blue LED pilot.  (LED may be dimmed or shut-off by switch)

—Silver-coated speaker output wiring with TFE jacket with option for Furutech upgrade

The VTV Buffer:

We use the Sparkos regulators for the important analog power supply. WE KEEP THE 5v DIGITAL supply completely isolated.
