Default FS: AMB M3 Headphone Amplifier (Finished)

Selling my self built AMB M3. M3 board is populated as a standard build, all Nichicon Muze and Wima capacitors.

Also has the variable Bass Boost option.

Custom made case with frosted plexiglass bottom and accent lighting (Red). Laser cut top in art deco style with red MMM filled with enamel. Four aluminium and rubber feet.

A custom built capacitance multiplier power supply running at 29Vdc. (Link for info: Capacitance Multiplier Power Supply Filter look under 'The Final Design' section, but it's single sided)

Power switch is a bulgin type momentary push button with a custom programed ATTiny switching on power and audio. On Power on, power will switch on then 2 seconds later audio is connected; on power off, audio is switched off, then power is switched off 2 seconds later. To avoid any popping, noises, etc.

Double fused switched power entry, switching on 110AC power on back will turn on the ATTiny driver.

Has 1 1/4" locking Neutrik output, 1 1/8" input on front and RCA's on back.

Comes with 2 AD8610 in Right and Left Channel, and a OPA627 in the ground, this seems to give a good combo of highs and lows.
Will also include 2 NTE OpAmps, they sound quite good for what they are (Have great bass, but a little hiss in the background on high volumes)

Powered both my D5000's and HD650's with ease and great sound.

Selling because I built a B22 and don't need 2 SS amps.

Looking for $450 shipped!

Please contact me if you have questions.

I don't have feedback here but here is my ebay 100% feedback: eBay Feedback Profile for ryokoshonor
