FS: AMB β24 Power Amplifier - HiFiMAN headphone adapter available (last price drop)

Will Ship To: Canada, CONUS

I am currently raising funds for a road trip around North America, and thus need to sell some of my gear.

 

I originally bought the β24 to use with my HE-6, but I had to part with them shortly before receiving the amplifier. I have kept it stored since, so it's had negligible usage by myself. The previous owner (and craftsman) took great care of it. The only wear I can find is a mark about 1/2 inch long next to the LED on the front.

 

Original sales thread: http://www.head-fi.org/t/611385/amb-24-amplifier-fedex-shipped-and-insured

 

I am looking for CLOSED For an extra $75 I can also include the HiFiMAN HE-Adapter if you plan to use the amp with headphones. Send me a PM if you're interested.

 

Let me know if you'd like to know more info about the unit (pictures, etc.), or about the β24 in general.

The parts used and settings were essentially the same used in AMB's build.

- Pesante Dissipante enclosure from hifi2000

- Cardas quadeutectic solder used for entire build

- Vishay/dale and caddock resistors

- Nichicon capacitors

- gold-plated binding posts, Neutrik XLR sockets, relay used for power on/off

- teflon-insulated silver-plated copper wiring used wherever possible (all signal paths)

- The transformers and unregulated power sections are shared, but the regulated supplies (sigma 22's) are completely independent

- The transformers used are a custom 30VA SumR transformer for the regulated section and a 630VA DIYcable transformer for the unregulated section (AMB uses a 500VA Piltron in his build).

I know you said you parted with the HE-6, but do you have any impressions of how well they pair together?

post #4 of 4

They pair very well together.  I had a chance to have this amp come through my place before it was sold to Benjamin6264.  Also this same amp was said to crush the Darkstar at a meet about two years back.  

 

This is out did the Emotiva amps I had at the time, also a pair of Rotel mono blocks - all compared with 3 pair of HE-6s.
