SOLD: RAAL-requisite HSA-1b Amplifier

Price: $2,995
Currency: USD
Ships to: USA (CONUS)

Selling my cosmetically, and functionally, perfect HSA-1b amplifier.

I am moving away from headphone listening. I have transitioned my (limited) SR1a listening to a combination of the original speaker interface (fed from a Chord Ultima 5) and the new TI-1a ribbon interface (fed from my WA234 MKII). I am no longer using solid-state headphone amplification for conventional cans, so do not need the HSA-1b anymore.

Includes the original ribbon-to-4-pin XLR adapter, power-cable, and all original packaging.


Price includes PayPal fees and fully-insured FedEx shipping.

Comes from a pet, child, and cologne free home.


Must have suitable presence here, or trade feedback on sites like Head-Fi/SBAF etc.

Not interested in trades.

Price dropped to $2,995.

This unit is now sold.
