My HA1 was actually used as a fully balanced pre-amplifier driving a pair of Bel Canto REF600M monoblocks (rated class A by Stereophile) with highly satisfying results. In my experience, HA1 can compete with any top notch fully balanced class A pre-amplifiers.
Superb build and part quality.
Selling to downsize.
Local pickup welcomed and buyer can check the item in person.
