I am having to reorganize and repurpose space at home and am consolidating down to a headphone system. The HPA4 is a terrific pre-amp with a 256-step, relay-based attenuator.
I am the original owner and purchased the HPA4 in July 2018 directly from Benchmark. This is the Black, Standard (not rack mount) model, with the original remote control.
SOLD for $2,400 plus insured shipping (if applicable). Payment by Zelle. I am in the Washington, D.C. region if you want to arrange local pickup.
The pre-amp is in excellent condition. It has been sitting in my smoke-free, pet-free living room and doesn’t have any dents or nicks or other marks on it.
