PASS LABS HPA-1 HEADPHONE AMP - REVIEW

I did not expect to be as impressed as I am with the PASS LABS HPA-1, given its 2016-17 introduction and the various technical improvements that have come to other headphone amplifiers made in the interim, but time has not touched the viability, technical prowess, or wonderful musicality of the PASS LABS HPA-1. In truth, it has few rivals among those I’ve reviewed in recent years, regardless of price.
