REVIEWS

Simply put, the HSA-1b delivers the most enjoyable, immersive, engaging and outright addictive listening experience I’ve had with the SR1a, short of spending more than double the asking price on high-end speaker amplification!

In fact, I like the HSA-1b so much with the SR1a that I would have had no qualms about buying it just to drive them, even though that wouldn’t be taking full advantage of what it offers. But since I found it similarly compelling with almost every other regular headphone I tried it with, and it reduced my desktop box-count into the bargain, it was an even easier decision - and better value as a result.
