“The HA-1A breathes life and light into music in a way that transistors— and many tube amps—simply cannot. It makes musicians sound here, not there. This is what SET can do: not transport you to the recording venue, but transport the performers to your living room… Immediacy, intimacy—nothing can top tubed SET. Those experts who opine that all hi-fi sounds “electronic” haven’t spent much time around SET tube amps. I doubt that the HA-1A works its magic by fooling with phase relationships or blending channels. What it does, it does naturally: expand the soundstage so that it floats outside, not inside, one’s cranium. The effect is not as natural as listening to a good pair of loudspeakers, but the experience is enjoyable on its own terms. The HA-1A has a way of making headphones sound less like cans (British slang for headphones) that is downright…uncanny. And the HA-1A did bass—rich, full, tuneful, tight bass. I’ve always thought my Sennheiser HD 600s sounded a little thin and bass-shy. Such is not the case. The HA-1A may be the best thing that’s ever happened to headphones. Of course, you’ll need a good CD source to reap the maximum benefits, but the sound quality I heard was extraordinary. You can have more than a taste of high-end bliss for relatively little money—champagne sound for beer-budget bucks. Man, you gotta hear it!”
