Cayin HA-3A 真空管耳機擴大機

I've been using this for a few weeks now and the soundstage with my Sennheisers opened up significantly, especially in the mids, which feel much more present and detailed than on my solid-state amp.

The tube glow at night is pure eye candy, but what really sold me is how dead-quiet the background stays even at high gain. Hooked my planars up and the soundstage opened up in a way I didn't expect from a desk amp this compact. It's a keeper.

The chassis feels incredibly solid, and the tubes give a warmth to vocals I’ve never heard from my other amps. It’s a joy to just sit and listen for hours without fatigue.
