Not only does Jeff Zhu’s much-anticipated flagship Class-A headphone amplifier with stereo preamp functionality achieve state-of-the-art technical performance from a discrete topology, it seemingly does so without making even the slightest of compromises on musicality. Bliss’s fully-balanced, dual-mono design and precision stepped relay attenuator with auto-adjusting gain combines life-like timbre and holographic imaging with captivating detail and dynamics to deliver an effortlessly natural and spacious listening experience with headphones and loudspeakers alike. I haven’t heard better at its price. RB
