Victor Kung of VK Music in Canada offers Japanese-made tube amplifier kits that cater to DIY enthusiasts. The amps that VK Music distributes are also available fully assembled—but where’s the fun in that?

AXPONA 2025 marked the debut of Computer Audio Design’s 1543 DAC Mk.III ($19,500), presented by CAD founders Scott Berry and Isabel Whitley. Also on hand were the CAD CAT (Computer Audio Transport, ca. $15,000) and a suite of CAD noise-reduction devices.

Room 1225 with Fidelity Imports offered a jolt of musical energy—vinyl spinning, bookshelf speakers punching, and a vibe that was more “groove and grind” than “rise and shine.” Even early in the day, the system sounded wide awake.

For me, one of the biggest surprises at Munich High End 2024 was the performance of Constellation’s new Revelation 2 stereo amplifier ($30,000), preamplifier ($25,500), and phono stage ($29,000). I’d expected refinement, but not this level of clarity; previous Constellation gear had sometimes struck me as a little dark. In Munich, the sound was beautifully illuminated, with wonderful colors and an ideal amount of brightness in the treble.

In front of a passive hallway display in the lobby of the Renaissance Schaumburg Convention Center, Mark Henninger and I caught up with TJ Goldsby, AXISS Audio's vice president of sales and dealer relations, and Takaya Inokuma, senior management director, Accuphase Laboratory. Together, we chatted about the first showing of the brand-new, entry-level Accuphase E-3000 integrated amplifier ($8975). Accuphase's new class-AB integrated outputs 100Wpc into 8 ohms.
