History aside, I was relieved to hear that the SQ-38u sounds like what it is: A vacuum tube integrated amplifier. A lot of contemporary tube gear sounds more or less like solid-state. Not the SQ-38u. And while it’s certainly not the least bit dated or slow sounding, you’d never mistake it for a transistor amp. It’s too holographic, tonally sweet, and pure. But if solid-state sound is what you’re looking for, Luxman offers a tasty selection of SS integrated models from which to choose. The company also offers a matching PD-171 turntable ($6,000) and D-38u CD player ($4,000) for buyers interested in maintaining the retro look.
