Lately, current amplification–based moving-coil phono preamplifiers have gotten a great deal of well-deserved press. For years, Haniwa's Dr. Kubo has been designing and selling super–low-internal-impedance cartridges because such cartridges work best with such devices. He has also been designing and selling his own current-amplification phono preamplifier.

Achieving room-filling, high-quality sound in a hotel room is difficult enough. Getting it in a cavernous ballroom is even more problematic. Yet, over the past few years at AXPONA, RMAF, and most recently at the February 2020 FLAX (Florida Audio Expo), Von Schweikert Audio, in association with The Audio Company of Marietta, Georgia, has managed that—and, other than the approximately 100 bodies occupying every seat in the house, they've done it without any room treatment, or without any that I could see.

I was all set to give up on moving magnets until the new Shure VI5-VMR (MR stands for Micro-Ridge stylus) arrived. In a word, it's terrific. I was slightly disappointed with the original V15-V: I just didn't think it was a significant improvement over the Type IV. What I missed was fine detail—especially in the high frequencies and during heavily modulated passages. The original V was not quite up to the sound of certain moving coils. Which is not to say the original V was a bad buy: moving coils cost twice the price and you need a stepup. I could recommend the original V without hesitation.

Designing and building a turntable isn't all that difficult. All that matters is in plain sight: Start with a base of wood, MDF, or acrylic; add some isolation "feet" for it to rest upon, and a spindle bearing such as any competent machine shop can fabricate, topped by a platter of acrylic or aluminum or suchlike. The motor can be an off-the-shelf AC synchronous type, fed directly by the electricity from a wall socket.
