This website is a shrine to the remarkable all-transformer-coupled amplifiers of Sakuma-san. Check out the "300B push-pull/300B push-pull end Pre-Main Amplifier" - this is a mono integrated amplifier with a built-in RIAA section. You think the the picture is surprising? Check out the schematic! This confection was featured in Japan's largest audio magazine in June 1988.

Well, true, Thom Mackris is my neighbor and hifi pal, but that doesn't change the fact he makes a damn good turntable - which sounds especially stunning with the Schroeder Reference and Tri-Planar arms, and the ZYX Universe and Dynavector VX-1s cartridges. Before you shell out a lot of money, buy a ticket on Frontier Airlines and come visit us in Boulder, Colorado. (Actually, we're neighbors in a little town called Erie, about 15 miles east of Boulder, and 25 miles north of Denver.)

I heard the A'Diva Ti at the last Rocky Mountain Festival, and was impressed how good they are. I don't much care for "mainstream" speakers - especially those aimed at the home theatre market - but the A'Diva Ti's sounded sweet, open and musical on a mid-price Chinese tube amp - and at a very competitive price, too. The sonics were easily in the $2000 to $3000/pr class, and Mr. Gallo did a terrific job calming down the metallic coloration that you hear from dome tweeters made from these materials.

These folks in Canada make some interesting TL loudspeakers - haven't heard them, but they look promising. I'm always a fan of TL speakers - the bass has a quality that's quite different than conventional closed or vented boxes, and I feel is more musical in character.

This attractive one-stop site provides numerous speaker kits, plans, driver specs, interviews, and construction articles. The author has gone the extra mile and used the powerful CLIO system (similar to MLSSA) to measure an interesting variety of sample drivers. Speaker systems designed around the advanced magnesium-cone Seas Excel drivers can be found here as well.

Reiki is what I do when I'm not fooling around with audio. Having grown up in Japan and Hong Kong (1956 to 1966), I find science, engineering, and mysticism are all part of the spectrum of experience.
