Primare A35.2 power amplifier

My writing desk looks out over a large garden with chickens, bees, and feral cats. My chair sits only six feet from loudspeakers, playing softly on my left. Between the speakers sits whatever painting I am working on. That painting hangs no more than 10 feet from the oscilloscope and drill press in my kitchen. Best of all, my desk is only six feet from squadrons of ravenous sparrows attacking the suet cage on the fence outside my window.

PMC fact.8 signature loudspeaker

Back in the Dark Ages, loudspeaker design was commonly based on semi-enlightened experimentation, with new enclosure configurations appearing almost monthly in professional and consumer journals. One of those, published in Wireless World in October of 1965, was A.R. Bailey's transmission line, a long, selectively resistive, folded-and-sometimes-tapered tube that loaded the back of the (woofer) driver for low-bass reinforcement.

. . . and I feel fine

The High End 2020 show, scheduled to take place in Munich in mid-May, was canceled due to concerns about the coronavirus. The California Audio Show, which usually takes place in late July, is also off, although the reason for its cancelation isn't clear. And as we've just learned, AXPONA, the biggest show in the Western Hemisphere, has been postponed from its original dates (around the time this issue hits mailboxes and newsstands) to the second weekend of August.

The reason, of course, is concern about the spread of COVID-19.

Recording of May 2020: The Hot Rats Sessions

Frank Zappa: The Hot Rats Sessions
Zappa Records/UMe ZR20032 (6 CDs). 1969–2019. Frank Zappa, prod.; Joe Travers, Craig Parker Adams, Jack Hunt, others, engs.
Performance *****
Sonics ****

Frank Zappa's first real solo album (he conducted but did not play on Lumpy Gravy) is probably his greatest recording and perhaps his most uncharacteristic in that his singing voice is nowhere to be heard. The one vocal, "Willie the Pimp," is sung by Captain Beefheart, whose Zappa-produced pinnacle Trout Mask Replica was released the same year (1969).

Going Dutch (& Dutch): a Conversation with Martijn Mensink

In his review of the three-way, active Dutch & Dutch 8c loudspeaker in the August 2019 issue of Stereophile, Kalman Rubinson concluded that "The D&D 8c demonstrates that active, DSP-empowered speakers are the future." I was equally impressed by the 8c's measured performance—a superbly flat on-axis response and an unmatched control of dispersion over the entire audioband—and asked to borrow a pair so I could experience the speakers in my own listening room.
