Katz’s Corner, Episode 7: Mosfet Magic

This story originally appeared at InnerFidelity.com

Something had to give: Tyll has given me the assignment of evaluating a bunch of midprice phones. But I feel that the amps I have to drive them are not completely up to the task. The Burson Soloist is fun, punchy and “tubey”. The O2 sounds comparatively transparent and is a great bargain, but how would it compare to the big guys? So I knew I needed to include a transparent high class amp to drive and test these phones. But Mary would divorce me if I proposed buying yet another expensive headphone amp. Instead I found a solution: Build one instead. The process has proved to be very rewarding in all respects. Let me tell you about it here.

Formula 4 tonearm

Not the easiest tonearm to set up (let your dealer do it if you aren't overly skilled at such things), this English-designed and Japanese-made device is the best pivoted tonearm we have tested to date, and at a very reasonable price at that. Polk Audio is importing them and distributing to dealers, most of whom sell them for around $130 to $140, and some buyers have managed to purchase them directly from stores in England for as little as $80. We received two samples of this for testing, one directly from the US distributor, Polk Audio, the other from Natural Sound, a Nebraska dealer and (naturally) one of our advertisers. Suffice it to say that both samples were identical in every perceptible manner.

Arnie Nudell: From Infinity to Genesis

Arnie Nudell is one of a handful of designers who could justifiably be called founding members of the high-end audio industry. With Cary Christie, and John Ulrick, Arnie co-founded Infinity in his garage in 1968 and recently joined forces with Paul McGowan, the co-founder of PS Audio, to create Genesis Technologies, the Colorado-based company formed to build ultra–high-end loudspeaker systems.

I visited the Genesis factory in September 1994 and spent some time with Arnie and Paul discussing loudspeaker and amplifier design, and high-quality music reproduction. I asked Arnie how he became involved in high-end audio.

The 2015 Capital Audio Fest Starts Friday

This year's three-day Capital Audio Fest (CAF) opens on August 28 in Rockville, MD, relatively close to the nation's capitol. In a new, unquestionably friendlier and eminently accessible location, the Hilton Rockville, the show promises, at press time, up to 39 active exhibit rooms, probably more than the 118 "officially listed" brands and exhibitors, and a potential 300+ products.

London Calling

I swear I did not plan it, and it wasn’t obvious on the Google maps I pored over before we left but the back door of the fabulous Soho Hotel spilled right out onto Wardour Street, which was a block from Berwick Street, famous for its cluster, or more like the best cluster of independent record shops in London.

Wilson Benesch Square One Series 2 loudspeaker

For many years, I've been a fan of the loudspeakers made by the British audio company Wilson Benesch. Their speakers definitely have their own personality. I first reviewed a Wilson Benesch loudspeaker while a columnist and reviewer for The Abso!ute Sound, and how that came about was amusing. As WB's then US importer was packing up his exhibit at the 1999 Consumer Electronics Show, by mistake he put labels with my address on them on the boxes containing the show samples of WB's revolutionary A.C.T. One, the first loudspeaker to have a curved carbon-fiber enclosure, a sloping top, and a baffle of cut steel. And a very nice late Christmas present they were, too.

B&W DM-6 loudspeaker

The B&W DM-6 is the second "phase-coherent" speaker system we have tested. (The first was the Dahlquist DQ-10 in January 1977.) From what we see in the latest ads from the US, England, and Japan, there will be more forthcoming. One speaker manufacturer who has been around for a long time and is currently pushing his own "phased" systems observed that many of his competitors' designs are being introduced merely because "phase response" sells these days. Yet the truth of the matter is that the experts still do not agree as to whether linear phase has any effect on reproduced sound.

The DM-6 is an expensively made product using three drivers specially designed for it. The woofer cone is of Bextrene plastic, common in England but rare in the US. The midrange unit is a 6" cone of DuPont aromatic polyamide, "Kevlar," which is claimed to have extremely high internal damping. (This is the first acoustical use of this material that we know of.) The tweeter is a ¾" dome. The cabinet is of complex construction, heavily braced and lined with bituminous felt, which can significantly reduce cabinet resonances.

The 2015 California Audio Show: Not Just Another Show

The California Audio Show may have been smaller than in years past, but its proportion of excellent sounding systems—6 out of 32 or so, if you count exhibit rooms that had more than one system in play—was quite high. For this reason alone, I believe the show offered great value for attendees. And it also offered some great views of San Francisco International Airport, as this shot, taken through my 7th-story hotel window, attests.

Here is the word on show attendance from show organizer, Constantine Soo: The final number is 2300 attendees.

The Nelson Pass Seminar at CAS6

It's a rare day when famed amplifier designer Nelson Pass leaves his bench to deliver a seminar. It's even rarer when that seminar is geared toward consumers rather than what he calls "specialists." In fact, at the start of his talk, Nelson confessed that after almost 50 years building amplifiers, his CAS seminar was his first ever tailored specifically toward consumers.
