Recording of May 1982: The Sheffield Drum Record

666shefdrum.jpgThe Sheffield Drum Record
Improvisations by Jim Keltner and Ron Tutt (drums)
Sheffield LAB-14 (LP) (1981). Reissued as FIM DXD 001 (CD) (2010). Bill Schnee, Doug Sax, prods.; Lincoln Mayorga, exec. prod.; Steve Haselton, Bill Schnee, engs. TT: 13:49.

There was a time when drum records were as common as records of steam locomotives and thunderstorms. It has been so long since anyone has tackled any of them that a lot of technology has gone over the dam, but they are precisely the kind of program material which illuminate the state of the audio art like nothing else. Thus, Sheffield's Drum Record emerges as a landmark—a technological tour de force that should discourage anyone else from issuing a similar disc until the state of the art advances by a few more years.

Moon by Simaudio at 35

Established in 1980 by Victor Sima as Sima Electronics, Canadian audio company Moon by Simaudio Ltd. celebrates its 35th year in the audio business in 2015—or, as its ads say, "35 years of passion." To mark the event, Simaudio had a party at Executive Stereo, their Toronto dealer (see photo above). It was a fairly low-key event, with a handful of Toronto-area audio journalists—including yours truly—and representatives of Simaudio attending.

Vinyl Resurrection at the 2015 New Music Seminar

Left to right at the "Vinyl Resurrection" seminar: Nina Palmer (Ross Ellis Printing), Steve Sheldon (Rainbo Records), Michael Kurtz (Record Store Day), Bryan Burkert (The Sound Garden), Matthew Johnson (Fat Possum Records), and Mark Piro (Spark/Razor & Tie).

The New Music Seminar 2015 was a three-day (June 21,22, and 23) conference held in New York that invited music industry insiders to dialog on the current state and potential future of the music delivery business. Right away I knew I wasn't at CES...

John Hollenbeck: Songs We Like a Lot

We seem to be going through a big-band renaissance. In recent months, I've hailed the latest albums by Maria Schneider's Orchestra, Steve Coleman's Council of Balance, Ryan Truesdell's Gil Evans Project, and now—in some ways, the most adventurous—John Hollenbeck's Songs We Like a Lot (on the Sunnyside label).

Up On The Roof

Perhaps the greatest strength left in the music business these days, and the major labels in particular, is their catalogs of recordings and on the reissue side of the business, no one has been better at exploiting a catalog and actually creating new releases of older unreleased music than Sony Legacy.

Bruno Putzeys' NCore variant of switch mode (class D) amplifiers, in combination with switch mode power supply, represents significant progress.

If well implemented, Putzey's NCore can be fully adequate for high quality audio, but that is not why it represents significant progress, because a well designed conventional class AB amplifier with conventional power supply can also produce high quality audio at similar power output.

What represents significant progress is that Bruno Putzeys' NCore variant of switch mode amplifiers, in combination with switch mode power supply, can also produce high quality audio at substantially reduced cost, reduced size, and with reduced power consumption, as compared to a conventional class AB amplifier capable of similarly high quality audio at similar power output.

I would suggest comparison of this Bel Canto MPS1 amplifier to a Parasound Halo JC1.

Here is a link to Stereophile's review of the JC1: http://www.stereophile.com/solidpoweramps/774/index.html

The Parasound Halo JC1 sells for less than $5K.

Bel Canto chose a $15K MSRP price point for this MPS1, and by doing that they have failed to deliver the real progress that Putzeys' NCore could and should provide.

Bel Canto's small dealer network in the US will sell a few of these, probably very few, and I suspect this Bel Canto product will soon fade into oblivion. I hope Putzeys' NCore does not fade as quickly.

JRT's picture

I'd like to see Bruno Putzeys' NCore implemented in active loudspeakers, with DSP crossovers, attached to a wired gigabit Ethernet network using Audinate Dante multicast. Dante uses conventional gigabit Ethernet switch and wiring.

The front end of the system could be as simple as a netbook running JRiver and Audinate Dante virtual soundcard. Dante virtual soundcard uses the wired Ethernet port to attach to a dedicated audio Ethernet network. The downstream end would be active loudspeakers, subwoofer(s), etc., also attached to the dedicated wired Ethernet network. In between would be nothing more than a conventional gigabit Ethernet switch and inexpensive cat5e wiring. That would eliminate a lot of the conventional resource hogs, and the majority of the system budget would reside in active loudspeakers. Setup and configuration could be extremely easy.

JRT's picture

A system using Dante could begin as a pair of loudspeakers (or even just one) attached to the network, and could be expanded by attaching new speakers to the network and adjusting settings on processing.

Audinate Dante over gigabit Ethernet can provide 16x16 24bit/192kHz (16 bi-directional channels), 32x32 at 24bit/96kHz.

edit: I should mention that I have no affiliation with any of these products or vendors.

In response to JRT's comments, yes indeed nCore represents significant progress, the premium, customized 1200Watt capable module used in the MPS1 is NOT an inexpensive device. Also note that the MPS1 is MUCH MORE than a simple amplifier. Bel Canto has released a new e.One nCore based >500W mono power amp that retails for less than $5K a pair, the REF600M. It does not use the same nCore module as the MPS1 units but it does provide remarkable audio performance and value.

did hear it at CES 2015 paired with Larsen Speakers - the resulting sound was very engaging, musical and easy to sink into. Cool looking to boot!

I have noticed in the last several reviews that Mr. Dudley has done his reviews without his TD124 and only the Garrard 301. I wonder why?

Art Dudley's picture

Hi Volvic—I have tended to lean on one when the other requires work, and for the past several months I've been challenged in my efforts to get the TD 124's plinth just so. I'm getting closer—a good saw comes in handy—and in any event you'll see much more of the 124 beginning in the September and October issues and beyond. Thank you for reading my columns and reviews.
