Manufacturer's Comment

Editor: I have just read [Ken Nelson's] May 22 letter urging us to consider advertising in Stereophile. I understand that your business is to try to encourage potential advertisers to consider this publication, and I also confirm that you continue to write me in this regard.

I think it is only fair to remind you that we have decided as a policy matter that we do not consider Stereophile a publication to be included among those in which our company advertises. We and our agency are experienced [enough] to know and respect the separation between advertising…

A Record Seven Grammy Nominations for Reference Recordings

"I'm still in shock," Reference Recordings recording engineer Sean Martin blurted out during a conference call with his recording engineer stepfather, Keith O. Johnson. "When Jan Mancuso woke me up at 5:30 or 6 to tell me the news, I couldn't imagine who would be calling so early," was Johnson's follow up.

Reference Recordings and Johnson have been nominated multiple times for Grammys over the years. ("I hate to say how many times I've been nominated for the Engineering Award," quips Johnson, "although I only won it once, in 2010, for Best Engineered Surround Sound on Britten's Young…

PS Audio Lambda CD transport

It's easy for reviewers to become jaded by the high prices of some audio products. We get the products in our listening rooms—albeit temporarily—without having to part with our own money. Consequently, we get enthusiastic about products that offer real breakthroughs without, perhaps, fully considering their cost.

Reviewers should consciously try to avoid this tendency. Although we should report on cost-no-object components, the bulk of our readers want high musical performance at an affordable price. That's why I get most excited about reviewing sensibly priced components that offer sonic…

Beveridge 2SW loudspeaker system

This is an electrostatic column speaker, 6' tall and costing $6000/pair. An integral, fan-cooled amplifier is located in the base (footnote 1). The 2SW is said to cover almost the entire frequency range and is based on a patent, number 3,668,335, issued to manufacturer/designer Harold Beveridge on June 6, 1972. Internal acoustic lenses in front of the electrostatic panels widen the speaker's dispersion: In the Beveridge literature, it says "This 6-foot high device consolidated the entire frequency range into a vertical line source, and uniformly disperses it over a horizontal pattern, 180…

PS Audio Lambda CD transport Review System

Sidebar 1: Review System

I auditioned the Lambda driving PS Audio's new Reference Link digital processor and "preamp" (see review elsewhere in this issue), a Mark Levinson No.30 Reference Digital Processor, and the Meitner IDAT. Digital interconnects included an AudioQuest Optical Pro II glass fiber, and Aural Symphonics and WonderLink coaxial types. My review sample was fitted with ST-type glass fiber, but not with AES/EBU output.

An Audio Research LS2B line-stage drove VTL 225W monoblocks via a 20' run of AudioQuest Lapis. Alternately, the power amplifier was a Mark Levinson No.…

PS Audio Lambda CD transport Measurements

Sidebar 2: Measurements

The four transports held in highest sonic regard (the Mark Levinson No.31, the C.E.C. TL 1, the PS Audio Lambda, and the Proceed PDT 3) all had low jitter. I thought the PS Audio Lambda was slightly better-sounding than the PDT 3——and the Lambda had slightly lower jitter.

Fig.1 is the PS Audio Lambda's jitter spectrum with digital silence (track 4 on the CBS Test CD), the heavy dotted trace is the jitter spectrum when the transport is transmitting a –90dB, 1kHz sinewave, and the lightest (top) trace is made with a 1kHz, 0dB sinewave. The RMS jitter level…
