Pass Laboratories XP-30 line preamplifier

It was the strangest thing. In the fall of 2008 I was comparing Ayre Acoustics' then-new KX-R line preamplifier with no preamplifier at all—I was feeding the power amplifier directly with the output of the Logitech Transporter D/A processor. (Levels were matched for the comparisons, of course, made possible by the fact that the Transporter has a digital-domain volume control.) Being a rational being, I knew that the active circuitry of a preamplifier, as well as the extra socketry and cables, would be less transparent to the audio signal than a single piece of wire. I wanted to determine by how much the Ayre preamp fell short of that standard.

Ypsilon Aelius monoblock power amplifier

I knew nothing of Ypsilon when I first saw its products in a room at an overseas audio show. Even though the speakers in this system were complete unknowns, I was convinced that it was the electronics that were responsible for the magical balance of what I was hearing.

There's No Business Without Show Business

Cole Porter: An All-Star Tribute (DVD, VAI) includes outtakes of the great Ethel Merman filming for TV, in 1960, a performance of Irving Berlin's "Alexander's Ragtime Band."

Passion of the Hi-Fi: Part II - Dimensions

At the end of April, it will be time to renew the lease on my quaint Kensington duplex. Over the past three years, a cast of typical New Yorkers rotated residency within these plaster walls: stand-up comedians, chefs, and real-estate agents; art handlers and opera singers; venue managers and musicians. Claiming residential seniority over this home of interchanging misfits, it was time to stake claim on the room my system most deserved.

News Flash: Oppo now plays DSD files

There has been a lot of buzz lately generated by show demonstrations of DSD recordings played directly from files and as the opportunity to download DSD files is expanding. The reactions of our writers have ranged from "impressive," to an "epiphany," to my own delight reported in the upcoming May issue of Stereophile. The hardware used has been mostly professional (Sonoma workstation) or semi-professional (Mytek Stereo 192-DSD) or, at the very least, costly enough for the unconvinced to hesitate. Now, in one fell swoop, Oppo has made this possible at no cost at all for those of us who own an Oppo BDP-103 or BDP-105.
