While many audiophiles swear by loading networks, Linn's reasons for avoiding them are compelling. Linn claims the switches used in most…

But Linn isn't selling packaged air; they saw the future coming a long time ago and constructed their Glasgow facility to take advantage of automation and high-quality surface-mount construction. Despite its light weight and empty real estate, there's a lot of technology packed into the Linto. Besides, as Linn points out, a square centimeter of circuit area can pick up more signal as interference than a moving-coil cartridge generates as music.
The Linn was also superlative in its re-creation of bass. It had remarkable extension and definition. If you believe the bass region is the foundation upon which musical cathedrals are built, then the Linto is your meat. I've never heard Ron Carter's tone possess more heft and character than it did when I played Herbie Hancock's Maiden Voyage (Blue Note ST-46339) through the Linto. He isn't playing a really mellow-sounding instrument on the album—with some phono sections, I would have wondered whether this perception was colored by the preamp's limitations or whether I was hearing the sound…

Measurements
As Wes Phillips found, the Linn Linto was astonishingly quiet, with an A-weighted S/N ratio (ref. 500uV input at 1kHz) of 85.3dB. Unweighted, with a broad measurement bandwidth of 10Hz to 500kHz, the S/N ratio dropped to 66.5dB, which is still excellent. Its voltage gain in the high setting (the only one I measured) was 62dB rather than the specified 64dB, probably due to the 25 ohm source impedance of the Audio Precision System One. The difference is negligible.

I had a wonderful audio moment the other night. It was late in the evening, after a long day. I was standing in the middle of my makeshift listening room—Trish's dining room—and in spite of the fact that we were moving in just a few weeks, I'd just unpacked and set up my combo of VPI TNT Mk.V-HR turntable and tonearm with Grado Statement cartridge and dug a box of LPs out of the stacks in the garage. I cued up Dave Brubeck's Time Out (Columbia/Classic CS 8192), and the first notes of "Blue Rondo à la Turk" froze me in my tracks.
The music hadn't just started, it had come to life…
The Signature looks gorgeous. Its faceplate is a thick, softly sculpted slab of aluminum finished in a flawless, glossy black embedded with gold flecks that beautifully complement the heavy, gold-plated knobs. There are large knobs for Input Selection and Volume, flanked by two smaller ones on each end: Mute and On/Off on the right, Tape Monitor and Cinema/Direct on the left. The Cinema input provides a fixed-gain path from input to output, allowing a user to send the front channels of a home theater or surround system through the main audio circuit, but controlling the level with a…
Midway through the Saint-Saëns Bacchanale is a delicate exchange between the woodwinds and French horn. With the VAC, it wasn't simply point/counterpoint, but more like a tennis match, the lines bouncing back and forth between the instruments, their location and interaction with the surrounding space and hall boundaries transcribing an arc through the air above the orchestra. This particular passage was especially captivating because the span so beautifully described was truly three-dimensional, traveling not only laterally but also front to back and vertically, describing the relative…

I first looked at the VAC Renaissance Signature Mk.II's phono stage, taking the output signal from the tape-out jacks. The input impedance and voltage gain at 1kHz were 47k ohms and 43.7dB (MM setting) and 365 ohms and 64dB (MC). The RIAA error, shown in fig.1, is distinguished by a double-humped response curve with an upper-midrange valley some 0.5dB deep. This covers a wide enough frequency range to be audible. The response is sensibly curtailed above and below the audioband, reaching -3dB ref. 1kHz at 11Hz and 76kHz. Channel separation (fig.2) is good rather…
