Back into the setup jig went the cherry LP12. I stripped it to the plinth once again, then removed the platter bearing from the stock Linn subchassis. (No, I couldn't find the red rubber cap meant to seal the bearing well; yes, I spilled some of the oil; yes, I was wearing off-white trousers at the time. Much hilarity ensued.) The Vector Link kit came with a nice set of machined aluminum rings that are adaptable to either Linn's Cirkus or pre-Cirkus bearings, and are intended to safely and evenly distribute the torque of the mounting bolts. The remarkably light subchassis combines a balsa…
Older audiophiles remember the splash NAD made in the late 1970s with the introduction of their 3020 integrated amplifier ($175). Ridiculously cheap, it looked graceful and sounded warm, inviting, and holographic. Removable jumpers between the 3020's sections permitted enthusiasts to determine whether the magic resided in its preamp, its power amp, or in some synergy of both.
In the opinion of most listeners, it was both. But while the 3020's relatively low-powered amplifier (conservatively rated at 20Wpc into 8 ohms) limited it to driving small, efficient loudspeakers, its…
NAD's PowerDrive circuit continually monitors output current and adjusts the power-supply voltage rails to maximize the dynamic power sent to the speakers. According to NAD, PowerDrive makes the M3 sound far more powerful than its rated 180Wpc. (For a detailed explanation of PowerDrive, see the sidebar "What Is PowerDrive?," in Jim Austin's review of NAD's C 372 integrated amplifier in the October 2006 Stereophile.)
The power-amp circuit uses a wideband, current-mode, class-A voltage amplifier and an NAD-patented current-amp output stage with small amounts of feedback to help deliver…

Sidebar 3: Measurements
As usual, I preconditioned the NAD M3 by running it at one-third its specified power into 8 ohms for one hour with both channels driven. While the measured percentage of THD+noise remained constant throughout this period, at a low 0.0035%, the chassis got almost too hot to touch, and the side-mounted heatsinks definitely so. Measured at its speaker terminals, the M3 offered a maximum voltage gain of 39.2dB into 8 ohms for both balanced and unbalanced input signals. With the volume control set to "0.0dB," the overall voltage gain was 29.2dB. This was also the gain…
The one thing I've liked about designer Mike Creek of Creek Audio as much as his design talent is his predictability. I've been following his integrated-amplifier designs for nearly 20 years now, having reviewed, in sequence, the CAS4140s2 (for another magazine), the 4240SE (Stereophile, December 1995, Vol.18 No.12), and the 5350SE (March 2001, Vol.24 No.3). In each case, I was sufficiently impressed with the review sample that I bought it and made it my new reference in my second, affordable system. The predictable part comes from Creek's traditional nomenclature: an "s2" or "SE" (Special…
The Sound
I can't comment on the timbral characteristics of the Creek Destiny because, across the entire frequency spectrum, I heard not a single deviation from neutrality—this is the least colored component I've ever reviewed. Here are its strengths:
I can't comment on the timbral characteristics of the Creek Destiny because, across the entire frequency spectrum, I heard not a single deviation from neutrality—this is the least colored component I've ever reviewed. Here are its strengths:
• pristine, extended, and detailed high frequencies with no trace of hardness, and a purity and delicacy that reminded me more of the pricier Jeff Rowland Design Group products than of older Creek designs; appearing in my listening notes many times: "Clean! Clean! Clean!"
• an organic rendering of low-level dynamic articulation…
