A (SOLID STATE):

Accuphase A-300 monoblock: $51,900/pair
"The more I listened to the A-300 monoblocks, the more I wanted to listen," wrote JVS about his time with a pair of these powerful amplifiers. (It is specified as delivering 125W into 8 ohms, 250W into 4 ohms, 500W into 2 ohms, and 1000W into 1 ohm.) The MOSFET output operates in class-A up to 125W into 8 ohms, 62.5W into 4 ohms, and 31.25W into 2 ohms. The A-300 has both balanced and unbalanced inputs; the gain and XLR polarity can be adjusted; and an operation-mode switch facilitates bridging and…

ampsandsound Bigger Ben: $5600
This single-input, single-ended, triode-wired, no-negative-feedback tube amplifier drives both loudspeakers and headphones. It offers approximately 8Wpc into 8 ohms and 5Wpc into 32 ohms (when equipped with a solid state rectifier and KT88 output tubes). With 6L6GC output tubes, when it maxes out at 3Wpc, the Bigger Ben powered Zu Soul Supreme speakers "to greater levels of transient and timbral exactitude . . . than most any other amp I've tried," wrote HR. With DeVore Orangutan O/93s, HR found the Ben every bit as…

By audio show standards, it is small, with only about 50 rooms. It is possible to demo all the systems at the show over the course of its three-day run. The show is organized by the same team that puts on the Capital Audiofest and Pacific Audio Fest, meaning there’s experience and a proven track record behind this new show.

I attended Capital Audiofest in November 2023. There’s a lot in common in terms of the exhibitor list and…

JL Audio CR-1: $3500
The CR-1 crossover has continuously variable high- and low-pass filters built around two banks of precision Linkwitz-Riley filters that can be set for 12 or 24dB/octave via. Front panel switch. Upon encountering the CR-1, LG "wondered where it had been all [his] life;" he's been using it ever since. "It's beautifully made, sonically transparent, performs a critical role in the optimal setup of subwoofrs, and has ergonomic bypass and mute functions that let you immediately hear the sonic iprovements of good bass management…

Audeze LCD-5: $4500
The open-back LCD-5 is the successor to Audeze's well-regarded LCD-4 and, like its predecessor, uses planar-magnetic drive units, which feature proprietary, single-sided Fluxor neodymium N50 magnet arrays and a voice-coil concept called Parallel Uniforce. The idea is to vary the width of the conductor to match, or counter, variations in the magnetic flux to achieve uniform force across the membrane. The 90mm diaphragm is just 0.5 microns thick…

Channel D Pure Music software: $129
Pure Music (Mac only) can play sampling rates of up to twice the 192kHz limit of Amarra and Decibel. Like those programs, Pure Music (Mac only) offers memory play, automatic sampling-rate changes, and full compatibility with native FLAC files and in its latest version, DSD files. Going from iTunes to Pure Music, the sonic improvement was modest but worthwhile, with cleaner trebles and improved pitch certainty. Compared with the less expensive Decibel, however, Pure Music lacked some openness and clarity, decided AD. Using Pure…

Analysis Plus Silver Apex Interconnects: $1219.99 (1m pair)
The Analysis Plus Silver Apex uses as its conductor an oxygen-free copper "stabilizing strand" covered with pure silver, in an arrangement the manufacturer describes, somewhat elliptically (haw) as "a hollow oval cable inside a hollow oval cable inside a hollow oval cable," said to be double shielded and thus quiet. And MF found it to be so: In his words, the Silver Apex is "highly recommended!" (Vol.42 No.5)
