Matson: The Beatles in Mono LP box set?

Berkowitz: I grew up in Boston, and I knew a guy in Boston, Jeff Jones. Jeff and I worked together at Columbia Records as marketing directors; Jeff was the first head of Legacy. Jeff and I had 10 years of making records together. After a number of years, he left and became the head of Apple Records. In 2009, he sent me the stereo Beatles LP box. When I received them, I wanted to hear the second side of Abbey Road. First, I took out my original 1969 UK copy. It has ticks and pops, and I'm thinking, God this sounds great! Then I put on the…

Jim Austin to the rescue. To his query, "How would you like to review a tube preamp from Canor, of Slovakia?" I answered with an enthusiastic "yes!"

In addition to the exciting prospect of reviewing the first tubed preamplifier to come my way in a long time, hearing the Canor Hyperion P1 preamplifier ($12,500) in my system would enable me to get a handle on the sound of gear I'd only encountered once, at High End Munich…

The Hyperion P1 arrived with its four 6922 tubes already in place. To prepare it for use, I employed a special tool (included in the box) to remove the 10 screws that fasten its top to the rest of its chassis. After carefully removing the top, I inserted the two 6H30PI tubes into their prescribed sockets. To ensure correct positioning, Bierfeldt had labeled both the tube sockets and the protective bubble wrap surrounding those tubes "1" and "2."

To replace the cover, I had to surmount two minor challenges: setting it in place without pinching fingers and lining up the screw holes…

When I unboxed the Canor Hyperion P1 preamplifier, the four 6922 tubes, two for each channel, were installed, but the 6H30PI dual-triode tubes, labeled "1" and "2," were packed separately. I carefully installed these tubes in the sockets that corresponded to their numbers and checked that the 6922 tubes were correctly seated. I performed a complete set of tests with my Audio Precision SYS2722 system then repeated some of the testing with the magazine's APx500 analyzer.

I immediately encountered a problem in that there was no output from the right channel,…

These days, amplifier design often emphasizes efficiency. Class-D amps in particular have come a long way. Many are terrific, and they're…

Secondo piatto
Most audio components' capacitors are soldered out of sight, neatly concealed inside the casework. Not the Legacy. Mounted in the silver center bay that runs lengthwise across the top of the amp are six custom capacitors—"pretty maids all in a row," my brain quipped (footnote 6). Each is Ferrari-red and looks like a D-cell that's been hitting the gym. These caps are made in Italy by Itelcond. Along with those logo-shaped heat fins, they've become part of the Pathos look. The company sources smaller, interior capacitors from Italy's ICEL. The input and speaker…
