Inside CH Precision's P1 Phono Preamplifier

Although Swiss-based CH Precision is a relatively young company, its core design team has been involved in high-performance audio for many years.

Their website doesn’t state the company’s age, but something there did provide a hint: Among the design team’s previous activities was work for another Swiss company, Anagram Technologies.

In 2001, in a review of Camelot Technology’s Round Table DVD player, which included an Anagram Technologies DAC, I wrote: “I was so impressed with the sound that I took the Round Table downstairs to my 2-channel audio room and used it there when I wasn’t watching movies.”1

I hadn’t made the connection between Anagram and CH Precision when Raphael Pasche, the latter’s electronics design engineer, visited last fall to install CH Precision’s P1 dual mono phono stage and the optional X1, a discretely regulated, outboard linear power supply that’s claimed to exhibit ultralow levels of noise. The P1 can be ordered as a stereo preamp for $31,000; add $17,000 for the identically sized X1 power supply. Or one mono P1 can be used for each channel, for $55,000 plus $34,000 for two X1s. Expensive stuff.
