‘Current’ ingangMichael Fremer is zeer overtuigd van de voordelen van phonotrappen met ‘current’ ingang, zoals de CH Precision P1:
“If you’ve got an ultra-low-output MC cartridge or three, the advantages of a current-amplifier phono preamp will become as immediately apparent to you as they did to me when I reviewed the B.M.C. Phono MCCI in the June 2013 issue.
The ultra-low noise floor, freedom from voltage-suppressing loading, and overall tonal neutrality allow the cartridge to fully express itself, for better or worse. I heard that with the B.M.C., and with MR Labs’ VERA 20.
Inherent in current-amplifier phono preamplifiers are an openness, a tonal neutrality, and a background quiet that you should hear, though the result will not be to everyone’s taste—especially those who prefer a warmer, richer sound. However, it’s easy to argue that the place to inject those qualities into the system is at the cartridge and/or loudspeakers themselves.
In any case, via either voltage or current input, the P1 was the quietest phono preamp I’ve heard. Backgrounds were dead “black,” even with the volume well advanced and my ear almost touching the tweeter: I heard only a hint of hiss and zero hum. More important, music had an honesty, clarity, transparency, and rhythmic drive that, in the right systems and for the right ears, will be “the end.” But it won’t be for everyone, and satisfaction using such a no-compromise, honest electronic circuit will certainly depend on the records played.”
“With some LPs, the Ypsilon was more pleasing; with others, my nod went to the P1. I need both! If I ran a Gear Motel—you know, one of those places where audio components check in . . . but they don’t check out—I probably could have both. But I own and love the Ypsilon, and I can’t afford the P1 even at an accommodation price. So back to CH Precision it will go. And I will miss it.”
