"Piccolo" MC Headamp - $349 ($89 kit/2) 30-day free trial - Order now!
Upgrade to a "Piccolo" from Hagerman Audio Labs!
|
The Piccolo is an active moving coil pre-preamplifier designed to step-up the cartridge signal from
MC to MM levels. Adjustable loading and gain offers optimization for any MC cartridge. The discrete
JFET circuit offers super-quiet and distortion-free operation. Compatible with any MM phonostage.
Power is provided by either 4 internal AA batteries or a 120Vac external supply. The circuit employs
super low-noise matched JFETs in a differential configuration, but tapping only the non-inverting leg for
the output buffer, which can drive long cable runs. Careful attention to layout and wiring eliminate ground
loop problems.
The DIY half-kit version comes with the expensive JFETs pre-installed. It also comes
with hardware specific for proper assembly (3 screws, 3 nuts, 1 LED dome, 1 lock ring, 2 terminals,
2 washers, and 2 caps). The remaining parts will cost you an approximately $70 from DigiKey.

Customer Testimonials
- I think it's a great sounding piece or more accurately, non-sounding, in that is doesn't seem to leave a
sonic footprint.
- The sound is absolutely fantastic. Was using a step-up transformer and the Piccolo eliminated the hum
that was driving me nuts. I am spinning vinyl almost exclusively now.
- Man, I have to tell you that this is by *FAR* the most satisfying kit I've built. The increase in
dynamics and soundstaging I expected are there in spades! HUGE!
