Overview
The stock GCPH was an amazing phono preamp that got a strong endorsement from Stereophile magazine. It will accept MC and MM cartridges where you can then adjust the gain and load easily via their rear controls. The gain adjustment knob in the front adjusts the output volume level so you can hook the GCPH directly to an amp if you only run a vinyl source and want to keep the system as minimalist as possible. The previous owner absolutely love it so much he sent it too Parts ConneXion for their $700 upgrade package. The improvements made are listed below;
- 4 x Japanese Takman ½ and 1-watt signal path carbon resistors with gold-plated leads
- 4 x Mur 860 Hexfred ultra-fast soft-recovery rectifying diodes
- 4 x Nichicon ultra-premium 100uf 25v electrolytic capacitors
- 1 sheet of Soundcoat chassis damping material
- 2 pair of premium WBT-0210-Cu direct gold plated over copper body RCA female jacks
- 1 sheet ERS suppression paper to damp EMI/RFI
- 1 foot of DH Labs 18-gauge Revelation Series pure 99.999% silver solid-core input wire with Teflon tape-wrap dielectric
- 4 x EAR small Sorbothane isolation feet to suppress vibration and airborne feedback
- TRT WonderSolder used throughout
Cosmetically, there are some minor scuff marks here and there that are common with use but nothing major. We don’t have the original box but will securely pack it for safe shipping.
