Hi all,I recently changed the interstage capacitor (5uF) and its bypass capacitor (0.1 uF) of my ARC PH3 to Mundorf Silver Gold capacitors. Also, the circuit trace of about 20 cm connecting the output of the unit to the final element, a resistor, was upgraded with 24 AWG Jenna Labs cabling, changing termination to WBT Next Gen connectors.
The overall process took about 2 hours with careful planning and it is very much worth the effort. This changed the already beautiful device to a higher league on soundstaging, and treble performance, keeping all the good features.
Strongly recommended.
Cheers.

- If it is in the signal path it is setting the impedance, if it is to ground it is eliminating woofer pumping. - tubesforever 12:31:29 09/09/06 (4)
