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.
Follow Ups:
But I am afraid thats where I fall down. I can solder, it's not the best, but whenever I get near a piece of equipment, my nerve goes and I drop the iron and run away screaming.Shame as I believe alot of kit can be tweaked slightly.
Continue the fiddling,
Or you could upgrade the resistors to Dale Vishays or other highly resolving metal film types.
Removing it probably results in an impedance of perhaps 1 megohm and lots of RFI/EMI sensitivity.
On some systems the resistors that control pumping really muck up the sound. If any resistor is in the signal path I would use a Dale Vishay or at least a Holco. This should be a big sound improvement.
it is not in the signal path, IE in series.
Since when is a shunt component not in the signal path?
Garth,I feel that the paradigm of the signal path being some kind of "pipe" from input terminals to output terminals is in contradiction to the most elementary understanding of how electronic circuits work.
This is one of my pet peeves: I have a little rant on my site on the subject.
