Default My new Head-Amp finished...!

Finally, (pcb have been lying here a long time), a new head-phone-amp is done. It's "QRV-03", one of "P-A" 's constructions, and the second of his, that I built. (First was the QRV-02).

Sound is full, detailed, refined & "airy"...until my wife confiscated it...
No problem, I still have the QRV-02...only problem; I have only one set of Sennheisers

Hi Arne,

nice Head-Amp. Why you don't use a shielded wire for internal wiring? Make a try and use your internal wiring as a chinch inconnect and compare it with a good shielded interconnect. You will be astonished about the difference. It is often usefull to mount the attenuator in the back part of the enclosure an use a a extension rod between attenuator and button at the front panel.

My favorite interconnect is the Voodoo-Cable from

Regards,
Arne

Default thanx

About internal cabling; I use as little shielded cable as possible, rather twisted.
I use good quality silver, or silver-coated cable, always with teflon insulation.
Tried a old interconnect cable internally in my previous amp, but preferred this version.
(BTW, trafo is shielded).

You must like plastic look volume knobs in front of expensive switches.

to Upupa Epops:

what do you want to say? Is your opinion that shielding and good cables (such as teflon or mica isolated solid silver) are nonrelevant?
