Hookup wire for tube amplifier?

Thanks for the explanation about the cap position. You're right. I don't think you can call it a coupling cap unless it is directly in the signal path. I've used Vcaps as output coupling caps and like them. I'm trying out Duelund CAST caps in this position. I will experiment with a little silver wire in my amp. As for my system, it is a work in progress. I will send you some pics when its finished.

How do you like the Duelands? The TFTF V-caps sound good but sometimes I think I hear the teflon. (might be my imagination :)) May try AN copper caps.

I have not had chance to directly compare Duelunds and Vcaps in my amps yet, so can't be sure. But my impression based on using these in other components is that Duelunds are more natural (more realistic timbre of instruments and vocals) without losing fine detail. Vcaps seems to be more detailed, but not as natural as the Duelunds. The Vcaps seems to have a "zing" to the treble. Hard to put into words. People often describe Teflon caps as having its own signature, so you may not be imaging it.

Jetrexpro and Dracule1,

Since there is no consensus on what is "neutral" or "no effect," every comparison is with respect to some other component. I would expect Teflon to be different from other kinds of caps, so in that sense, they have a sound. In one of my linestages, the sound is a touch leaner, quite detailed and fast sounding (the zing to the treble you mention). I like the teflon caps in this application, but, I have no idea if this quality is, in any absolute sense, good or bad. In other gear, I've heard radically different sounding caps sound great, so it appears to be the specific application that matters most.

I am thinking of trying the Duelund CAST caps and inductors in the crossovers of my speakers. This would be easy to do because the crossovers are housed in separate boxes instead of being inside the speaker. I have not been tempted to perform surgery on my current amp and linestage because they were specifically designed and voiced to use some very ancient parts and I think the builder would take out a contract on my life if I tried major alterations (besides, these have transformers on all inputs and outputs and no caps at all in the signal path).

Please keep us posted on your experiments. It seems like you are doing interesting things.

Larryi, in absolute terms you are right, as most of us were not present during the recording session to hear the music live. So we can mostly describe sound of components in relative terms to each other. But to a certain extent, I think we can still infer what should sound correct given our numerous exposure to live music over the years.

I hear many promote use of transformers (input, interstage) over caps because transformers are suppose to give superior sound. However, I have a feeling that proper implementation and choice of top quality caps result in sound just as good as transformers. Just my hunch, nothing more. If anyone has any experience comparing the two approach, I would be very interested in hearing your experience.
