they deteriorate in storage.

They even deteriorate if held at less than full voltage, gradually decaying down to the applied voltage.

See manufacturers procedure for testing caps. They reform before carrying out specification testing.

What are your listening experiences with them? Have you done any comparison with passive preamp solution?

This is a fine example of how different people's opinions can be. Just recently I talked to a vintage fan that insisted that 20-30 years old caps in vintage gear that didn't blow up yet are in perfect condition and should not be replaced.*

Have fun, Hannes

*just for the record: I do think that 20+ years old caps should be replaced.

Well everybody knows that old technology is much better than today's.

Should the people clone your old Threshold gear then

Would be a pity for your extraordinarily nice recent amps

Have fun, Hannes

Transformer coupling/volume control seems to be a rather old technology, yet to many folks it sounds superior (I wish I could try it)...

What's the lesser of two evils, 10k pot or 50k pot?

ooh - I got this one. A 50K pot would increase your input impedance (which is a good thing) over a 10K pot. The higher the input impedance of the buffer, the less current (and fewer watts) your source has to put out, thus making the preamp easier for the source to drive.


Oh, and thanks everyone for all your replies about the capacitors earlier.

I too was wondering about using a TVC with the buffer (as I've already got a TVC). So yes, I will go for it

Bring on those PCBs Mr P
