Tvad, can you briefly explain the impedance issue? The input of my preamp is 100k. The Paradisea output is 800 ohms.
Yep, this is where it all starts! Before I do anything crazy, I'd like to try some different tubes. I haven't used anything other than the stock JAN 5670. I'd also like to experiment with output caps (Obbligato Copper, Mundorf SIO). Generally speaking, I can keep myself amused and engaged with tweaks like this if the unit is good to begin with.
