Just so you all know, the reason its a bit "untidy" is that the entire thing is potted in silicon, so it had to be dug out before working on it. As said, I replaced the ceramics without thought, as I rarely find they deserve a place in the audio chain. The FKP I agree tend to be warm, but IMHO thats a good thing when combined with a unit what was a little hard sounding to my ears to start. The oscons were a experiment, In the past I would have used little black gates, and it possible I still will, see how Marco gets on, but it was the low noise character that I was most interested in.

TBH, it is noisier than I would have hoped for anyway, I have a thought to try something with a couple of 2sk369 in each chan.
