I tweaked several high-end for me & for mine friends:
CD transports: Teac P700, CEC TL-1, etc
Tube amps: Jadis JA80
Pre amps changing volume control for stepped attenuators, output caps, etc
So is a long way do it & learned how sounds each component depending where used.
I'm not in competition with commercial products, here in our DIY world exist the pleasure to share, learn & enjoy with all the community & that's it's for me same important than do & very good phono, if I know you before for sure I saved a lot of money buying commercial products.

You have lucky: you have a clear idea what do you want, a lot of people don't know what he want's & spends a lot of money looking for.

Merlin,
I meant my comment to be a compliment to your pursuit of excellence. This is certainly a worthy circuit to invest time and effort into.

Hi Merlin

I am sure it was money well spent !!!

I really apreciate your subjective impressions about different components.... Would you please replace the output caps and let us know the outcome before you go for the interstage ?

I have bigger batches (200 off each) of 2sk170bl and 2sj109bl. So far I have not found any outside grade range.

It could be the factory mislabelled or mixed some batches and gave special prices to some vendors?. Don't know, excluding any error during measuring of course. If they are genuine, is not bad that Dual Triode got some strong ones too. DT, can you photo some on macro so we can see the labelling and if it looks genuine? You used the Ameter method with no drop resistor, right? What is the tolerance of those Ameters?
