I thought I would share some interesting experience.
Though being very satisfied (as much I liked a tad more bass) with my preamp, I thought I'd try what a different tube in the output stage could do. My preamp, a Zanden Model 3000, has effectively one double triode tube (type 5687WB) which is factory-supplied with a Philips JAN 5687WB brand.
I surfed the net and bought for 50 EUR another NOS tube from the Tungsol brand and inserted it in lieu of the Philips one.
I wasn't expecting such a change! In my case for the better, the bass is now exactly where I want it to be, the high is even sweeter and natural. I definitely experience this experiment as if I have been able to extract all there is to get from this excellent preamp (except remote control ).
Enjoy!
