Mu followers IMLE in most cases don't drive low impedances very well as compared to say a properly trimmed white cathode follower (WCF) or even SRPP - A properly designed WCF is inherently PP and the SRPP if designed to match the headphone impedance range will also work in PP. Mu followers work great for voltage gain in applications where the load impedance is relatively high.

I drive 32 ohm and lower impedances quite effectively with a pair of 5842 in a WCF - you only need a few mW typically for ear splitting levels with most headphones.

You need to choose a topology designed to deliver power to low impedance loads, the mu follower is great for providing voltage gain, not quite as good providing high current to a load.

I would think the 6N6P would be ideal in a WCF..

Sorry no chokes available here.

My SRPP was dead quiet.

That's because SRPPs rock, and you are a splitter for thinking of using anything else

my wife who listened to my design thought that too. gave her goosebums cuz mark anthony was so sureal.

spent days tweaking it to see which gave the best sound.

not sure on the dn2540 on the upper cathode or resister split(broskies idea), is best yet.

No. Apparently, neither can his biological father (though I'll admit to total ignorance of their music- I'm very pop-averse).
