I confirm that my favourite pair is the Psvane CV181T2 / Tung Sol 5998. However, these are not cheap tubes, I paid for the Psvane pair around 200 EUR and for the 5998 pair around 240 EUR. Maybe in US the prices are lower but in Europe the situation is different. What you can find at a smaller price, and they are also very good tubes, are Tung Sol 7236 as powers and Siemens C3g as drivers, but for the last ones you need adapters from ebay.
And some pictures, because, as always, a pictures makes as 1000 words and I really like the look of these tubes.
These are Psvane CV181T2 with Tung Sol 5998:
These are Siemens C3g with Tung Sol 7236.
Other options would be Foton 6H8C produced in 50s or EL12N, but I guess now the best pairing of EL tubes is the EL11 / EL39 and other EL tubes are not regarded as good as before.
About these types the guys from the Euforia thread know more than me. I remained stucked in my combo for almost 2 years and could not find anything better to me. Of course, this is a matter of taste, of the rest of the line used (DAC, cables, source), a matter of differences between Elise / Euforia sound signature and last but not least the genre and music types you listen. Maybe I will try a combo of EL11/EL39 in the future, but there is no hurry, as you said patience is a virtue in this hobby.
I listen 90% of my time to rock music, and one of my biggest problems in choosing tube pairings are the Hi-Hat and cymbals, heavily used in fast passages of this genre which sound unclear or grainy on several pairings. Even several types of interconnect cables are warming too much or making these sound dull, so yes, these are killing me and make me always refuse several tube pairings.
