Thank you for the quick reply. Much appreciated. I will let them burn in for a while to see if anything changes. Will report here any findings. I replaced the 6080's with Gold Lion KT88 to try something similar to your combo. Still on the bright side, but a bit more bass. Sounds very nice...

Hello Shafat, Today I got my first pair of Sylvania 6F8Gs (not VT99s) and they sound pretty nice as drivers with Thomson 6080s as power tubes. I see why you like them. The question I have for you is: are your 6F8Gs also noisy? For me, if the music is off, the background hiss/hum is quite...

I did not try them yet with the Utopia. Since I pulled them out a few weeks ago, the PSVane CV181-T MKII and the Svetlana 6AS7s did not make it back in the amp. If you have a couple of days, I can give them a try and let you know. If you have any challenging music tracks in mind let me know and...

I have tried several Focal headphones and among them is the Utopia 2022. The Utopia is nothing short of unbelievable on the Euforia EVO. The sound stage is wide open, instrument separation and detail are amazing. Not sure why I am using my other headphones anymore... :) I will only have the...

One more general question: When using 4 tubes, all the same in the amp, can they be matched in pairs - left and right - and not necessarily matched as quads? I am asking because it may be better to buy pairs to try in combination with pairs of a different tube and not necessarily buy a quad...

Thank you for all this good information. It is greatly appreciated. I tend to like things on the warm side. I will see if Westinghouse tubes are available to give them a try. Currently, I have KT88s as drivers and Thomson 6080s as power tubes. All good. In some ways I prefer this to 4xKT88s...

Great. Thank you. I hope to try the 6F8Gs soon. Right now I found Tungsol NOS and they should be ok, but will see what else is available. Did you get the Sylvania VT99s matched? That amp looks sharp... :-) Anybody has tried the new issue Telefunken KT88s or EL34s in the Euforia? Any sound...

Ok. Thank you. I thought it was the other way around (drivers are easier to roll than power tubes) because based on the datasheet, the 6AS7 heater current is 2.5A when for most of the replacements like 6L6 is 0.9A, KT88 is 1.6A, etc. The 6SN7s seem to have lower electrical characteristics...

Thank you for your help. Yes, the typical 6L6 to 6SN7 adapter probably will not work because the 6384 pins are different than 6L6. I was wondering if anybody has any experience with how the 6384 would sound in the Euforia. If it is just 'meh' then it may not be worth it to try. I do not have...

Hello everyone. I am new to this forum, but the amount of information here is just amazing. Thank you all for sharing your experience. I have a question about the Bendix 6384 tube. I did not find much in this forum or online about using this tube in the Euforia. The Bendix 6384 is a 6L6...
