Snopro, how many hours did you have on both pair of tubes when you compared them?
The reason I am asking is that it's crucial.
Takatsuki requires 150 hours of burn in. 100 hours minimum from my own experience with many pairs of these tubes in various systems. Until 100 hours they could be a hit or miss. When they are fresh they can even sound like 200 dollar tubes, nothing special. I'd say 150 hours is a must for any critical listening or comparison to other tubes.
I've asked about Elrog's burn time previously but I don't have an answer at the moment. Several people reported they sound good right from the start. But from all my experience with various 300B tubes all of them require burn in. PSVANE T2 requires 300 hours before critical listening or comparison to other tubes, Takatsuki - 150 hours. Elrogs probably some time as well. TJ Full Music SE may sound nothing special until 60-70 hours but full break in is longer. I don't believe Elrog has 0 hours to be broken in. I would give it 150 hours to be fair.
Also, amps that have manual bias, like one of my amps, should be biased for any new tube installed otherwise sound comparison doesn't make sense.
