Elrog 300B vs Takatsuki 300B tubes

Based on my experience with 2 different pairs of Elrog ER 300bs, break-in is fairly rapid. In my system they were indeed excellent brand new. I'd say 50 hours and they're pretty much burned in. Joe(Snowpro) yes, as excellent as the Takatsuki sounds, the Elrog is fuller and has superior harmonic and tonal richness. The preference could certainly vary I imagine in a different amplifier/system.
Charles,

Dmarkov, I will keep posting. I have EML 45 and RU4, Psvane 101D and 274B replicas, TJ Full Music 300B SE, Elrog 300, and Brimar 5Z4ZY. I have the Takatsuki 273 on the way.

Update. Just tried the Takatsuki 274B on my GG DAC over the weekend. The Elrog 300B and Takatsuki 274B tubes are match made in heaven in the GG. Expensive as hell for these tubes, but the best sound I've heard from the GG DAC by far. I've tried Psvane 101D, EML 45 mesh plate, and TJ Full Music 300B SE output tubes with Psvane 274B replica, Brimar 5Z4GY, Sophia Electric Princess Rigid Plate 274B, and EML 5U4 rectifiers with the GG.

The Takatsuki 274B is the best built and most immaculate rectifier tube I've ever seen. It exudes quality, as it should for a $800 tube. It looked like it came from a silicon wafer chip manufacturing facility.

Brief update,
So far,so good with my replacement Elrog 300bs. Dracule1, I also wish these tubes weren't so expensive so that more people could enjoy them. They are truly sublime in my amp/system. They simply make music.

Hi, Dracule1, Glad it all works out for you. I am going through a long system upgrade/transit. After I am settled, I will try Elrog again. Cheers.
