Tube Break-In sound character change


I just spent over $600 on a set (4) of Sophia Electric 300B 2.5v Princess tubes for my Wright Sound Mono 10 amps, but so far much prefer the sound of the much cheaper EH Gold 2A3 tubes. These Sophia tubes have gotten very good reviews on these pages. The question is: how much does the sound character change as the tubes break in? I have only about 4 hours on the new tubes, but so far they sound a little tizzy and less rich than the EH tubes. I'm surprised, because I thought than right out of the box they should have the EH tubes beat. Will they change just a bit, or fairly dramatically with use?

>>You replaced 2A3's with 300B's??? I dont' think break-in is at issue here, but compatibility<<

They are 2.5v 300B's made to replace 2A3's.

Thanks Larry & Eee. I can already hear it is a bit better. As I mentioned, I just thought that out of the box they would be better than what it was replacing... I suppose not.
