Yes, but is there any sonic difference between xf2 coded tubes and later production xf3 coded tubes?

...Oops, I made a mistake in my question - "xf2 vs xf2", while it shoul read "xf2 vs. xf3 coded tubes".

Best regards,

Thanks a lot!

I had a chance to compare Mullard EL-34 xf2 and xf3 coded tubes in my system. They are very similar, but xf2 tubes sound very uniform, well-focused and soft. In comparison, the xf3-coded tubes are a bit brighter and are a little more forward and thin.

All in all, the difference (if it's not my imagination!) is very subtle.

Best regards,
