6CG7 EH, Matched, Balanced

Actually I was skeptical to change the vintage tubes in a vari-mu stereo mastering compressor but found the unit to sound slightly differently colored between left and right channel. I changed the RCA vintage tubes in the unit used to the EH. I bought the reissued 6cg7 as matched pair and the unit sounds much better balanced and defined straight away. Definitely recommend this tube without any cons so far. Great product. Another hint to critically question the vintage tube hype.
