It is probably very system dependent. Ked brougt them to my place and when we replaced KR PX 25 / Fivre combo with EML 45 / KR 5u4g RK it was obvious for both of us that in my system it was more resolved , better timbre and better overall musicality in the same time.Funny but the highly touted EML 45 mesh Lampi Anniversary Globes continue to underwhelm me in my systems each time I give them another try
If they wouldn't be that rare and unobtainable, I would have long sold them
But that being said, I still keep them in case I should change systems some time in the future and they should magically do some magic for me all of a sudden
Now with Trios once the upgraded amps stabilise I will roll again my tubes to see how is the synergy in Trio/Rel setup.
