Glad you like these tubes...and yes, you MUST also try the 6HM5s on your MK111, EF95 setting - an even bigger WOW! (Please see below...).
Before I fly off into dble triode land, final reflections on the 6HM5s ( Ei Yugoslavia). Have just had a minor shock after burning in my second pair...they are from the same batch of 100 tubes (ebayer tachonz, Serbia) with identical codes, and where the first were amazing, but with a slightly lighter bass kick than some others we have all(?) tried up until now - not counting double triodes, that is - the bass on this second pair SURPASSES all those I have known. I could not believe my ears... how could this be? This just goes to prove once and for all that so much of what we receive from our tubes is down to LUCK OF THE DRAW!..Another good reason to buy more than just one pair at a time?
Also had final confirmation that so often we have no surefire certainty re the true origins of a tube, via a statement/admission on youtube links to 2 videos on tube manufacture at Ei Yugoslavia (posted on the Serbian tachonz site), viz : Ei even put on other peoples' codes so 'they' can be sure of the quality! So once 'Yugoslavia' - or similar - has worn off/been removed (who said that?!) the code would have you thinking otherwise...food for thought?
Happy (lottery?) rolling everyone!
