Wow this is the tube sound ive been looking for on my HD600 !
I was using the Voshkod 6ZH1P-EV which was transparent for a tube amp and sounded technically good but it was missing that fun thick fun treacle detail i wanted.
Ryan1987 recommended the M8100 in a previous before but ive only just got around to ordering and trying it into my Little Dot MK2.
Really thick and goey sound and superb for vocals, Bass has more thump and mids are just so lush. Highly recommended and has put a real grin on my face. Very happy with my modest setup.
E10K as dac > Little Dot MKII with M1800 tubes > Sennheiser HD600 +
All purchased second hand for just a few quid more than buying the HD600 brand new.
