Coincident Technology Dynamo 34SE MKIII

Just acquired the latest iteration of the Dynamo 34SE.Looking to share opinions on tubing and cabling with fellow owners.
@markwatkiss Congrats on your new amp! I also have an EL34 stereo amp running Gold Lion KT77's and an RCA rectifier. Good tubes,  I hope your amp is everything you were hoping. Looking forward to your impressions and happy listening!
The MKII version of that amp seems like a cool thing...I was on the fence between one of those and the Dennis Had amp I actually bought, but Had's amps are somewhat less available or at least rarely available anyway so there's that. Also, I currently prefer the Tung Sol 7581As over anything else I've tried in this amp including the excellent GL KT77s.
Have seen your comments in another thread  where you referenced the Tung Sols.Gonna get some,price is right.
When I hear (literally) how good many new tubes are, and how inexpensive they are relative to certain more "precious" vintage (or Chinese) ones, It makes me glad they exist. And yeah, a pair of 7581As are fairly inexpensive...I bought mine from "local" (MA) dealer Viva...another cool tube company.
@markwatkiss you are successfully using KT77s?  The manual states not to use different tubes.  Where did you purchase your Tungsols?
