I may not have many tube rolling experience but the first tube i have for lyr is cca pre 1965 ( not the 1958 ish)
Powering the hd800( dhc complement fusion cable ) with those tubes gives me music that touches my heart thus
i dont find it necessary to change to my other tubes which are nos cca post 1965 & e88cc mullard michum or amperex e88cc SQ.
i am not that much into classical but i like to hear good voices like celine dion, adele , britney, christina aguilera and yanni concert.
what important to me is the music must have emotion & be able to connect to me regardless it coming from voices or music instruments.
