I just picked up a used Ember (with SC) that came with 4 tubes. I got it to use with the HE-4, but I also just grabbed an HD650 on super sale just to hear it.
Well tried all the tubes I had with the HE-4 and none of them really impressed me. I kept my favorite one in and tried the HD650 (which didn't impress me from the SS amp) and holy cow!! HD650 with Amperex 6DJ8 is really something! I'm starting to get an inkling of what people mean when they talk about synergy in your components.
Anyways, I'm still looking for a good tube to go with my HE-4. I'm looking for something that will tame the highs a bit without really ruining the planar bass. So far, I haven't found that sound. Can anyone maybe suggest something, preferably in a sane price range? Someone suggested a Philips Miniwatt, which turned out to be a $200+ tube. :-/
Oh, for the record, the tubes I tried were the Amperex 6DJ8, generic 6H1n (which is a P in Russian, I guess), generic 6N6P, RCA 12BH7A.
I'm hoping that the SC will give me access to some nice tubes that are maybe less in demand, and therefore cheaper.
EDIT - Read the last 6 pages of this thread and my head is spinning.
