Defy7 or Premier 140?

Thanks for the comments and especially helpful from you, Kw6. I had an Audio Research vtm120 before and I knew what it was like when things were not going well with those tubes. Eight is still easier to manage than twelve, I guest!
Does anyone know how the bias on the Premier140 is done?
Does the 140 sounds as luse and warm as the older models?
Thanks.

Thanks a lot guys for your excellent advice.
