I agree with Trelja on the tradeoff of a good EL-34 tube. I am using NOS Siemens EL-34's (12) in my Cary V12i. This amp also accepts other tubes including KT-88, KT-77, KT-66, or 6550. At the outset I was intent on tube rolling with others besides the EL-34. However, the Siemens NOS made me forget all about that. I'm sure the bass could be better, but its good enough for me and the mid-range and sweetness are exceptional.
