A simple design, but sounds GREAT for the money, $299 retail.

I'm wondering whether the circuit will accept the common AX7 subs (5751, etc.). Have you tried any in your 540?

I haven't tried anything other than 12AX7.  I'm too chicken.

Wouldn't it almost have to be a hybrid, given the output impedance of a small tube like this? OK with me if it sounds and works great. Sure looks good. What did you pay? k701smile.gif

Got it on eBay. New, drop shipped from Rolls. Looks like the sell doesn't have anymore listed.

Anyone well-versed in headphone amplifier design care to comment on what we're seeing here in the design of the HA540?
