Audio Research I/50

do you sure that after changing to a new tubes there is no an additional break in?

I am sure there IS tube break in, but it is not 600 hours.

A local dealer let me take one home for a few days.  I thought it was great, especially for the price.  I wanted to order one but there's a 2 month+ wait and I have a Leben on order that I have a 5 month wait for.  I was using the ARC as a temporary amp while the Leben was being made. I still may get one once the DAC module comes out in June. They are not auto-bias. You need to flip it over and do it manually as someone already said. That's according to the dealer.

Would love to hear more from your hands on listening session with the i50. I heard one driving Maggie 1.7i briefly and thought it sounded great.
