Mike Elliott is a superior designer, he has been responsible for some of the best and most important audio products around. As far as performance, I suspect that if you just got your amps back that you may have as much as six weeks ahead of you in break in before you hear all that they are capable of. Also, the tubes in those amps are very critical to performance, bet it has stock units in there now. Something to consider after break in. Use up the stock tubes and pile up the hours before investing in NOS. Besides, you will appreciate the NOS stuff because you will have developed a reference.
