Audio Research SP9 MKII
Hello
Found two ARC SP9's for sale. The first is the MKII with 6h23p-eb Russian 6922 tubes
the second was a SP9 that was sent back to ARC and upgraded to the MKII, it has 2-6922 Sovtek Tubes installed .
Question, given they are both about the same price should which one would be the best one to purchase?
