Just tried out the new BMax last night. Am very impressed. Could'nt fine just the right tone though until my son came along and started playing leaving both of my hands free to play around (as well as give his opinion . Question for owners. I can't tell much difference in tone between having the pre gain and master in the BMax up high about 7-8 with the PLX 1602 power amp turned down, and the other: pre and master lower about 4-5 with the power amp cranked. Is my ears deaf from sitting in front of the speaker to long? Does anyone hear any differences?
