Amps make a clear difference especially very capable ones. I use my 2Stepdance and most recently my ICAN. Both have thrown SQ into overdrive for me and now I want a portable one that I can lug around either with my X3 or DX90..
I used to own the E11 and that was actually very capable for being a cheaper amp. I am looking forward to the E11K,.
Will a cheaper amp make any diference for dx90 though?
