I currently own a K701 driven by an O2 amp.
My desire is to upgrade to Stax (either the basic SR2170 or the SR3170). I know the Stax sound. My question is though how large the actual differences between the SR2170 and the higher Lambdas is? Is it a huge step-up or barely noticeable? I do not plan to upgrade to SR007 or SR009 anytime so I am trying to decide where the price/performance sweetspot in the Lambda range is. My musical preferences include Vocal, Jazz, Blues and Classical. Huge bass slam is not important for me. I am mainly after resolution and airy sound. Is it worthwile to choose the larger Lambda set given it has a better amp or is the basic system good enough?
Thanks for your help.
