low bass on Audio Research LS27

Hello , the amount of bass depends also on the poweramplifier you are using , if its a ACR , ok the connection can 't be better , but another brand of poweramp you must assure the inputimp of the amp is more than 100KOHM Is it less you will have less bass .I owned
two magic Sphinx PJ 26 mono amps , but they had an inputimp of 600 Ohm , no perfect match , after changing to BAT VK 1000 monoblocks it is a marriage in heaven ( ARC REF 3 preamp )

Thanks folks. About the power amp being a key component, especially for bass management - I agree! That's why I have a Krell FPB400cx - 400 watts of Krell bass. What has been shocking is how big a change in the overall character of the sound the preamp made while the amp remained a constant, and how much of a chameleon the Krell amp was.

Great info on the small delta in performance of the LS27 vs. the Ref 5.
