low bass on Audio Research LS27

I had an LS26 for awhile. It had a magical midrange and lovely open highs, but for me the low bass was not weighty or extended enough (actually it was pretty anemic for my -3db at 28Hz speakers). I replaced the LS26 with a Krell KCT SS pre, and got the bass I wanted, but that magic on vocals is gone and I miss it. How is the bass on the LS27? Do I need to save for a used Ref 5 to get what I want? Thanks for your input!

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 )
