Or you can connect a powered sub as long as its bass is natural and musical. This can provide the needed low-end and preserve the all important midrange. I thought my solid state preamp was bass shy until I connected it to a PSE amp. Wow, the low-end improved tremendously. So sometimes it is not always the preamp's fault.
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!
