KS-1030 lacks bass - Any suggestions?
I am using the KS-1030 between my Marantz cd-67se player and an Audio Research LS-15 pre-amp (which feeds into an Audio Research 100.2 via a balanced Audioquest Opal x3 cable). I really like the crystal clarity and soundstage depth I get from the KS-1030, but it lacks the bass extension that I got when using a Monster 950i cable. I am partial to silver cables because of the high resolution. Any suggestions for a cable that will be ultra clear at the high end and give me additional bass extension?
