What a Difference a Tube Makes

When I saw the Escalante Design Fremont speaker at HE 2007, I was mightily impressed with their neutrality and precise bass. Fast forward to CES 2008, and things were different. While the midrange and upper frequencies were still sublime, the switch to KR Audio tube monoblocks, from the VTL Reference S-400 stereo amplifier were a mistake as for all of KR's other virtues, bass control was not one of them. Still, one of the better sounds at the show.
