The CA- 300 could present weakness in the bass as the transistors used in that model heated up. The Ca-301 did not display that trait.
Classe ca 301 is the low end weak.
This unit seems to be build like a brute powerhouse yet I have heard a few reviewers that claim weak bass does anyone own this unit, I am considering purchasing it or a bat vk-500 my system is b&w 804 bryston bp 25 sony scd 1. other considerations would be threshold t 400 my price range is $2200 max.
