I fell in love with the Leben Hi-Fi electronics back in February of 2007 when I wrote an article about the Leben CS600 integrated amplifier for 6Moons.

I ended up buying the review unit (the ultimate recommendation) and have been using it nearly every day in my second system, which is in a small “BBC-sized” listening room that works best for my Harbeth Super HL5 monitors, and makes for a great system for listening to music or for watching movies.

One of the great things about the Leben CS600 is its ability to use a variety of vacuum tubes, which makes it extremely flexible, and a lot of fun to experiment with. I get a lot of e-mails asking about vacuum tube settings for various tube types, so I thought I’d go ahead and post the settings table as a resource.

Be sure to let me know if you find a tube type you really like for the CS600, and I’ll let others know via this blog as a way to share the fun.

Below is the tube settings table for the CS-660P from the Leben web site (the 'O' indicates the correct switch position for a particular tube):

Here's my table for the CS-660P that says the same thing in a different format, which I tried to make a little easier to understand than the Leben website table above:
