I believe this Amp now retails for $5995. My point in bringing this up-is it would be nice to make a comparison head to head with the Torii Mk III. After about a year with the III, I am going to see if I can find someone that owns it through (for example) the Audio Society of MN or other means/sites, even if I had to drive a few hours.

I am also surprised that a reviewer site like 6moons or positive feedback has NOT reviewed the Torii Mk III, but both have reviewed this Amplifier.  6moons reviewed the Taboo? Here is hoping for Tone Audio 41 too.

"The $5495 Leben CS-600 is the most powerful Leben integrated at approximately 30 watts. The CS-600 was developed at the insistence of Leben customers who wanted the Leben signature sound in a more powerful integrated amplifier to drive their less sensitive loudspeakers. Hyodo San designed the appearance to be similar to the CS-300X with the intention that this style of appearance would become symbolic of Leben's integrated amplifiers.

The first stage of amplification in the CS-600 uses the twin-triode 6CS7, and a 6CJ3 rectifier provides a slow turn-on of the B-voltage to the power tubes. The CS-600 includes cathode-resistor and plate-voltage switches inside the chassis to optimize it for a variety of different output tubes. For example, with 6L6GC tubes in place, the CS600 provides 32-watts of output, and 28-watts with the EL34. The CS-600 comes stock with 6L6GC output tubes; but 5881, EL34, KT77, 6L6GB, 350B, KT66, KT88, and 6550A can also be used".

Prices always go up right? Demand increase too of course........ .

How long did you have your Torii MK III? How long have you had the Leben CS 600? What do you like best by comparison about the  600?

 All components of a system must be considered as a whole and they must play together to work well together.  I would never expect my Torii to be a perfect math for every speaker.  The Leben, from what I know of it, is being made by a designer that has a clear vision of what he wants his product to be.  So give him credit for the design.  I do not think it is a revolutionary product but well executed nonetheless.  I can see many scenarios where a stiff power supply with feedback would allow greater control with a lot of speakers.  Don't consider this damming praise. The Leben is a beautiful piece.

I couldn't agree more Walt. My tonal balance priorities with my addiction to even order harmonic's with no negative feedback in both Amps I'll be using/Zen Select (2001) and the Torii III....is for me.

Mr. Hyodo is to be admired as is Mr. Deckert.
