Choice of tube amp?


I`ve auditioned some tube poweramps lately, the Rogue Zeus and the VTL S-400. This has left me contemplating a change from SS to tube power amplification.
My system consists of: APL Hifi NWO-2 cd/tube preamp, Pass Labs X350.5 and Martin Logan Summit. The APL and Summits are here to stay :) The Pass is up for discussion :) The Pass, in my setup, is a little dry sounding and doesn`t involve me as much as I know the APL and Summits are capable of. I`ve researched a little more than Rogue and VTL. I`ve been talking to VAC, Audio Valve, Wolcott, CJ and Cary. Any suggestions? And how they will compare to the Pass in my setup? If you feel my question is dumb or that you need more information, just tell me :)

Ali: My Summits have been played for thousands of hours, daily since last autumn :) I used 4 months on placement and I have specially made diffusors from Svanå Miljøakustik www.diffusor.com to control the backwave of the panels which are dialed in to perfection :) I`ve also vacuumed them as recommended by ML. So I started this thread to get tips as I`ve run out of choices with my systems components as it is. Moscode is noted, going to check`em out. I`ve also talked to Mick Maloney of Supratek, his new Malbecs are meant to drive stators and ribbons :)
As of now I`m very interested in the new Supratek 100 watters, Wolcott 120s and 240s, Vac Phi 300 and Rogue Zeus. Anyone here own or have any experiences with these amps regarding electrostats or have an insight to their sonic signature?
If you are running ESLs it is the nature of the technology that you will have to run tubes for best results. ML has set up the speakers at a low impedance in an attempt to make them work with transistors, but it is only half successful as you still deal with a dry coloration that is inescapable with most transistor amps due to the characteristics of the speaker (including the impedance curve).

The way you drive the speaker with tubes is to use an outboard device called the ZERO. This is an autoformer that is set up to allow a tube amp to be optimally loaded while at the same time being able to drive a very low impedance load. It would be nice if ML offered a higher impedance tap so that both tubes and transistors could be used...
Ya that zeus is a killer. I have a review on that amp from hifi choice i can fax
I don`have access to any fax as I`m on holiday in the middle of nowhere in Norway :( But I`ve read great things about the Zeus too, impressive specs for the money. Here in Norway it costs $12k
