Then there were 2

Do not underestimate the Rogue Stereo 100.  It is extremely "clean" with a low noise floor, very good detail and articulation.  Although it is a tube amp, it is not overly warm and is definitely not "diffuse".  I had one paired with Sonus Faber Amati tradition speakers and it was extremely good.  I traded it for the Rogue Apollo Dark Monos which are truly spectacular.  (Primary reason for trade was I felt I needed the extra power and wanted to make the next step in terms of articulation, lower still noise floor, etc.) Rogue is a quiet company. Mark Obrien is a genius in design and is nearly always available by phone to answer questions, discuss the components, etc. Fantastic support.

@craig I own an RP7 so I know how accessible Mark and Nick are. Very good company to deal with. I find their stuff a little to much like solid state, i am getting used to it. I did demo the QS and a VTL in my system and it was very good.

@elliot I am using my own 2 way speakers two MW16P and TW29R Satori drivers. Room is 14x22x7

Are you sure the M120 is not available? Did Mike tell you that?

rogue might be quite good but for my dollar i would go arc if the cost is not a deterrent

One thing to note if using the RP7 as a pre, (from Stereophile's measurements):

" As a result of the increased output impedance at low frequencies, the RP-7's response drastically rolled off below 400Hz into 600 ohms, reaching –3dB at 200Hz (fig.1, cyan and magenta traces). The RP-7 should not be used with power amplifiers having an input impedance much below 30k ohms. Into 100k ohms, however, the RP-7 offers a flat, wide-bandwidth response with an upper –3dB frequency of 170kHz"

Keep in mind the input impedence of the power amp you will be using with it.  I have an RP7 and a Stereo100 and the match is lovely, as it should be with the same brand.
