Question on preamp matching with Wright 3.5 2A3 am

Just purchased Wright 3.5 2A3 monblock amps. I also have a Rogue 66 Magnum pre coming for it. I wonder if the two will mate to give enough gain on my 96 db effecient Cain & Cain speakers. Here are the specs. I dont understand specs as far as matching amp/pre and hope someone could help.

3.5 mono's
-----------

Input imped 100K ohms
Input level 2 volts

Rogue pre
----------

output imped 650 ohms
rated output 1.5volts rms
max output - 50V RMS
gain - line stage 23 db
max output 50V rms

I guess the 1.5 v rated output confuses/concerns me on the Rogue. Seems low? The Wright pre's and many others are 2.0 v rated output. Should this concern me?

Thanks,

Bill

Bill,
I answered a similar post on required sensitivity in preamps/amps to drive a system to adequate sound levels. Give it a read...you should be able to sort out the numbers for setup...just sort out whether the numbers you gave are RMS, peak or peak to peak....I would suspect RMS.
