Is Belles Soloist 3 pre amp compatible with Belles 150A Reference V2 power amp?


Running a Belles Soloist 3 pre amp with Belles 150A Hot Rod power amp for years. Catastrophic failure of power amp.  Replaced with Belles 150A Reference V2 power amp while still using the Soloist 3 pre.
   Is this coupling of an older Belles entry level  pre with a new Belles power amp a mismatch?  I'm sure there is much to be gained with a new Aria pre but is the original Soloist 3 compatible, or is it holding too much back?
