Montana SP3 vs. VMPS RM30

Can someone quickly tell me how they compare or differ in terms of tonal balance and overall strengths/weaknesses?

Had the Montana SP2's and the VMPS RM 40's and loved the
SP 2's much more. I wish I never sold them!
Very very musical speaker! I could never get the
RM 40's to sound as good in my room. But they
were the very early version.

Different speakers than what you are asking for but
close as I could come.
I had a chance to buy the Montana and went with VMPS but I have the FF3 SRE, the VMPS might be harder to get right and may be more picky with associated electronics, but that is just my guess.
