I haven’t directly compared the two, but will tell you that I’m driving my Quatros with Quicksilver monos, and love the sound.   On Mike Sanders’ recommendation, I chose the Mono 120’s over the V4’s.  He thought they’d be a better match.  Good luck!
Thanks bigboltz what preamp are you using 
Quicksilver amps are awesome.....  Rogue seems like fine equipment , haven't heard one in a while but they are a good value like QS
