Rogue Sphinx v Nakamichi PA 5 MMKII and a preamp


I am trying to decide between used items for around the same price  A Rogue Sphinx V1  with remote verses a Nak PA 5 MK II and maybe an NAD or Rotel preamp with remote.  The integrated would be easy but will it sound better then the separates >  Both can drive my big old Infinity's  but I am guessing the NAK  amp will more current

Umm what  would I replace RS 2.5s with?  Have you ever heard a pair? I have had   Vandersteen, Von Schweikert PSB, Mirage, ADS Energy,Polk Canton and so on.  They all have their strengths but  The 2.5 is better in almost every way.  The Rogue is not doing anything wrong it just sounds a little  veiled and not very vibrant compared to the other gear.
Infinity RS 2.5's??? Up against the new Vandersteen's??? Not a chance in hell......
Well there we have it.
I guess you have had them all  in your home and compared them all side by side so to speak ?  I know I have .   As a matter fact had Vandersteen 2Ce and 2CE sig 3 times. Great speaker but not for all of us.
Each to their own.
We agree to disagree. It's your speakers, your system. I just had a different opinion and responded. No, I have not compared all the speakers in question side by side but have been all over the country for many decades listening to thousands of different speaker systems and I do have a pretty good ear....Enjoy those Infinity's!
