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

Go with the Rogue. The Nakamichi is a 30 year old amp and they been out of the Audio business for years. Rogue is only a phone call away if you ever need service!
I got the Rogue  Great anp but does not seem to be a good match. Very dark with a rolled off top end.  Tubes big surprise.  Switched back to the Yamaha  M4 and CX 800U and it was like a blanket had been taken off the speakers.  Larger stage more dynamic  yes brighter but way more alive. I kno0w I can change out tubes but not looking to go down that never ending road  The age of a unit does not matter to me.  I find most older gear sounds more musical and with more body verses much of the hyper detailed thin sounding outright weird newer affordable gear.  i hear this from others all the time.
If you're having that kind of trouble with the Rogue, maybe you should consider a different pair of speakers.
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......
