Amps or Speakers which one to upgrade next

Me too Jond!  

Looking at your setup. It’s very similar to my original setup, except I had my CM2 driving a pair of Harbeths. Let me ask you this...when you say “better”,  what are you looking to improve?  Do you feel it missing bass, details, clarity, soundstage? I think if you provide the forum with more details and insight, we will be able give you more and maybe better suggestions.  Also, I would also go back to JohnnyR and get his take.  He understands great sound. He helped me build my new system and I’m very happy.  

While Rogue may be a "value brand", as I and many other contented owners have discovered, it offers not only bang for the buck but also very good sound in absolute terms.  My CMII is driving PMC twenty.24's.  My point is that if you were to buy $7K speakers, and even more so some gently used ones at that price, the CMII would still be no slouch at driving them.  That's the conundrum.  Does an Audio Research tube integrated driving 2ce's sound better than a CMII driving Treo CT's?

I looking for better transparency better bass control and little more power  I have listen to Van 2 with the AR vsi 60 not a big enough step 
I talk to John all the time and at the store very couple of weeks

so far on the my list Aesthetix MIMAS integrated when released
