Best integrated for PSB Imagine T2's

I would probably first replace the phono stage, solid state or tube - it depends on your taste and compatibility with your future integrated amp. As for the integrated or the idea to replace the speakers first - both are valid approaches, I think. I'll just mention a few amps without knowing your taste or how exactly they would work with your speakers: Pass INT-60 used, Regdum RGi120 new directly from Australia, Manley Stingray new or used, Pass INT-150 used, Rogue Pharaoh new, Octave SE edition used.

easola01 oops, my bad I thought the Django's were $6K and the Vandersteen Quatro's are now Quatro CT at $14K. Vandersteen Treo's are $8K. I was also discounting the $6K DAC. 

To be clear I consider well designed speakers the most important component. I went round and round prioritizing bandwidth in economical speakers. The very minute my out of position Avaoln's played with my crap electronics my trajectory with this hobby was significantly altered. Even my more than crap electronics waiting to be sold became acceptably impressive. 

Of second importance is my phono cartridge. If you value bass get two sealed DSP subs and not inside the speakers. 

If your thinking of the Bryston you have to consider that it has a 20 year warranty and from what I've heard of the new cubed line sounds very nice.  

The project xtension10 has a sumiko blackbird cartridge. The musical surroundings is a design by phono preamp designer Michael Yee....so I think I am good there. Upgrading speakers is a thought....a little tepid about buying speakers used though...but electronics I am more comfortable with. Good suggestions...need to do research!
