JR concentra II vs. BAT + AR VT100II

I have one pair of sonus faber guarniere, I use one BAT VK 5i + Audio Research VT00 mkII, I like the sound , but I have some troubles with tubes changing , because I live in a very distant Brazilian city, so I am thinking in change again to SS( maybe all equipments) and to simplify I think in change to integrate- I would like to know about the JR concetra II, or better to wait for the new JR concerto? Is there big diference with my equipement( I do not import about lessing in warmth)?
