Where to insert tubes while running a Luxman SS integrated

@mapman perhaps not, but I’m very satisfied with the combo when I play my good vinyl pressings and even some well-recorded digital.  It’s really bad pressings and some digital that become too harsh (which the R3s do not mask at all—I had the same issue, perhaps slightly worse, when I was running them with the Cambridge). The dilemma is if those particular recordings/pressings can be masked/improved by adding something else to chain.  Or maybe I just need to move to warmer speakers. 

I run a Cambridge Evo 150 with KEF Ls 50 metas +sub and that is a very good combo.  I’ve heard R3s and would expect the same.  The Evo uses Hypex Class D amplification which is very highly regarded. The sound is incite fun and dynamic but never harsh even on recordings that can be on some high end gear.   The Evo does it all pretty much very well for about $3K.  Just add speakers and maybe phono source if needed. 

I bought my Evo from Crutchfield.  They have a good return policy so easy to try with little risk.   I returned the initial unit which had an issue with Bluetooth connections but they replaced it and it’s been golden since.  I always look forward to my next listening session which is always the acid test.  That was January 2022.  

i do agree that if the intent is change speakers from kef to tannoy then i would hold off on any upstream changes until the new speakers are in house, then evaluate all upstream gear to make the speakers work properly in the listening room

Thing is I would not describe KEF as warm. Tannoy tends to have that adjective used to describe the sound more.  If that’s what you want then good advice atty with the speakers and go from there.
