It gets better each day if it possibly can Tony. The increase on the bass is one of the bigger changes I've noticed. I no longer use my 18'' sub if that's an indication. My polks actually sound better without it where that was not the case with the 33. The improved clarity also still amazes me and I finally know what my Polk 1.2tl's are capable of. The 3d soundstage and placement of instruments are almost spooky at times.
But that also comes at a price as there's also been some problems lol. I can now hear differences in cabling which I never could before. I was perfectly happy for years with what I thought was decent cabling (cardas and mogami) but now I'm buying Kimber and MIT. I'm also wondering how modern Mac amps with better specs and balanced inputs sound now
Yes the honeymoon is still going strong and this C100 is quite possibly the best upgrade I've ever made and no doubt it's a lifetime keeper. Not to mention using the C33 on a much lesser secondary rig has also been a significant upgrade over the C28 and MX113 I was using in rotation.
