Well gents, I have a Krell FPB350MCX monos and not optimised to bring out the best of them with my system..the Krells are close to bright,,,a bit edgy, dependant on CD..I'm looking to get the 436 to run the top end and my Krells to run the bass..Speaker upgrade after my 436 purchase.. Nola vipers to replace my B&W 801'sD.
