Just did the same, replaced Krell KST-100 and Electrocompaniet 4.6 with the Pathos classic one. I use Sonus Faber Amator 2, blue heaven for speakers, red dawn for Alchemist nexus cdp.
Something was lost in the bass without the Krell but everything else is so good. I did a home audition and compared the 2 setups and did not blink. The Pathos stayed and it's so beautiful! At the low(ish) levels I hear it's so much better. I will change cdp next and maybe speaker cables.
Minotauro-Did you try the Red Dawn for speaker?
