Pass X1 / X250 - how to get a bit foregivable ???

Hi, my system is

Pass X1/X250
Lindemann D680 SACD/CD
Jean-Marie Reynaud Offrande speakers
HMS Sestetto balanced signal-cables
HMS AC-cables
HMS Fortissimo Bi-Wire speaker-cables

Who has experienced "successful" system-
cabling to reduce the brutal honesty of Pass X1/X250
(or similar) amps in combination with highly resolving
speakers and high esolution source ?

Bad recordings are sometimes just very hard to take
and stress my ears. Also the overall sound of my system
tends just a little bit too lean and organic weight is
missing.

I did not try out different cabling yet, so any experiences are appreciated.

I tried out replacing (a) X1 by E.A.R. 864 tube pre,
(b) X250 by Manley Labs Snapper or (c) both, but the
lack in soundstage and resolution compared to the Pass
amps was so much degrading (sorry) the purity of the
original recording by adding content that was just not
part of the recording, that this was no acceptable
solution either, at least IMO.

Please, any hints/ideas are very appreciated.

Regards
