Which power amp is a good match for CJ 17LS Preamp

Is any audiophile who owns a CJ 17LS Vacuum Tube Preamp? And which amp should be a best match for this awsome preamp? I tried to audition McIntosh MC2102 Tubes amp and a Sim Audio W5 solid states. But when I listened to those matches I did not hear any differences between them. The interconnects are Kimber Select 1030 and Silver Audio 32 speaker cables connected to Cabasse Iroise 500. Is anyone suggesting any changes?
