Kenwood KA-8100 integrated Amp

I just acquired this Kenwood . I am impressed with how good it sounds.!!
My current system is as follows:
 Speakers are Zu Omen MkII with 16 ohm drivers.
 Amps are Wyred 4 sound Class D SX1000
 Pre Amp is Audio Research LS7
I am tempted to keep the Kenwood over my current Wyred4 sound and ARS LS7
 How would you compare this Kenwood to my current components ?

Thank you
