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

Rich, Thanks for your input.
I want to mention that I don't have a Yamaha...I have a Kenwood KA 8100 with dual power supplies .

I owned a pair of the Wyred 4 sound Class D SX1000 mono-blocks and quite frankly other class A or Class AB amps breathed a lot more life into the music. I have not heard your preamp which others made mention of, but I know the preamp I was using sounded very good, but all music sounded much better with the amp changed out.
Since you like the Kenwood better,  you should sell the other gear and enjoy it! It all boils down to what you like!

Bought my Kenwood KA8100 new in 1978.  Used it for about 5 years of light use, then gave it to my folks to use in a living room system where it sat in an enclosed cabinet for the last 40 years.  I doubt that it has more than 100 hours on it since that time.  Just hooked it up with a pair of tube mono blocks and it actually sounds very nice as a preamp.
