Preamp Recommendation


Hi 
I have just purchased Classe CTM-600 Mono blocks. They are currently running with an old ML 38s. I have tried using a VTL 6.5 III but had a hum problem. Tried everything but could not get rid of the hum. The 6.5 was not new so the pre it self could have had problems. 
I have an option to buy an Ayre KX-R at a great price. Question is will the Ayre a significant upgrade on the ML? Speakers are B&W 800 D. Sources include Clear Audio TT and a PS Audio Directstream Junior. 
Thanks

I think there's a certain darkness and quiet of the Ayre designs which would work very well with B&W speakers, but should listen. :)
I like the 👀 of that gamut! As far as preamps passive is really good but I like a little gain and tube dynamics. Doesn’t anyone use tube amps? Just kidding!😊
The Ayre will be a rare experience.
Due to the Teflon boards, it needs run in playing music for 4 to 7 days
once it's done it will be obvious how special it is.
Best,
