How long to burn in Graham Slee Amp 2


I decided to try a SS phono stage the Graham Slee Amp 2 SE. I have a standard VPI Scout with Dynevector 20X H.O. cartridge. I used an ultra modded ARC SP6B it was truly a noisy pre (I uaed the best tubes around) in addition it lives up to reputation of being a pre with gain gone wild I could not control.
I hoped the AMP 2 would have a very low noise floor.Indeed It is very quiet.It doesn't have a big tone sound I like either.
I am not a big vinyl spinner but usually start my listening sessions with at least one record. light use maybe 6-7 hour/week. I have had it for 6 months a least. It is left on continuously.
However I get persistent glare and a grating, smeared treble.It sounds just like a typical cable or component that hasn't broken in yet. Could that be the case here, how long should it take to burn in? Is there another problem entirely?
Thanks for your thoughts.

The cartridge is in my original post. I run the Graham Slee into an AE-3 pre that is incredibly good then Cyber 800 monos to JM lab 936 Electras .
