APL 3910 owners, has anyone tried APL upsampler?


I placed order today for APL 3910 and Alex offered me to install his new upsampler board too. I choose to go with it but I've asked him to have it installed as switchable option.

I wonder if anyone of you heard his upsampler?

I see that a company called Hot Rod Audio Mods is offering an APL clock package for the 3910. Can any of you speak to what relation Hot Rod has to APL? They say that just replacing the 3910's clock with the APL clock is the biggest improvement that can be made to the 3910. Can anyone speak to this. Thanks,
