Congrats on your Pass X250.8. I’ve not heard the XP 10 pre but I’m sure it’s very good. I use an older X250 and love it with my ModWright LS 36.5. If you’re not using good balanced cables I would recommend that and don’t use the stock power cords regardless what the Pass manuals state; my X250 manual stated aftermark power cords don’t make a difference but they do. Hopefully your X250.8 and other components have dedicated circuits or you’re not hearing their best; made a huge improvement with my X250. If you can’t run a dedicated circuit then at least pick up some decent receptacles if you’re only using $2 spec grade which is what most homes have.
