Can’t speak for the .8 series but I own the original x250 and it’s still a fine amp. I was fortunate to bring home a used .5 and yes I could hear the difference but as it goes I could not justify the difference between selling mine and buying the .5, and deep down I’d rather just hold off for a .8. I have not heard the .8 but I’m sure it’s a great amp. Not sure if it’ll be the same but my ModWright LS36.5 preamp works great with my X250.
Might help knowing your current amp is and what you’re looking to achieve. Also what are your speakers?
