Pass Labs x250.5 vs Sonic Frontiers Power 2 SE

Hi, I am thinking about changing out my Sonic Frontiers Power 2 SE for a Pass Labs x250.5 and was wondering if people think that change would be a lateral, forward or a backwards move. I do not have the opportunity to demo the amp at home on my Tyler Acoustics System twos. I've had the SF for almost 5 years now and am itching for a change. The amp has been the mainstay over many other changes but I think it is time to try a solid state amp again. The rest of my system can be seen in the system link.
