Congrats. Nice system. I'm not sure how much of an improvement you'll hear, you're already using an excellent amp/pre amp. Pass amps are quality. Is the LIO a class A amp? If I recall correctly, I think Vinnie has a pretty good return policy so if you buy it and you don't like it, you can return it. Unfortunately, I never heard one in real life so can't really comment. Btw, maybe another consideration is to move up to 40.2 or upgrade your DAC. Both would make an impact to your sound.
