Is upgrading pre worth it?


I Own a Denon 7.2 receiver. I am using it for a pre.  I have an st100 Rogue amp. What difference would  a nice pre make?  for 1500 used Rogue pre would I get 1.5k worth of sound.

Congrats and happy listening and please do let us know how it all sounds!
FWIW, I recently replaced my longtime solid state McIntosh preamplifier with a tube unit. For me, the change was epic. Please don't attack this statement as it is no reflection on McIntosh. I think everyone has an ideal image of what sound they want, and for me, the tube preamp makes it.
I tend to recognize more of a difference in preamps than amps in my setups. More detail specifically, maybe ’air’ as some define it.

I’m not doubting other’s opinions at all. But I know when I ended up with my first nice preamp, (nice to me) it changed my expectations regarding what was possible.

Much more refined and expensive gear than mine on here. In my case it was a preamp that retailed for around $2,500, but I really enjoy it.
