@chasda take advantage of the opportunity to demo and listen to as many different manufacturers as possible.
My journey in audio has taken multiple steps and a Yamaha receiver was a significant step up during my journey.
What I've learned in my journey is manufacturers and amps sound different. If you like them they sound good if you don't then they don't - but the reality is every manufacturer is forced to make compromises and the end result is a specific characteristic.
I have owned McIntosh and thorough enjoyed my units with a tube pre and SS amp. When I decided to upgrade I was able to listen to Audio Research, Rogue, Moon, Boulder and McIntosh. I noticed my tastes changed and ended up switching for McIntosh. Enjoy the process and what every you decided - the person to satisfy is the one looking back at you in the mirror!
