OP,
Thank you for your kind words.
I can’t tell you how much better my system sounds with the careful tweaking I have done (something a system at any level can benefit from). The room tweaks… getting the equipment racks from in between the speakers. Deadening the wall behind, speaker placement… etc. have improved the sound quality.
You noticed the room… well that was luck. The best room I have ever heard. My audio guy as well… and he has been installing $100K+ systems for over 20 years… many in dedicated, purpose built rooms. As I said luck there.
BTW, in a previous house, with ribbon speakers using a 1’ wide by 4’ strip of thick wool carpeting made a huge difference in imaging. While a much more modest system, I would have put it up against much more expensive systems. It is not all about cost… tremendous advantage can be gained by effort.
But, your system can be every bit as rewarding to you. I have had many systems, and listened to dozens “better than mine”. They helped me shape the direction I took in constructing mine. Listening to great systems is a great way to learn. Surprisingly, often jealousy does not ensue.
My dogs enjoy music and are why my audio seat is a love seat… one place for me, and one for the dogs. I also love it when they take up an attractive pose in front of the system.
