How good can it get, really? - my stereo sounds amazing!


I really love my stereo currently. I keep thinking I should be looking for the next piece to upgrade - phono stage, stereo subs, etc., but honestly not sure what to change or why I’d potentially spend more money to achieve a result that’s lesser or equal to my current sound quality. I sorta feel clueless as to how to proceed without screwing up what I have. I know it can get better but honestly I’m at a place when I just don’t know how it can. Hmmmmm.... not a bad problem I guess. Open to suggestions for sure. Thx.

A little note of encouragement from a reviewer of 13 years:

Stop being such a chicken! Scaredy cat! MMnnnnn - phooey! ;)

There are many more levels of sound quality improvement than you can imagine. You are not close to the ultimate.

For instance, as a thought experiment, imagine spending time in your home with some of the major genres of speakers - panel (magnetic planar or ESL, horn or horn hybrid, line array, etc. Just considering the different genres of speakers and the potential for improvement, you are far away from the potential that systems have that may sound far better to you, literally dozens of levels of sound quality. Frankly, there are more levels of sound quality available than audiophiles will experience. That is true for nearly all audiophiles, myself included. The odds are very good that you are nowhere close to your dream sound. Just because it sounds terrific to you in no way means it cannot get much, much better.

For instance, if you were to switch to a floor standing speaker, there would be many potential improvements associated with that move alone.

Keep a notebook of your current favorite system from first power cord to speakers. Make changes, and if you don’t like them, revert.

BTW, if your first priority is to not spend money, then pay a lot of attention to burn in, and tweaks. That will keep you right in the same performance zone, but you will have saved your money!  :) 
There is nothing - repeat - NOTHING wrong with your power cords! To believe otherwise is to be caught in a neurotic obsessio! Ditto for your interconnects! 
Wire has become a lucrative market for the unscrupulous to prey upon the gullible. Tweaks and burn-in? LOL!
You guys, I am absolutely enjoying my stereo - as stated above, I love it! I’ve been living with it as-is for about a year now and still love it. I listen to it every day. 
I recognize that just going to floor standing from stand mounts would change things (likely for the better) but maybe not? I’ve read that the 804d3 is actually less detailed because of the two in cabinet woofers vs. the 805d3. I wonder if trying a second Rel sub is a better route? I agree - I just need to experiment a bit. Or maybe I go back to an all tube phono stage? So many options for sure.
