2 Channel system sounds weak and lackluster

@mark200mph +1   The ear wax + smutz thing is a substantial possibility. It was for me. 

Knowing I have condition called surfers ear I thought I could get ahead of the issue using over the counter applications and rubber bulb warm water rinses during showering. 

When I finally went to the Doctor his typical measure for removing this type of obstruction didn't work as it had adhered itself to the ear drum. 

He filled the canal with a warm solution that works like WD-40 (his analogy) for twenty minutes . Afterwards he was able to remove a 3/8" wad of junk.  

Even a film of wax and dust on the ear drum will could inhibit the quality of hearing. 

Just trying to make audiophile aware of maximing hearing quality and quality of life.happy listering.

@boxboy83 I'm surprised no one has mentioned AC,  quality of AC can vary widely, the fact you liked system in another room points to this. Also none of what you're complaining about point to the room being the culprit, that room is live, full of reflections, if anything you should be complaining about shrill, overly alive sound. Try to audition a power conditioner before making any other moves.

Have your ears checked first after Q-tipping; hydrogen peroxide flushing is a cheap homebrew means as a second follow-up.  Age effects the ears of all, despite claims to the perfection of one’s hearing.

Putter about with some room treatments....usually ignored, but can yield some great improvements without resorting to finding your closest rabbit hole to dive into.

If you plan to reno the room anyway, get that behind you prior to any major treatments.  Any treatments prior to run the risk of being ill-advised or just plain wrong and a waste of $’s and time...

Get a sub sized for the space and note if there’s still issues.

If you like what you’ve already have, it’s a good exercise to improve upon what’s at hand before taking the dive into one’s chosen ’upgrade’ options.....

At that junction, the only sound that sucks will come from the $’s passing through your wallet or cards..... ;)

@boxboy83 A few more thoughts FWIW:  I don't know what Focal recommends for positioning those speakers.  However, I think positioning them (system too? - same cable lengths?) at the long wall was definitely a good decision in a room with those dimensions.  I'm not familiar with your amp but I am familiar with your TT & cart (on my short list when I bought my new TT).  I sincerely doubt the weak link you're looking for is system or component related, especially since you thought everything sounded good at your previous abode.  Rega is a proponent of low mass design.  As such, more than most other TTs in that class/price point, they need rock solid support.  Hopefully, your rack or whatever you have your components on provides that support.  Is the fidelity shortfall across the board or just related to vinyl?  If vinyl only, then I would ask myself how much mileage does the Exact cart have on it?  Are your records clean?  Do you use stylus cleaner?  Have you checked TT calibration settings since your last move?  A well-maintained Exact cart in a well-maintained system using clean vinyl should provide at least 500 hours of solid play.

What kind of AudioQuest speaker cables and other interconnects are you using?  Any chance any of them got squashed or seriously compressed when you were moving?  If so, you might want to check continuity.  Last thought, what kind of connectors are you using with the speakers?  Banana plugs?  Spades?  Might want to check those, as well.

Good Luck!
