High End System Building. How important is the matching, cabling and room? Thoughts ?

my listening room isn’t optimal so I have done a lot of work with everything else to get a great sound that I like. I can’t do much about my room.

@calvinj i figured you were saying something like that.  Fortunately, I’ve been able to get my room sorted for the most part.  Those who can’t have to use different methods to try to achieve reasonable sound.

@deep_333 i don’t know what you read but that’s not how I interpreted his last post.  Room matters a lot, if you can’t fix the room you have to work with what you have.  Getting components that play well together would probably sound better in a suboptimal room than components that don’t.  If you have a room with a lot of hard surfaces buying components that are on the warm side might be better than something neutral or revealing.

@mihorn I agree the room matters a great deal and I don't mean for this discussion to devolve into whether or not it does, just that some folks can't do a lot about fixing it.  The OP is one of those who cannot.  

@calvinj My room is not optimal either, it is on the small side, maybe 12x9, but I've been able to apply treatments that have helped tremendously.  I plan on doing more in the near future but it's pretty good at the moment and measures reasonably well.  I recently added two subs that seem to have lessened the bass nodes I was getting in the room.

I don’t think anyone here has stated that anything matters more than the room.  What do you do when you can’t do anything about the room or very little or there are things you can do nothing about?  Getting another room is likely not a solution for most and a great system in a garbage room does not make it a garbage system.  Suggesting headphones is not helpful either, although it might be well intended. What do folks do when they can’t address the room correctly?  That was the question I thought was being asked here.

The "dealer" would rarely tell you that...he may be all about "matching" expensive crap with other expensive crap and constantly capitalizing on the poor dude’s constant disgruntlement.

@deep_333 i have a hard time believing this.  I’m sure there are unscrupulous dealers out there but anyone reputable who is trying to build a business should be considering the clients room and anything else the client is looking for.  Happy clients mean repeat business and all.  I’ve worked for an unscrupulous boss before and it made it hard to make sales (was in the arborist trade for a while).  Maybe I’m projecting how I would approach sales, although, I hope most dealers have more probity.

Most dealers are like audiophiles here with 40 amplifiers behind them and 50 dac and as much speakers experience , they know the gear , but they dont know much about the importance of acoustics ( i dont spoke about a few panels here ) and about electrical noise floor controls or mechanical vibration/resonance problems

@mahgister that's interesting to hear.  I've loved music for as long as I can remember but haven't built a decent system, at least decent for me 😀, until the last few years.  There is so much I have learned in that time, however, it baffles me that dealers would not be keenly aware of room acoustics, etc.

@grannyring I believe it's easy enough to over treat a room as much as under treat one for sure.
