I for one have never gone to one of the big audio shows, probably for the same reason as the poster, I’m sure mt system would be woefully inadequate after hearing the megabuck systems put together by experts.
@k600r I look at it quite differently. Years ago I was at a show and heard a Wilson Audio setup with pricey BAT electronics that sounded really excellent with one of David Wilson’s chosen demo songs (and I wasn’t even a big fan of Wilson speakers back then). Using that as a sonic benchmark I immediately bought a copy of the same CD to see if my system retained what I heard at that show, and very thankfully it did to a surprising degree. BUT, if it didn’t I wanted to know that and would’ve immediately started to explore what I needed to address to get closer to that benchmark rather than just settling for what I had. To be clear, my entire system at the time only cost one third the price of just the Wilson speakers alone I heard that day so the potential solution wouldn’t have required throwing big $$$ at the issue but rather making better individual equipment choices. My point is that hearing megabuck systems doesn’t need to be self defeating and can be highly instructive in improving your own system within any budget level, it may well just require making some different/better equipment choices.
And while I totally agree that room treatment is very important to getting the best out of any system, in this case I don’t think it’s the fix the OP is looking for. In the above example the demo system’s room was carefully treated and mine was untreated and I was still able to hear that my system was in well within the ballpark of what I heard with the Wilson system. Despite whatever room/setup limitations may exist in the OP’s system, the vast difference he’s hearing needs to be addressed largely through different equipment choices to get more what he’s looking for. Not that treating the room or some repositioning can’t help significantly, but it won’t get him to the promised land in this situation IMO because the differences are just too fundamental and severe. Even without room treatments and optimal positioning the OP still should be hearing many, if not most, of the positive aspects of the show demo systems if his system was more geared to what he now knows he’s shooting for. And again, and to avoid potential flames being thrown, I’m not downplaying at all the importance of dealing with room/placement issues, but I highly doubt it’s the solution in this case. Just my take on it.
