I go to shows mainly to hear what is supposed to be the best hifi sound. I always find a couple setups that I determine sound best to me. Yes Fritz and Vandersteen seem to always rank high.
Then I go home to assess what I have versus what I heard. I do a lot of homework and try to make well informed decisions. Experience, reviews, value, specs and measurements all come into play to help make a good buying decision.
Nice thing is I have not felt need to make a change as a result of show sound for several years.
Cost is not the driving factor. I get that sound at home for much less cost than most hi end show systems by doing the homework and learning along the way.
After all, it’s a system and systems must be integrated properly in order to perform best. The room is probably the most important part of the system to get a handle on because that might be tweaked but can’t be changed. That determines your speaker options and you go from there to get the max out of the speakers.
My goal recently has been to retain that sound while downsizing. I do a lot of homework to try and identify the technical innovations that might help and learn a lot along the way. The latest and greatest Class D amp technology has perhaps Been the biggest game changer, followed closely by wise application of DSP for room correction and other sound tweaks as needed.
Just my few cents….
