I have run Running several systems at shows , for one many displays incredibly don’t even fully runin their systems before hand, which makes No sence,
also bringing room panels for reflections- absorption, and many people feel that have to blast it at 95-100 dB to make their point and in fact because of all the other factors actually sounds far worse.
MBL for Example ,these Great 101 speakers with all reference gear in a room not big enough, can sound congested, in a proper Large room Magical. Many rooms many either don’t know ,or willing to take the time to setup properly.take the Cardas setup method for example you can see on their website
pretty reliable in most cases. Erik is correct most respectable audio systems
at home sound more coherent and musical ,for you took whatever time necessary to Taylor your system to your room . Maybe a few exhibitors will
heed the comments and advise.
