maybe not demonstrating gear at it's best also helps explain the disappearance of audio stores...I have never been in sales, but it seems an odd way to sell product...I would think the store would want their gear to sound great or else the customer won't buy it, and also sell power and room acoustic gear too...Are you in audio sales maplegrove?...I would be curious if that is common practice, as we have many dealers on these forums...
