I had an interesting experience today when I accompanied a friend to a high end audio/video store. My friend was interested in auditioning some very high end speakers for two channel listening. Much to our surprise the sales associate was running all the music off an iPad which understandably is probably the most efficient/practical method for quick music selection. One important point the salesman missed was the fact my friend does not stream music and only plays vinyl. There were some very nice turntables in the store however not setup for auditioning. A missed sales opportunity I suppose?
