Is my Salesman telling the Truth?

Your salesman is telling the truth alright - as long as it works for him. I was in sales years ago and management DOES put pressure on to push products that have a better profit margin. Not only in audio but everyplace. This is life and that's a fact. That does NOT mean there are no honest salespeople, it only means that most honest salespeople who work on commission don't take home big fat paychecks every week.
What you want to do (and it takes time) is find a dealer you like and you can deal with for MOST of your gear. It takes time to develop a relationship...lots of time.

Your salesperson may be relating his own experiences truthfully so I can't argue there. That said: I must emphasise that my own experiences with "networked design cables on single wire post speakers" has been very satisfactory.

3chihuahuas: if you believed "your sales guy" was spoutin' bull dung, why didn't you tell him? i find it fascinating that so few consumers - of damn near anything - are unwilling to confront uppity salespersons, even politely and diplomatically. my view is that silence in the face of bullshit begets more and smellier bullshit. unless you're in the fertilizer biz, speak up or stay away. otherwise, you're gonna' wonder one of these days why everyone's avoiding you while simultaneously holding tight their nostrils. just my opinion, FWIW. -kelly

Kelly, sometimes I have to "hold my tongue" and walk away in many cases because if I get started I may not have the control to hold back if things get heated and the bullshit is flying out of some fool's mouth. I am very passionate about the truth, and have a bad temper that I am not proud of. (My silver hair used to be red.) Salesmen who call on me in my vet practice are very, very careful. I have been known to excort them to the front door and somehow that word spreads. [:)] I wish I had thicker skin, really. Charlie
