Is my Salesman telling the Truth?

As for your salesman's comment about network cables, it's bunk, too. Whatever effect those networks have, they'll have on any signal passing through them.

I have had the same experience as Adamanteus, where a salesman will disparage a brand he doesn't carry. I hate this. In fact, when I go to a new shop I will sometimes bring up another, competing brand to gauge the reaction. If a salesman starts pooping on a brand I know well and have had great results with, it ruins any credibility he might build with me. At that point, I figure the guy is just "moving metal," couldn't care less if I get the best component for me, or if I ever come back to his shop; he just wants to sell me today what's best for him. Such behavior is pathetic, especially in a field where buyers can become loyal and will come back many times over many years.

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
