Speakerguy, you do know they make optical rotary encoders right? =)

Actually I did, but I seemed to have forgotten when writing that post! I'm only 29 and my brain is going already

And I still like the heavy resistance feel you get with a motorized or one of the nicer conductive plastic pots. But after owning a receiver that had very poor L-R tracking at low volumes, I am very much against the dual ganged pots of any type.

Like I said, the mechanical resistance is trivial, it can be added with something as simple as spring and low wear material in contact with the rotor shaft. That's all that makes a POT drag anyways is the wiper contact. I would never recommend ganged pots in general.

I've always believed that if my scope or distortion analyzer doesn't show it, than I certainly can't honestly hear it -- it's subjective at that point.

Well, most scopes are 8 bit, so that's not great judge of something being audible. But if a good distortion analyzer can't measure it, then it sure as heck isn't going to be audible.

When I was a teenager I remember an old antique "Victorola" with a square cross-section wooden horn in the body of the cabinet, originating from the bottom of the hollow "tone arm". The horn had a little paper sticker on the inside that said "Made of the finest piano and violin sounding board". These marketing schemes have been going on since long before Edison, ergo: "snake oil"

Monster Cable, -'nuff said.

There may be some truth to that since pianos and other string instruments owe their sonic quality to the types of wood used. It's a crucial part of their construction design that sets apart the cheap stuff from the very good. Wood choices used for making guitars is a classic example. A Bosendorfer piano is a very highly acclaimed instrument, owing it's elevated status to its sounding board.

As for Monster Cable, heavy guage speaker wire has a good purpose its the application. The price is another thing, but using quality copper and heavy guage to accomodate hi-power amps is a good thing.

Monster cables are definitly over priced, but I'd buy one if I wanted a decent looking as well as quality audio cable. If I didn't care about looks I'd just hook up some beefy copper

Here is the source of that beautiful material

I'll buy 20 of them!

The links to the audioholics website is quiet nice on that Audiophile site. Lots of good links to REAL information to improve room acoustics and full explanations for the actual mechanics that are going on.

Excellent link to some amazing "snake oil". What a laugh... you made my afternoon. I especially reeled backwards when I saw The Altmann "Tube-o-lator" lacquer and notice in the product's specs. it states 20 days for full curing time (sonic). LMAO.... they prolly figured that your mind will convince itself of sonic improvement over that time period. And people buy this crap?

Sceadwian · 2nd November 2009, 09:52 PM

Check the audioholics site out, I found it towards the bottom of that site, it's got some really good articles on how to REALLY improve audio quality for true audiophiles =)

Some of the reviews of the "Wattgate 381 Audio Grade Duplex Socket" are quite funny and could have been written by some of us.
