I thought this would be a great place to share (vent?) my current experience. I have a small Youtube Channel focused mainly on testing Vintage (say >20yrs old) audio gear (namely amps, preamps, & receivers)and seeing how well it performs to its original specs, as well as how it sounds to me (basic sounds, shoot me if I use the word velvety). Similar to what Amir (and others on this site) may do, but I have nowhere near his knowledge, experience or equipment. I'm a retired EE and this is what I have found to do to keep me off the streets at night. I recently posted a video "$8000/pair Speaker Cable vs. $14 DIY Speaker Cable A/B Test"- you can search for that on Youtube if you are interested. I probably get 200-300views in a week on my videos. THis one got about >4000 the 1st week. I am the 1st to admit it was not a perfect test, but it was the best I could do with what I had. It was basically a get together of about a dozen of us "audio guys" to eat, drink and talk audio, and participate in a test. I reply back to every comment in some fashion, but boy, did I get a bunch of people chiming in about how you can't use just one speaker because you can't just imaging and the system was not good enough to hear the difference...blah blah blah... Last time I checked I was at 95% likes so the majority of folks get it. A few of my favorite comments were that I did not send the cables back to the Manufactured to be "tuned" for my speaker and amp. I tried to end one commentary with just saying that we will just have to agree to disagree, just please don't tell me that you can hear a difference when you switched out your Toslink cable. Of course he did, and he went into all the reasons why...temperature, magnetism, no reflections around the edges.... I just shake my head and chuckle..... Am glad I can "vent" a little hear.
