Copper, mud, potato, banana. Can you tell the difference?

An interesting experiment taking place in this thread over at diyAudio.

I'll give it a listen if I find some time.

Hopefully he'll get some FLACs up in a shared Dropbox folder.

Oh, this opens up a whole new world.  


"So, what's your favorite cable recipe?" "I'm partial to the boiled Yukon Gold, sautéed with garlic and cloves with a dash of Moroccan Tagine sauce.  For my connectors, I prefer a copper base simmered for 30 minutes the drizzled with 24K gold, at topped with an insulating layer of avocado peel around the handle."  



"I keep my interconnects refrigerated at 38 degrees.  You?"


"I had a huge weekend party, left my system on for 48 hours straight, my cables spoiled, now I have to (buy, bake, brew) new ones."  


And for the Best Buy crowd, "They're having a special on Frozen TV HDMI cables this week!  You can get a six footer for only $99!" 


Or, "I fried my cables this weekend." 

"Really?  What oil did you use?" 


Help me...I can't stop!


"Kimber now offers high flex chewing gum-based interconnects.  Get them with the optional caffeine kicker.  They won't sound better, but you'll get more listening done in less time." (I wonder if that's too obtuse, or will somebody get it?)

Me too! That has been long established as the optimum temperature for interconnects. Too hot, and some of the sound signals might get too excited or some temperamental ones might result to violence and damage your cables from inside out. Too cold, and they tend to end up rather lethargic and might choose not to travel through the cables at all!


At 38 degrees, all the sound signals are at their best behavior, which translates into better bass, smoother mids, and perfect highs. The veil that is usually present is non- existent all together.

I use only the highest quality mud and only the absolute freshest of bananas for my audio needs. biggrin.gif


So you say you use ordinary, out of the backyard mud? Pfft. Plebians.

Did you find some kind of legit tell or some kind of cheese / cheating?


I tried A vs. B with the FLACs and ended up with 30/30.  Let's just say that I found something dumb or trivial to compare that was an easy tell, and that I didn't spend much time on that 30/30.  D also has a glitch in it and is missing audio for part of it.


As for what legitimately sounds different, I haven't really found anything I can report for real.  Maybe if I give it another listen instead of just skimming it to search for artifacts and quick tells...

No I wasn't looking for glitches or problems at the start of the track or different time alignment or such things but differences in sounds (instruments, voice) ... and found a distinct difference that is audible throughout the entire track.
