    I'll do you all one better. What if I go buy some pure 6 AWG copper wire (used for electric ranges), shield it with aluminum foil, and then see if I can hear the difference over that vs 18 AWG RCA CCA speaker wire?

    There isn't an 'audiophile grade speaker cable' in the world that could match it in terms of conductivity, power transfer, and low resistance
    I'd like to buy some popcorn and watch, as you try to connect 6 AWG wire to speaker terminals and an amp.

    Chris, I appreciate your enthusiasm, and there is always the need to inject some youth into this hobby. But, I recommend that you slow your roll, and glean some knowledge from the old farts here. If you behave, you might even find yourself the recipient of some freebie equipment for your own personal experimentation.

    I preferred the sound of these inexpensive ($320/8ft pair) silver coated copper braided speaker wires in my system vs regular copper.

    Which ones, Drew? I wasn't able to remotely activate your webcam at the time of your posting to see which ones you were talking about. I was able to later though. Side note: your cat's litter box needs attention, and those new sofa cushions are awful!

    Talked about them here: https://forum.polkaudio.com/discussion/195541/five-way-speaker-cable-comparison

    They aren't available anymore it looks like, but these are pretty similar: https://www.ebay.com/itm/255294394140

    They have gold plated spades/banana plugs vs the "rhodium" plated ones on my set, but the actual wiring looks to be exactly the same.

    Edit: Looks like it, or something like it, is available in bulk as well: https://www.ebay.com/itm/325726890719

    Ah, nice. I remember that shootout you detailed. Great example of the kinds of differences one can experience with different cable designs in a resolving system. Thanks for the new links, as well.

    I've been curious about rhodium connectors from back when I was trying to choose connectors for my DIY builds.

    FWIW Rhodium doesn't make the top ten in conductivity, it is a very hard metal and many times it is used on items that get hard use with many plug-unplug connections. They also like to flash it over silver to keep the wear off the silver. Either way it DOES have a sound signature, I think that is where many people say silver is bright and brittle sounding, which I agree too much silver in ones system can be harsh/bright, but I think what many attribute to the silver may be the Rhodium over the silver.

    Hmm, so I've come to an epiphany.

    If cables (conductors) don't affect sound, then how on earth do capacitors affect sound (which I've personally heard the massive differences they do make)?

    They're both just conductors, yet ClarityCap PX, CSA, PUR all have a different sound to them. Perhaps some testing is in order. I wonder if some local audiophiles would have some gear I can use to measure sound signatures with. Would be a very cool experiment.

    Because ears aren't reliable due to the brain. The brain is a very cool meat computer but it can get pretty messed up. Was it Monster who made people think their cables were better simply by turning the volume up a few decibels?

    Either way, the ears alone are reliable, but the brain isn't, and it can be subtly subconsciously tricked too easily for me to consider my subjective testing good enough to be fact.

    You’re contradicting yourself, aren’t you? How can you be sure you heard differences in the various caps, then?

    Good point. I suppose the only real argument I could give is that with cables I'm testing frequency response, the capacitors actually gave entirely new detail and let me hear parts of the song I genuinely couldn't before (I did do a comparison side by side with the old board).

    I can't necessarily say I genuinely did though, it really could be placebo. I do know that the parts needed replacing anyways because they were like 35 years old and would be drifting out of tolerance anyways. So even if it were placebo I can still justify the new high quality components.

    Yeah it's entirely contradictory, I've acknowledged that. I'm just saying that I'm open to the fact that it's placebo. I mean, hey, wouldn't it be funny if I was wrong?

    I hear a difference, yet it might be my brain playing tricks on me. Seems to make sense to me. My perception might be different than the objective truth. So what? I could have worded it better but you know what I meant.

    No, I massively, entirely, genuinely don’t know what you meant.

    You either heard with your own two ears (and, yes, brain) differences you described with those adjectives/adverbs, or it was placebo.

    Which one?

    Having a little trouble are we? I believe I heard with my ears, but it also could have been placebo.

    If you need an analogy Id be happy to provide one

    Just buy a cheap system and tell yourself it sounds better than anything you've ever heard.

    So on that note, I was looking for identical albums on HDtracks that I could get in different SRs. I got distracted when looking for music that I'm Familiar with and found this: https://www.hdtracks.com/#/album/5debab08f73cc8ae84d3332e . I'm a huge fan of Radiohead and lately cover tunes. It comes in two different SRs and bit depths.

    Interesting. I like a couple of those Radiohead tracks. A bit pleasantly-melancholy/haunting. Is that that singer's vocal style?

    When you buy music on HDTracks, if you buy higher resolution, do you also have access to lower resolution, or are those separate purchases?

    You know your question has got me thinking. Couldn't I Take an album in 192Khz and down sample it step by step? I'm thinking I could save some $$ by not having to buy the same album over and over, just make the devices do all the work?

    My experience With downloaded hi-res is that it's only in the SR/BD that is downloaded in.

    Yeah, you can. I wonder what they use to create lower resolution versions, and whether it matters. I'm sure somewhere there's an argument about this on both sides.

    I'm not familiar enough with this process. Are there music processing engines that are better than others?

    Would you be able to tell the difference if you just downsampled in Audacity or CoolEditPro? (is that even around anymore?)

    I suppose you could convert a track and then compare the waveform to a downloaded one for a visual sense as well as what you hear? Not sure any of those tools would be definitive.

    Reminds me of a discussion about cables some time ago. I came across a vendor or manufacturer a while back who proposed using a "difference" wave or file or something. I forget what it was called, but it involved taking a recording of playback output from a particular set of parameters, and overlaying that recording on another one, capturing the diffence data to a new track. In theory, this would give you an audio recording of what is different between a control and test track.

    I did this, and it actually, works, however there's a glaring question of timing, and how sensitive the ear is to offset.

    See, the tracks have to be overlaid at the exact same point of start. Audacity, I think, was only accurate to hundredths or thousandths of a second, so while there was difference data between recordings from two tracks, I couldn't be sure whether it was "missing" information, or simply delay offset data, or maybe both.

    It was interesting, though. I'll try to find that thread.

    According to a study conducted by Aalto University and genelac, the human ear can detect timing anomalies to a half a millisecond.
