Perfect Path "Solutions" (PPS) eMat

"If you do post anything useful, its ability to have any positive impact is neutered by the accompanying condescension."

@audio2design You kill the usefulness of every thread you participate in with claims of superiority and otherwise irrelevant commentary. 

If you do post anything useful, its ability to have any positive impact is neutered by the accompanying condescension.

If your expertise actually matched its claimed size, you'd find a way to communicate the knowledge without all the bullsh*t. It's just ridiculous.

And to get back on topic.  I do not have any PPT mats installed (and haven't heard them), but will happily do so if you buy the house.  

PPT did not make "graphene", they incorporated graphene into a carrier/solvent. They didn’t have a graphene formula, they had a formula for a carrier/binder used in the contact enhancer. They would have bought the graphene. Judicial use under the label .... sure, that is why the mat is pretty flat on the label side?? You would have had better luck claiming it was on the other side, where it was a flat but a bit bubbly on the first one, but flatter but grittier on the "upgrade". There are a ton of proper EMI absorbing mats on the market that use graphite, and ferrous particles depending on operation method. I will give you 3 reasons why they don’t use graphene and cost and too difficult to manufacture are not it.

@audio2design Here, let me give you a demonstration for how to post without the condescension. I suppose you enjoy the fights you cause on every thread, but if you really do want people to listen to you, simply saying the same things without the insults will be a lot more effective.

"As you know, the primary invention of PPT was to create a carrier/solvent formula that allowed graphene to be easily applied to other surfaces. I have my doubts, however, that this is being done on the mats, as one would expect the surface to be a lot more "uneven" if covered in a graphene paste before label application. Even if it is applied to the mats as suggested, I don’t believe this would make them more effective EMI absorbers. There are three reasons why commercial manufacturers of EMI absorbing mats don’t use graphene in this way. 1. xxxx. 2. xxxx. 3. xxxx."

As is your actual points get lost in the noise.

@tomic601 Thanks Jim, I appreciate it.  Everyone suffers intensely in this life and learns to live with it in their own way.  So unfortunate that there's so much pain out there.  At least we've got music.

And thanks to you too @mahgister

Have you been told yet today cal3713?

So many condescending people in this thread but I am your target. You need a life and some perspective and perhaps a lesson in objectivity.

@audio2design

Indeed, I definitely need a life.  After my best friend was murdered I lost my dream job, a 17-year academic career, a 5-year relationship, am bored out of my mind, and just had to pack up my system because I'm being forced to risk my life and move across the country for a job that provides zero enjoyment during the middle of the worst health crisis of the past 100 years. 

Regarding perspective, thankfully I've only lost a 93 year old grandmother to covid and actually have a job and get paid so I'm not suffering acutely like so many out there.  So many people are losing dear family members and are worried about feeding their families every day right now...

If you could just reflect on the number of threads you participate in that devolve into unhelpful bickering like this one, I'd really appreciate it.  Obviously others are also guilty, but you really do attack people a lot and then talk about how dumb they are while citing your superior experience and knowledge.  I'm probably just more sensitive to it from you because I got swept up in such accusations a while back, sorry... 

And sorry for the off-topic post folks.  As I said in the "angry audiophile thread" I just wish we could all try to help each other learn about music reproduction without the personal attacks. Education without condescension.  I'll work on getting better at it myself.

Thanks all.  Much appreciated.  And if you wanted to help out in any other ways, I'd be really happy if you felt like buying my house! 

Walking distance to over 100 bars and restaurants and two of the major indoor music venues in Denver, 1.5 miles from downtown, 1.5 miles from the botanical gardens, and the appraisal went from $440 to $660 in 4 years, so it's a wonderful investment.  That trend isn't stopping anytime soon.

@tvad Thank you.

@oldhvymec Thanks for that story. It’s just impossible to accurately imagine how much suffering people go through in this world. No matter how bad you have it, sadly someone’s always beating you in the competition down the well. It’s a shame it’s so hard to keep those downward comparisons in mind when your personal issues are at the forefront. In the end I guess it's because pain is pain, whether it’s from a 2 year old not getting their way or the truly horrible shit that happens in war. It’s activating the same areas of the brain.

As I said above, hey, at least we’ve got music.

And on-topic. Agreed with the statement above... even if these matts (or anything else in audio) are just placebos, why not? Research clearly demonstrates that placebos can be just as real as the drugs they mimic. Hell, they might even have fewer side aside from the risk of social mocking.

As everyone knows, you can find other places on the internet (and threads here) where people will mock others for claiming that they hear differences in amplifiers, dacs, cables, and power cords. Basically everything besides speakers...

It’s really all about where you draw the line, and whether you’re willing to experiment with things just over that edge. If you go far enough back, you can find some post of mine citing expectation biases and discussing how it’s just impossible for different power cables to change the sound. I mean, they’re before the amp’s power supply!?!? If it’s actually correctly installed, and providing AC without limiting current, how could different cords possible influence the sound??

Well, one day I gave a different cable a shot and damn, it turns out my knowledge of how music reproduction worked wasn’t sufficient to guide me in this domain, because it really did make a difference.

Like @audio2design, I’ve taught about expectation biases. I did so in top research universities and even have an international "paper of the year award" for a theory about how expectation biases work to change judgement, behavior, and motivation.

But while expectation biases nicely explain why "fancy" looking cords sound better, they don’t do so well with the fact that I heard these cords sound worse than stock on one amplifier but better than stock on another. And they really didn’t help my experience that I could iterate through different power cords with any given piece of gear and hear each push the sound in different directions, liking certain cords on some gear, but not on others.

Yes, expectations shape everything, but so do physics. It’s hard to differentiate the two, and almost completely irrelevant to do so if you’re only working on a single system built for your own two ears. Try things and choose what sounds better is a pretty simple decision rule and doesn’t require anything but experimentation and listening.

This cassette talk is reminding me of my pre-audiophile pure music loving days. I had a bunch of phish shows on tape and used to carry the choice sets around in my Chevy s10. And when I was young I had one of those pioneer multi-cassette changers because... I'm not really sure why. I guess it looked cool. I also lusted quite strongly after the Nak my father's friend had in his restaurant. It was one of those that flipped the cassette for you. Such an amazing mechanism really.

Good to see this thread is back to name calling and turn-based insults.  Super productive. The only way to win the argument is to ignore and move on folks.  It's the internet, just let the other person have their perceived victory... or fight forever, those are your two options.  If only people could put this much effort into actually helping one another...
