Perfect Path "Solutions" (PPS) eMat

With many speakers these days most amps will sound different. SO you do not start in the same place regardless of the amp. Getting that alone right is not a guarantee and can wind up with costly mistakes.

Then there is that no two speakers sound exactly the same all the time.

Not so simple. A lot comes down to personal preferences in the end.

Just don’t oversimplify things to make a case and all will be well.

Nothing is ever that hard if you really know what you are doing. Audio is particularly tricky because much of it in the end comes down to personal preference which varies widely and is hard to quantify hence all the products out there that sell.

Also, yes, a good setup will ALWAYS make a difference but even there many ways to skin the cat and even worse each cat is different to start with.

You are right it takes me 5 years to buy the right components...

But it is more difficult to learn how to embed the system than to buy the right one...

It is the reason why most people want to upgrade unsatisfied without even knowing what their system can do at his peak potential working...

I know it takes me many years to know how sound my own system.....Installation is the key....

My greatest discovery is that it is not necessary to buy costly tweaks either.... You can create them....

i sell creativity not products or design upgrade....

My best to you.....

I started in hifi back in the 70s on and off to various degrees. ~ 2008 I decided to get serious once and for all. Got some good advice here and learned a lot. Took a couple years to get it all right....right gear set up right to meet my expectations. I still dabble with things just to make sure I’m not missing anything of value to me in regards to my hifis.  Technology always moves forward and improves over time.  Harvesting its fruits effectively is always the trick.

As they say YMMV. That’s the only real truth perhaps in this whole crazy hifi world.

Agree that the key tweaks need not cost much, sometimes nothing. But again that’s just me. YMMV.

Mapman rule #1: Don’t buy anything unless you have a clear idea how it works and how you will apply it and why. My professional career has always been with various applications of technology so I am comfortable with that, but of course again as always, YMMV. Live and learn!

I am OK with your rules...but i dont buy any tweaks and i dont need to....

But i was desperate some 3 years ago....

My gear was fine but i was not in love with my system...

I begins to experiment, with vibrations controls, electrical grid noise experiment, and acoustic....

In 2 years with experiments each weeks i create some controversials devices but they all worked for me at a variable level....

My last one is a room tuner....

I am very proud of my device: in particular my grid of linked and modified Schumann generators, my "Golden plate" and my last one i like it a lot... The Helmholtz-Fibonacci organ, 3 set of 3 bricks with 3 plumber copper pipes adjusted in lenght with the golden ratio(1.6)

Cost peanuts and clean the sound across the frequencies range....2 sets of pipes are chosen relatively near one another in lenght the last set is more afar with these 2...

One set behind my 2 listening positions, and one set laterally located a few feet near the speakers...

My ideas are free to experiment with....Save for the clowns that will say that they dont need to verify by experimenting just to look at is enough....😁





My best to you....

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.
