The problem is that there seems to be no mention of actually giving the SP3's a listening test against the generic cables. There are things that are not yet measurable. Examples are soundstage, musical realism, the 3D roundness of the image, etc. One must use their ears to experience these things. The ears are the final judgement. We have tens of thousands of customers, in over 80 countries who have bought our cables. They had a 60 day return that began when received. They tried them against their other cables and kept ours. You better believe that if they did not hear a difference, they would have returned them for a refund. Their testimonials bear witness: https://www.morrowaudio.com/pages/reviews Measurements are only a part of the picture. The ultimate test is ones musical enjoyment, with the ears being the final decision maker. Peace...

I agree that ears should be the final judge. I'm glad to see you support the use of blind testing in audio. That's what you're saying, right? Right?

Nope. There's absolutely no way you have tens of thousands of customers . I know (knew) quite a bit about audiophile cables brands... Still, I had never heard about your brand before this review.

This is a niche market in the niche market. As your bullshit claims about sound, you are actually lying.

Electrical measurements could certainly replace the mic ones. More straightforward & repeatable.

Let's compare the frequency response of the SP3 against generic cable:

@amirm I know everyone appreciates your speaker cable measurements, and it's clearly generated a lot of discussion here.

One thing I wanted to ask you about is what load was used to take your FR measurement. The reason I ask is that multiple AES papers, all amplifier measurements in Stereophile, and several ASR members, have reported that with a typical loudspeaker load (i.e. a reactive load with varying impedance vs frequency), there should be 0.1-0.4dB (ballpark) fluctuations in FR over the audible range based on the DCR/inductance of the cable + speaker/crossover. Whereas, if your load is a simple non-inductive resistor, then you would not see any fluctuations, similar to the measurement above. The problem is that if you're using a non-inductive resistor as the load, FR measurements will NOT show any deviations caused by the speaker cable when an actual loudspeaker load is used.

To give an example, here are Stereophile's measurements of the Benchmark AHB2 frequency response into purely resistive loads (the flat colored lines) vs a simulated, reactive loudspeaker load (black line).

It is my hope that when providing loudspeaker cable measurements, you would consider measuring them into a simulated loudspeaker load (or to an actual representative loudspeaker, perhaps at low volume).

This is all the snake-oil proof I need.

Our measurements show that losses in these cables is incredibly small and no different than a generic, near garbage cable that I build to compare.

While you have demonstrated several times that a good premium cable is functionally at par with a good generic one, I have strong reason to suspect that an "entry level" cable from a manufacturer like Audioquest or Inakustic is substantially _worse_ than a good generic cable. I tried their cheap interconnects and they just ruined the sound for me beyond a pale of doubt. Given (from your reviews) that it is easy and inexpensive to make a good cable, I suspect that these companies might be doing & implementing research how to _worsen_ the quality of their cheaper cables so that folks would really hear the difference when they upgrade.

It would be great if you find time & motivation to do such test with entry-level cables from these firms. Could be another PS Audio moment

Well, if you still have them, please send them in. If they are really that terrible, we will find out why. Don’t be surprised if we find absolutely nothing though.

Don't trust your ears. You expect badness. You get badness. Nobody is immune to psychoacoustics. Nobody!
