how are you even sure that your preamp is producing bass frequencies? I have a spectrum analyzer hooked up in between the cables between the preamp and the amp. It gives me a visual to see if there is bass at that frequency even playing. It’s amazing how you remember your songs having a lot of bass, but they really don’t have very deep bass. Period at the worst case scenario when I want to test something, I download a Frequency like 100 Hz or 50 Hz and I just let it play. That tells you at what volume level you need to be before your speakers will even reproduce 50 Hz. Many speakers claim that they’ll go down to 22 Hz but you have to have the volume jacked up so high to hear it , it’s not even worth saying that it will reproduce the frequency . So, I highly recommend that you get a way to visually see what your preamp is trying to reproduce. If you don’t see the fire going up, then there’s not that frequency in the recording. Pretty simple when you think about it.
How to test speaker cables by ChatGPT
I asked ChatGPT how I should go about testing "audiophile speaker cables", the response below. Not wrong.
There are different ways to test audiophile speaker cables, but here are some general steps you can follow:
-
Set up your testing environment: You’ll need a testing device (such as a multimeter) and a testing signal source (such as an amplifier or an audio player). Connect your cables to your testing device and the signal source.
-
Test for continuity: Use a multimeter to check if there is continuity in the cables. This will confirm that the conductors are not broken and that the connectors are properly connected.
-
Test for resistance: Measure the resistance of the cables using a multimeter. The resistance should be low, typically less than 0.1 ohm per meter. Higher resistance can cause a loss of signal or affect the frequency response.
-
Test for capacitance: Measure the capacitance of the cables using a capacitance meter. The capacitance should be low, typically less than 100 picofarads per meter. Higher capacitance can cause signal loss or distortion.
-
Test for frequency response: Connect your cables to a speaker and play a frequency sweep from your signal source. Use an oscilloscope or a frequency analyzer to check the frequency response of the cables. A good cable should not alter the frequency response significantly.
-
Listen for sound quality: Finally, use your ears to listen to the sound quality of your system with the tested cables. Compare the sound to a reference system with known good cables. If there is no significant difference, your cables are likely performing well.

@zlone - How does ChatGPT test for the following aspects of a cable ?
There was no mention of
These are all very important aspects of cable design and performance To explain further - take a look at this post and it will explain in more detail what goes into making state of the art cables What I Have Found Makes A Good Cable BTW: Many Cardas cable owners would have have an issue with ...
Cardas TOTL speaker cables have very high capacitance, but they perform very well I could probably line up several very good sounding cables and one very bad sounding cable and they would all have similar measurements based on the ChatGPT process - so for me - I’ll take a pass on this particular process I do agree with
Most peoples ears can tell them far more about a cable than any meter can However...
Granted, familiarising yourself with a good reference system is a good idea, but trying to compare that system to your own would be very difficult due to room anomolies, and the diferences in component selection Here are a couple of brands of cable (amongst many) that are good "performers"
