minimum capacity and impedance cables

Hi Friends,
I am looking for cables to connect the amplifier to speakers with minimum capacity and impedance. I have an amplifier from the Polish manufacturer Baltlab which works best with the Red down Nordost. however, they are too expensive for me. is there any cheap alternative? the amplifier is very neutral and every change of cabling makes a difference.
I will be grateful
 
Thank you for your response. However, in this amplifier you can listen to the influence of the wires. same as I was making RC from the Supra Eff-i cord. My brother laughed too until he heard them. After 30 seconds of listening, he immediately asked how much money he wanted for the RCAs. However, my friend did not hear such a big improvement on a cheap amplifier and loudspeakers. probably every system reacts differently.
 
There are times when cable resistance can make small differences, especially with long runs of thin cable. However it's even more difficult to hear such small differences in bass than at higher frequencies.

It's also a simple and inexpensive matter to fix.

Just use thickish cable and not very long.
At the lengths mentioned, a couple meters, most any 18ga and thicker cable will do.

Just browsed the Nordost site, sounds very snakeoilish "Audiophile" oriented for my taste.
ZERO data, tons of "reviews" and "testimonials".
Free sample:
“Nordost Valhalla V2 Ethernet offered a different, clearer, and more focused imagery, sounding less like a mechanical pulsating narrative and more like a tenacious non embellished sonic momentum.”

IF that Polish amplifier is so sensitive to cable used, it might be marginally stable.
 
The disadvantage that must be mentioned is the relatively high output impedance for a transistor circuit. According to the manufacturer's data, it is 0.4 n, which with the use of nominally 8 ohm loudspeakers gives a damping factor of 20. This value is closer to tube amplifiers and despite the large power and reserve of the power supply, it suggests careful selection of loudspeakers

The cable needed is easy to calculate. Knowing load resistance and mean power, you can estimate current and voltage. So, assume a maximum loss in the cable: 0.1, 1, 2, 5% of the power available for the load or whatever value is desired. Thus, estimate cable resistance from cable drop. Take any reliable cable chart and look for a cable whose resistance (resistivity times cable lenght needed) be lower than half you estimated (taking into account send and return cable resistance). Go to a supplier and buy such a cable. Return home, hook it to baffles and amp, power the audio set on, play your favourite vynil, go for a dosis of good whisky on the rocks and enjoy.

I haven't musically trained ears. I can't take difference from, example, la432 and la440. Certainly I can listen few amounts of distortion or intermodulation in amps.

But l have mistrust of who say that can ear a difference in the "sounding" of a piece of cable or between A and B kind of capacitor. Surely I am wrong.
