Кстати птичка на хвосте принесла - характеристики кабелей это почти религия, кабели известных фирм практически не отличаются друг от друга
As a rule of thumb, we recommend spending as little as you can to get the job done right, but no more than 5-7% of your total system cost into cables and interconnects.
Analog interconnects are also quite important since they interface high impedance since they interface high impedance connections, usually greater than 10kohms for amplifiers, preamps, etc. It is important to choose twisted pair cables or shielded coax which provide reasonably low capacitance, good shielding , and solid terminations. An excellent example of a cable well suited for audio applications is a shielded twister pair used for microphones such as the Belden #8422.
If we assume the output impedance of your source component (IE. CD player) is around a hundred ohms up to several kiloohms, then you can get away with an interconnect of up to a few hundred picofarads of capacitance and still yield a 3dB point well above 100kHz, or flat within the audio bandwidth 20Hz to 20kHz, based on the relationship of: frequency = 1 / (2*pi*R*C).

P.S
Any advices or experiences?
I need 4 m cables and have а 300$ budget.
Thank you for your help and advices.
