Shipping and cables had to be fine, but as soon as you want to use the real purpose and a second RCA cable connects increases in this cable re He stood and the audio signal is much quieter, muffled and reduces highs and lows. Therefore, for the intended use for connecting multiple RCA signals unusable to an amplifier input! For this purpose, I have now bought a RCA Soft Shift function and it works! Please stay away from these cables - the increased resistance is physically logical, but you should think before you buy it!
