For checking audio sound quality (power cable, speaker cable, speaker, insulator, amplifier, PC, USB cable, SPDIF cable, ground, wall material, cellulose fiber sound absorbing material in the wall, ceiling height, etc.). Youtube. when I connected OYAIDE Oyaide power cable TUNAMI GPX-R V2 1.8m to PC and FURUTECH's The Empire to audio amplifier, the sound quality was flatter from bass to treble than Oyaide, with higher resolution, and the sound and voice of instruments were raw and realistic The sound quality was excellent. If you can afford to buy TIGLON - MGL-DFA10-HSE or TIGLON - TPL-2000A Premium AC Cable or Power Code - Acoustic Revive, it may be better sound quality.

I'm not sure how much I'd be willing to pay for it.

I have replaced two power cables, one for the audio amp and the other for the PC, with various cables ranging from a few thousand yen to about 25,000 yen used.

1. the master sound source is "Whose Flowers Are These" by STU48 on Youtube, and that the high notes don't sound too loud.
