Many of our items are honorably used for the personal system of audio critic, Mr. Ubukata.
I use TPL-2000X (Premium XLR cable) since it was released in last year between pre-amplifier and channel divider. Once I replaced other three cables between channel divider and power amplifier to TPL-2000X, the sound got obviously clear as I expected. The cables disappear from the sense of hearing and I can feel sound’s depth. In some cases, shortcomings of equipment can be appeared. These cables must stay in my system for a long time. TPL-2000R (Premium RCA cable) between phono equalizer and pre-amplifier, TPL-2000A (Premium power cable) for AC box, and TPL-2000L (Premium LAN cable) between LAN router and network hub are applied in my system. All the speaker cables were replaced to MS-DF12SP-HSE in a few years ago.
