I ordered TechDAS Air Force Zero at the end of 2019. The expected delivery time was on August 2020. The designer Nishikawa san wanted to install every Zero personally to make sure it performed to the highest standard. COVID and travel ban had stopped TechDAS team to come and install my Zero. Nishikawa san promised after the pandemic, he will come and inspect every Zero to ensure its best performance.
Unfortunately, Nishikawa san passed away in June this year, but TechDAS still wants to fulfil his wishes. During the current Hong Kong HiFi Show, they came to my place to check and fine tune my turntable. The chief engineer, Hajime Shimizu, carefully measured every parameter and set it to factory recommended values. After a final listening test, he was satisfied that the Zero was up to his standard. I was very grateful for their efforts and professionalism. There is audible improvement after fine tuning. There are things that are overlooked before, such as tension on the belt and ride height of the turntable. Their expertise is no doubt very valuable.
