TDC-01 Dia

Diamond Cantilever MC Phono Cartridge

TechDAS launches the TDC-01 Dia employing an innovative diamond technology for its cantilever

We are pleased to introduce the TDC-01 Dia, the new flagship phono cartridge in the TechDAS TDC01 cartridge line. Diamond is known as the best and ultimate material for a cantilever. Taking advantage of a diamond’s sonic transmission speed, this MC cartridge has no loss of energy and picks up even the most minute signals. It allows delivery of every detail embedded in the groove, from the most subtle nuance to the most powerful slam, thereby achieving an unprecedented level of analog playback.

The TDC-01 Dia has a tapered pipe diamond cantilever that has employed titanium for the signature egg-shaped housing and housing base. It was very challenging to machine diamond into a tapered pipe shape, and asťer three years of research and development, we finally made this happen with a state-of-the-art laser processing technology.

Major features

- The world’ s first tapered pipe diamond cantilever in the industry with an extremely high rigidity and low mass.
- Compared to conventional cartridges, the diamond tapered pipe cantilever has a higher speed to transmit vibration from the record groove to the coils without damping.
- High signal to noise ratio to deliver more details with clarity.

We are thrilled to announce that the TDC01 Dia cartridge has received the Stereo Sound Grand Prix Award 2024. Here are some quotes from the Grand Prix special issue
(2025 Winter) of the magazine:

"The new TechDAS cartridge is formidable that its cantilever is made of diamond machined in a tapered and tubular structure."

"Dia cartridge realizes an unrivaled resolution that no other cartridge could achieve."

"It delivers such reality that it would be a true you-are-there experience, and you would feel as if this is actually happening in front of you. At the same time, the sound is so natural as it has nothing artificially emphasized. Probably this is because of its hollow tubular structure, which allows not only rigidity but also a superb flexibility."
