Hi.
I've find that link: http://tad-labs.com/jp/consumer/accessories/
These accessories are not available on the main site.
They look very well and the design seems apropiated.
Would be interesting to know how they improve the sound.
Wellfloat/G CLEF Acoustics is the OEM of the audio board. From my understanding, they also produce for CEC, airbow.
I think the Finnish Birch finishing for TAD is unique from others.
I am using wellfloat audio board and very happy with the improvement
