Taiko Audio no longer offer this upgrade, as they sold out (cost was £800).  The top and bottom alu case covers are replaced with solid copper which absorbs electromagnetic radiation.  The bottom plate has the same vibration reducing pattern as Taiko's daiza isolation platform, the upper place has a square insert of panzerholz.  You also get three new anti-vibration feet with the kit which include tiny panzerholz inserts.

USB Firmware has also been updated, so no drivers needed - works automatically in Windows and Linux upto DSD512.

Perfect condition, boxed and will also be supplied with the original alu case covers should you ever want them.  

Asking £2500  + shipping or collection in person (socially distanced).
