Details
The Lumin Upgrade Kit, replaces the internal switched-mode PSU inside the Lumin U1/U2-mini/D2/T2 models, with an external power supply (Teddy12V/2A) and an adapter panel. Design is based on the experience gained with the TeddyCap family of power supplies for Naim Audio equipment, and uses the same technology.
What’s in the box?
The Lumin Upgrade Kit includes the following components:
- For the U1Mini/U2Mini: MiniTeddy power supply 12v/2A.
- For the D2/T2/T3: Teddy12V/4.5A power supply.
- Custom-made filler for the rear panel.
- High quality DC cable.
Sound
In general, you’ll experience more clarity, tighter bass, more detail, better dynamics, natural voices, better soundstage etc.

See “Dastereo” review of the Lumin Upgrade Kit:
“There is a naturalness in the way music is played that seems to be the opposite of “digital” playback” (LINK)
Superb out the box!
The kit is well built and works great. Customer service is excellent as well.
Installation was easy (you don’t need to cut all the four cables from the orginal power supply), but the online manual wasn’t correct in the whole way.
I put the nuts to the inside and added some washers.
Also the cover for the orginal power supply could be a bit better.
Sound: I don’t know, but it seems that the SQ becomes a little bit better (more substance in the bass), but it’s hard to find this out without a really A-B-test.
