Wiim Ultra Upgrade

The Wiim Ultra Power Supply Upgrade replaces the internal switch-mode power-supply in the Ultra streamer, with a Teddy Pardo Audio high performance external power supply.

This upgrade process is not DIY friendly, and thus can only be performed by Teddy Pardo Audio.

The result is a big step forward in the sound quality of the, bringing it very close to the level of network streamers costing 3 times as much.

Inside the MiniTeddy Power Supply

The MiniTeddy Special Edition, scheduled to start shipping on 09/2024, is a complete redesign of the standard edition. It is based around our new Tedinator discrete voltage regulator.
The Tedinator is a fully discrete design, based entirely on ultra low noise JFET transistors with no IC chips. It is the result of countless hours of development, testing and listening. Its design is inspired by the writings of great minds like Walt Jung and Nelson Pass.
With the new Tedinator and the new circuit around it, we were able to achieve impressive new levels of low noise, low output impedance and fast response time, resulting in a highly involving sound, perfectly timed and with no apparent phasing errors, hence our new slogan : The Art of Silence.

The design features:

• Fully discrete design, based on JFET and Bipolar transistors;
• Multi-device output stage, for reduced output impedance and better load handling;
• Oversized transformer with 60VA capacity;
• Main capacitors from Kemet (Aerovox UK);
• Tantalum capacitors from Vishay (Israel);
• Electrolytic capacitors from Panasonic (Japan)
• Built-in ground-loop killer, to prevent ground-induced noise.
