תיאור
Details
The TeddyNUC is an ultra low noise 19V/3.5A Linear Power Supply that can be used to replace the switching power adaptor that comes with media-PCs such as Intel NUC, Roon Nucleus, Asrock Beebox etc. The TeddyNUC provides significant improvement in sound quality, resulting from a reduced noise-floor.
The design is based on the experience gained with the TeddyCap family of power supplies for Naim Audio equipment, and uses the same technology.
Specifications are 19V DC, with up to 3.5A output current.
Compatibility
- All generations of Intel NUC, with CPU TDP up to 65W, this means i3/i5/i7 CPUs.
- Roon Nucleus, Nucleus+, all versions.
- Innuos Zen Mini – all versions.
- Asrock Beebox (S version only with i3/5).
- Small Green Computer Sonictransporter – all versions with CPU TDP up to 65W. Please note: Sonictransporter i9 is not supported.
Sound
In general, you’ll experience more clarity, tighter bass, more detail, better dynamics, natural voices, better soundstage etc.
Performance
The power supply which is provided with media-PCs is based on a technology called Switch Mode. Using this technology it is possible to create small, efficient, and low cost power supplies. Unfortunately due to their method of operation (high frequency capacitor charging), these power supplies are also very noisy, causing degradation in sound quality. As an alternative, several after market power supplies exist which are usually based on Linear Regulators. These regulators provides an improvement over the original power supply but as can be seen on the graph below are still limited in their performance.
The TeddyNUC power supply is based on the zero-feedback, ultra low noise voltage-regulator called SuperTeddyReg and provides a significant improvement over conventional feedback-based linear regulators.
The following graph shows the noise level measurements of the original wall wart power supply (red line), an alternative power supply based on a Liner Regulator (blue line), and the TeddyNUC power supply (black line). The brown line is a zero Volt reference which is actually the measurement equipment internal noise. As can be seen the TeddyNUC power supply noise level is very close to the zero Volt reference.
