Since our own UltraCap LPS-1.2 is no longer in production (thanks Intel for putting Altera Max10 FPGAs on indefinite hiatus!), and since our fine JS-2, choke-filtered, dual-output, 5~7.4A LPS is a bit overkill for the EtherREGEN, we are happy to recommend the following affordable and high quality discrete-regulator LPS from Teddy Pardo.

In general, you’ll experience more clarity, tighter bass, more detail, better dynamics, natural voices, better soundstage etc.


The small power supply which is provided with most types of equipment 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 Teddy12/2 power supply is based on a superior regulator called SuperTeddyReg and provides a significant improvement over 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 Teddy12/2 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 Teddy12/2 power supply noise level is very close to the zero Volt reference.

    I purchased a Teddy linear power supply to replace the power cable provided with the excellent RME ADI DAC. The sonic improvement was remarkable and more than worth the price. The main sonic improvement in my audio system was a lower noise floor which thereby allowed more micro details in the recordings to be revealed.
    The device itself is very well engineered and constructed and is, without question, suited for use in high end audio systems.

    For those in doubt: incredible sound improvement with a dac. I have a Teddy Pardo Power supply for a Exasound e38 DAC and the sound quality is twice as good and I have another TP Power supply on an RME ADI-2 DAC FS and the improvement is almost as big, and without any noise Operating. Even Teddy Pardo’s USB cable is a big plus. Other than that, Teddy Pardo’s service and efficiency are top notch.

    The power-supply arrived well-packaged and protected. I was very pleased with the metal-work, and quality level of the product in general. I am using this on an Uptone-Audio EtherREGEN device in place of the wall-wart type of power-supply. I can tell the background sound of the EtherREGEN is quieter and I think the lower registers have a little more weight. I’m sure just like any other piece of quality electronic gear, it will need some time to break-in, however right from the start, I can hear a difference. The Teddy Pardo Linear power-supply is a welcomed, cost effective and positive addition to my stereo system and improved listening experiences. Highly-recommended !

    Outstanding upgrade to the RME dac. Gave the sound a more natural realism and full body.

    I got this to replace the original switching power supply to an Etherregen. The Etherregen itself is somewhat of a happy mystery to me in the improvements it makes. Adding the TP power supply is at least as noticeable change as adding the Etherregen itself. Bass is much fuller and the soundstage widened. And that is straight out of the box for the power supply, no burnin. Just a wonderful addition to my digital chain.

    The Teddy 12/2 made a noticeable improvement to the sound quality of my SOtM sNH-10G network switch. Highly recommended.

    Excellent power supply. Well constructed and dead quiet. Ordering process was simple. Shipping to KY was about 2 1/2 weeks.

    Will be using Teddy again!
