USB power supply?

Power supplies are the most important part of any audio system and this is what sets apart really live sounding systems. The source is also extremely important. The USB data should have no errors and low jitter. A fast-reacting, low-noise supply is required. Most linear supplies don't meet this criteria, with one exception, the Power Block from Empirical Audio. It is also a common-mode filter.

The Power Block uses a toroidal transformer which provides up to 5 amps at 5V. It is extremely low noise and very fast reacting, utilizing a Hynes-type voltage regulator. Hynes regulators beat all other regulators due to their unique topology. The Power Block was primarily designed to be used with the Empirical XMOS USB interface that is in prototype stage right now, but can be used with any USB interface. XMOS interfaces improve significantly. It runs on 117VAC or 230VAC. Here are photos and more info:

Jazz - I can charge 50% more for my products to pay for advertising like other companies, or I can help a lot of folks on this forum (which I do every day) and talk about my products and charge less for them. Its the customer that ultimately benefits.

There are a lot of folks that seem to think they are an expert on this and other forums, which leads to a lot of misinformation. This is why I post.
