The Mainz DTC Power Bar is a massive upgrade to the Mainz D8 Power Bar mistakenly called a Mainz 8 DTC. It was designed by Michael Berresen who has been responsible for the design of products from Aavik, Ansuz, Berresen, many Raidho speakers and Nordost cables.
The Mainz DTC Power Distributor has the same powerful impact that Ansuz DTC power cables have produced. It will supply a steady flow of current to even the most demanding High End system. The photo of the inside of this device shows the complex technology employed in the DTC power bar. The Mainz DTC could be rated Mint. I'm being conservative by calling it 9 out of 10.
