I have not compared either, but I have a Dohmann Helix 1 Mk2. From reading in WBF about the CS Port TAT1, it looks like there is much more adjusting needed with the CS Port. Comparatively speaking, the Dohmann is more plug and play. I am very pleased with the sound from the Dohmann Helix 1; however, that being said, I have had very poor experience with Dohmann customer service. I’ve probably sent six emails about maintenance, upgrading parts, etc to all sorts of email addresses associated with Dohmann and never heard a peep from anyone in response.
