Jumping in very late here, but I just registered and am new to the forum. I was searching for comments on the Tunnelbridge and saw this string.
I have a bunch of the Lessloss stuff (DAC 2004, DFPC Signatures, Firewalls and Blackbodies) and have had a chance to compare it directly to a wide variety of other products. I can tell you that their stuff is quite good, and I have not had an issue with shipping or support.
I'm currently deciding whether to check out the Tunnelbridge. If so, I will compare it directly to the Tara Labs Zero Gold, the MIT Orable MA-X, and the SilentSource Music Reference. If you order the Tunnelbridge I'd appreciate your comments.
