I'm finally updating my 10-1-11 comment on the Lessloss Tunnelbridge interconnects. This won't be a full "review", but I will hit the highlights.
I've now been living with at least a pair of them in my main system for 2 months, and I've also used them with multiple components. Specifically, I've now used them with the Lessloss DAC 2004, the MBL 1611 DAC and the Lindemann 825 CD Player/DAC. All those connections went either directly to a Lyngdorf RP-1 room correction device, or to a Pass XP-20 or XP-30 preamp and then to the Lyngdorf. I also used the Tunnelbridge ICs between the Lyngdorf and Electrocompaniet Nemo and Nada amps, as well as between the amps themselves (I biamp, and the Nemo and Nada each have outputs as well as inputs). My comparison ICs were the following: Tara Labs Zero Gold (my reference interconnect), Aural Symphonics Chrono, Silent Source Music Reference, and Silent Source Silver Signature.
My initial impression when I first connected the Tunnelbridges 3 months ago was repeatedly confirmed over the next two months - this is the best cable for reproduction of bass that I've heard. It has an excellent balance between extension, definition, weight and dynamics. In fact, owners of bass-deficient systems that have been tweaked for "extra" bass will likely find that those tweaks are no longer necessary. The only comparison IC that matched the excellence of the Tunnelbridge was the Tara Labs Zero Gold. Its bass was slightly more rounded than the Tunnelbridge bass, but otherwise the they were quite close.The Tunnelbridge isn't cheap ($2500 for a 1.5 meter pair and $2600 for the power supply, though you only need one power supply for 4 stereo pairs of Tunnelbridges), but it's still 1/3 the price of the comparable Tara Labs Omega Gold.
The initial concern I had about vocals disappeared over the course of four weeks. Everything else about the Tunnelbridge sounded excellent right out of the box, but vocals took the full four weeks to match everything else. The majority of the improvement to vocals took place in the first 72 hours or play time, where the vocals became increasingly more natural. However, the vocals remained relatively forward, making them feel less integrated with the instruments than with the other cables. This gradually disappeared over the next three weeks, after which the vocals were correctly integrated with all of the instruments. I found this to be a fascinating phenomenon, different than break-in of other cables I've reviewed. In those cases the entire musical spectrum took time to settle in correctly. With the Tunnelbridge it was only the integration of vocals with instruments that took time. Go figure. Your mileage may vary.
Overall the Tunnelbridge is very uncolored and is extremely quiet - as quiet as the Tara Labs Zero Gold (which is saying a lot). This is presumably due to the power module's effect, much as the Tara's is due in part to the effect of its grounding station. None of the other cables I compared use a separate station to deliver a quiet background, and both the Lessloss Tunnelbridge and the Tara Zero Gold stood out from the rest in their ability to deliver low-level detail. I would have to say that the Tara was more nuanced, but I don't know if I would have noticed it at all if I was not making conscious direct comparisons.
Though I tried many configurations, the greatest bang for the buck with a single cable came from installing the Tunnelbridge between the DAC/CD player and the preamp or room correction device. this was also the case with the Tara, but less so with the other ICs that I compared.
Again, not cheap by a long shot, but a very good value that competes well with the upper $$ echelons of high end cables.
