Here's a description of the "Berg" modification from Summit Audio's web site. The mod was done at the factory:
"I have a TD-100 that I am using with a Bergantino IP. I heard about a modification for the TD-100 for use with this product. What is it and what does it do?
The "Berg mod" is really pretty simple. The Bergantino IP uses a +2dB nominal input level instead of the industry standard +4dB. This modification slightly lowers the output gain on the TD-100 so that you can use more of the available gain on the TD-100 without overloading the IP's input. The modification is simple, it is simply changing the value of two resistors on the output which lowers the overall output gain by 2dB. Feel free to contact us and we will assist you with the mod.
