Hi Boys and Girls,

I have purchased a pair of Burson HDAM module from eBay about a month ago (http://www.bursonaudio.com/Burson%20HDAM%20Module.htm). I installed them into my Rotel CDP and the improvement is worth while much better than the four Opa627 I had. It is like upgrading from a POT to a stepped attenuator if you know what I mean.

I just wonder if anyone else has tried these modules and how to they compare to other opamps.
