Lessloss Firewal Module experience?

Just read about this. Experience anyone?
From the absolute lack of response I assume this is not a great product.
Hold your horses pal ;) Im using it and its a second purchase from LL.
First thing to be noticed was total relaxation it seems that filter is doing his job so brains can rest and easily emerged in to the stream of music.It even works with amp although dac is best to start with.Highly recommended!
