Palikrovol..why don't you go to the source and ask that question. Go to the Violectric website and ask Fried Reim what he thinks about the pre-amp. I know it is in his best interest to sell you something ..but I found Fried to be very low key and knowledgable without out an attitude in anyway. Just a thought. More info is better from a variety of sources....but Fried knows his equipment and is a straight shooter. (There is a little language barrier there, but he handles that very well, too).
Hope that is helpful.
