Nope it doesn't and I can't I can't tell you why but I can tell you about what happened to me. I had an amp plugged into an industrial 1.8 KVA Topaz Isolation transformer and there was a spike/surge that occurred over this past weekend. Now the left channel of the amp is out and the left speaker is blown. I was breaking in speaker cables and was using an Ipod as a source directly to the amp. It could have been worse had I just not had that specific set-up for the speaker cable break-in.
The good news is that with Isolation transformers in place I did hear an improvement in my sound systems. A lot more clarity and detail.
