I just started experimenting with the ERS sheets this weekend. In this short amount of time I've discovered it works best over transformers in all equipment. I've also used cloth to segregate the power supply from the processor in my DAC, a sheet over the power supply section of DAC was also usefull. I've also tried them in various other locations on all my equipment.
Thus far I've found ERS cloth to be a subtle improvement, slightly more smoothness and quietness which results in more inner detail and focus. However, I've found that too much and/or improperly placed sheets can take away texture and air sort of making things sound lifeless. One needs to be very careful with these!
i had used these when they first came out which was a big hit with tact audio users in their digtial amps. what i found out and was supported by a company that did all the work on upgrading my equipment is that these sheets actually act like a treble tone control, what they do is reduce high frequency's which then makes you seem that your are getting better bass. because of this it lets you turn up the volume on your gear more. go back to you beginning days when you had a reciever or integrated amp with tone controls. treble was boosted as well as bass. when you thought you were running out of power you would turn down the treble so it could play slightly louder . this was removing high frequency's which sounded bad at really loud levels. when my gear was upgraded i could actually take a small piece and place it on the interconnect and hear the highs just get sucked away. the problem with even putting them on transformers is that it effects everything inside your piece of audio gear. i do not use them anymore for this reason. try rf clamps on your power cords and interconnects to see which leaves the life into the music. iwill tell you were they work is placed on your computer module in your car. it removes the rfi and causes the computer not to work as hard and actually you will notice a improvement in the cars idle as well as a improvemnt in fuel economy. just put a piece about 1/4 to 1/3 the size of the computer module over the center of it. worked great in the last 2 cars i had.
There is no question that used either in the wrong places, or in too much quantity that they will effect the balance. I isolated the power transformers and power lines within the CD player and preamp with very good results. I did get an increase in treble when using sheets in close proximity to the analoge section in the CD player and had to remove these. This is why I said experimentation was the key. When using them on the inside cover of the CD player, it was most definately an improvement, with no loss of high end and overall better inner detail and image width. There is no difference in bass response on my system. Again, a cheap tweak at $20 needed to cover just the inside lid of a CD player.
I am in a quandary. Years ago I bought four sheets of ERS paper. On my Reimyo 300B amp's transformer, I initially cut a 3 by 2 inch piece. It was awful. I cut it in half and tried again. This went on until the piece was a one half inch square, but I much preferred none. I put all of the ERS in a cabinet. But still the sound was dull and had no dynamics. I sold all the ERS.
Five year later I got the Z-sleaves Ultima and put it on my main pc from the wall. It sounded much improved even though it used ERS within. How could this be? Answer, I really don't know. Is it keeping the ERS off the circuit; is it the metal in the Z- sleaves cone, is it purely where I used ERs?
