Always nice to see an old thread return.
I got a used Haley 15 or so years ago to use with the preamp and DAC. I knew nothing about it but the price was right and with all the positive comments, why not try it! And I knew I could sell it for what I paid for it so nothing to lose.
I tried it in my system against the Audio Magic I bought a couple years before. The Haley brought on a significant gain in clarity. I knew this was a great value after what I paid for the AM. I had also tried a far more expensive Sound Application device in my system and that did nothing at all. The Haley was a keeper!
I took this newly found discovery to a friend's house. He was using a Shunyata model. After a short audition/comparison, he wanted a Haley .... and got one very soon after. We both put money back in our pockets with the Haley purchase.
I bought a Dmitry a few years ago as I needed a unit with more outlets; the Haley was pushed to the HT system. A year or so later, one of the Haley's outlets failed and had melted. The cover was riveted as @dangcaonguyen pointed out. The Haley sat on the sidelines for a year as I did not know what to do with it.
Finally, last year, it was either throw it in the recycle bin, or repair it. Ultimately, I drilled out the rivets, 4 on the top and 6 on each side. I then replaced the outlet with a Furutech Rhodium outlet. I got some clips from Lowes that attach over the case's sheet metal on the inside. The clips have a threaded hole to take a machine screw. I put a clip at each of the drilled-out holes on the top and a few on the sides. I used 1/2" steel screws to secure the cover to the unit. The Haley was saved for the cost of a much better outlet and a bunch of $1 steel clips and a pack of screws.
I have not compared such devices since those years before. No doubt gains have been achieved here over the years, but for the price, the long discontinued Running Springs products are a great value.
