I received my Headamp BHSE yesterday via Fedex. Justin did an outstanding job packing the amp and it arrived in perfect condition. I unboxed the amp, put in the supplied newer Mullard EL34 tubes, hooked it up, turned it on and nothing. After checking everything I realized it takes around 45 seconds for it to completely turn on. Yes in my excitement I was that stupid. I'm not good at describing what I hear but I can safely say this is the best headphone and amp combo I have ever heard. It's definitely better than any of my dynamic phones through my B-52. I may add more as I continue to listen but this amp is outstanding. My SR-007's have never sounded this good. I purchased a SRM1/Mk II amp recently to use while I waited for my BHSE and was disappointed with the way my SR-007's sounded through it. The BHSE really make the SR-007 sing. I've tried the HE 1.2B's through the BHSE but it really doesn't compare to the SR-007. Justin did a wonderful job building this thing. It is incredibly solid feeling and heavy. It does run hot so I had to put it at the top of my rack to get it more air. Here are terrible pictures.
