Okay, I saw no reason why not to try this tweak. I ordered two from Amazon. I chose a $40 model simply for aesthetics. I have been going back and forth both with vinyl and hi-res streaming. I probably should not post after 1 hour of listening and 2 glasses of wine but I truly do feel these things are making the music more defined. The instruments with them seem more focused and the subtle sounds pop more. I suppose the real test will be when I can arrange a friend to come over to control their power and see what I say then! This takes me back 20 years when I added my cold-air intake to my Integra GSR.....it felt like about 7 Hp on the butt dyno. There's an expression we should implement into the audiophile world. Our listening butt dyno.....love it!

I got 2 of these from Amazon...careful that free returns are applicable. I charged them up, turned them on and holy moly.....they do help with my system. What I hear is clarity....space between instruments, a definite difference in upright and electric bass, wider soundstage...you know...all the good stuff. At first I thought it might be increased brightness, but no....it is still the same in that regard. I still can't believe it, and will listen again tomorrow (saved the packaging for the return)...but today, I'm about to keep them.
