Hi, I am selling my Holmes Powell headphone amp for 1/2 price. The Holmes Powell recieved the 1999 Golden Year Award. It's not the best but its 2nd best rated by The Absolute Sound magazine. The best is the new Esoteric Audio Research HP4 headphone amp. Email me for details: [email protected] More info: http://headwize.com/ubb/Forum5/HTML/000064.html And also search the forum for holmes powell.
