Perhaps seldom if ever on Audiogon, one of the best Headphone amps and preamps made, the Eddie Current Balancing Act. These are custom made amplifiers by Craig Uthus of Eddie Current. This beautiful amp was purchased direct from the manufacturer about 1 ½ years ago. I bought it expecting to be moving into a condo and wanted the best headphone amp available. As it turned out, I remodeled a home and simply don’t use this amp. It has been in the shipping box in my back bedroom for all but the last month. It has less than 10 hours on it so it is probably not yet broke in. It is a visual and audio work of art and needs a good home to be appreciated. I personally only used it briefly as a headphone amp and never used it as a preamp. I have the original boxes and the setup instruction sheet. If you are a headphone enthusiast you will undoubtedly know of this amp. If not, please visit their web site at www.eddiecurrent.com. This amp uses the 300B’s and has the upgrades to silver windings on the secondary transformers and Teflon sockets. The headphones in the picture are NOT included. From the manufacturer:
“The Balancing Act brings a new level of listening luxury to high-end audio. Painstakingly created with custom features built into the unit for the discriminating audiophile, the BA delivers sublime listening pleasure. It is also designed to serve as a preamp and will drive balanced lines for optimum speaker listening enjoyment. When it’s all about the music, the Balancing Act is your performance soundstage. Even the hardest-to-drive headphones will sound simply amazing.
