Monster Power HTPS 7000 Balanced Power Unit

I’ve been fascinated by how certain tweaks like high-tech custom power cords and cables, common to high-end audio, can have a profound effect on the resolution, articulation and imaging of amplified instruments. Often the brightness we associate with amplification is not so much a matter of whether we employ vacuum tube or solid-state designs but rather a byproduct of the line noise and high-frequency grunge endemic to urban power grids.

Guitarists might want to consider a balanced power-system solution. The folks at Equi=Tech championed this approach in the early ’90s, and their products are presently a “must have” adjunct to top recording studio and professional sound reinforcement rigs. Other electronics manufacturers have taken up the balanced power torch, and now Monster Power is offering a variation on this theme, with the introduction of the Standard ($1,299) and Signature versions ($1,499) of their HTPS 7000 Home Theatre Reference PowerSource with Dual Balanced Pure Power Isolation Transformers. And what relevance does a product designed for home theater have to do with electric guitars or vacuum-tube amps? Consider this: normally when you plug in you have a positive lead with 120 volts and a negative lead with zero volts, both referenced to ground. With balanced power you have 60 volts on both leads, inversely phased, referenced to ground, and in this manner you cancel out noise artifacts.
