The Q5 plugs into that supply and, according to SteinMusic, gives the music more headroom and freedom. It takes one outlet, there's nothing to wire in, and you can add more as you listen.\u003c\/p\u003e\n\n\u003cblockquote\u003eTune the mains, and the music gets room to breathe.\u003c\/blockquote\u003e\n\n\u003ch2\u003eThe Design\u003c\/h2\u003e\n\n\u003cp\u003eSteinMusic calls the Q5 a Mains Quantum Organizer, a combination of electronic circuitry, power purification, quantum physics, and crystal technology. SteinMusic says these parts work together to influence the power grid, the foundation of all the music a good audio system can reproduce from a recording.\u003c\/p\u003e\n\n\u003cp\u003eThe electronics carry the benefits of SteinMusic's quantum physics and crystal technology onto the mains. They include a classical parallel filter, and SteinMusic explains why it built this one differently. Filters can remove high frequencies and always have dielectric losses that take energy from the music. SteinMusic says that can help a system that sounds too bright, while a balanced system can lose subtleties and nuances. The goal is not to add a component that compensates for errors elsewhere, so SteinMusic designed a filter with a very high Q factor that shows only about 3 dB of attenuation at 10 MHz, which keeps losses extremely low. The rest of the circuit treats both half-waves of the mains equally, using symmetrical pn junctions. SteinMusic also uses electrically activated crystals with a very uniform atomic lattice, which it says, together with its quantum physical approach, can influence the mains in a positive way.\u003c\/p\u003e\n\n\u003ch2\u003eHow to Use It\u003c\/h2\u003e\n\n\u003cp\u003eSteinMusic recommends at least two Q5s in an audio system: one in the power strip or after the power conditioner, and another in a free outlet elsewhere in the listening room. Some customers use many more, spread throughout their homes, and report significant positive effects.\u003c\/p\u003e\n\n\u003ch2\u003eWhere It Fits\u003c\/h2\u003e\n\n\u003cp\u003eThe Q5 suits systems where you want to work on the power itself without adding a filter in the signal path.

Alongside the fuses' effect we heard more low-level detail, better phase detail (harmonics close in frequency separate instead of blurring), and a wider soundstage. In our experience they've surpassed the fuses as a system-wide improvement, possibly because they affect everything downstream on that outlet at once.
