XtremeFidelity is a very unique high-performance audio dealer located in northern New Jersey. We are different in that we focus solely on a select group of premium electronics that we feel are the best-of-breed and we do not sell loudspeakers. Our product offerings include analog audio electronics, both tube and solid state, digital products, and high-performance power and signal cabling. We are also unique in that we are one of the few dealers where you can listen to high-performance, master-level reel-to-reel tapes. These products are presented through our reference loudspeakers, the world-class Tidal Agorias, in our dedicated, home-based listening studio. Here, we offer a relaxed, informative, and most importantly, an emotionally-inspired listening experience on a by-appointment basis. Our many years of expertise with the products that we offer and our deep knowledge of premium audiophile reference systems allows us to utilize our strengths to create the perfect music listening system for the discriminating listener. We differentiate ourselves by exceptional personal service and support.

Ansuz Sparkz TC3

Sparkz TC3 replaces the current TC2 with 3rd generation "analog dither" technology pioneered by Ansuz.

Ansuz Sparkz is a noise cancellation plug for open mains sockets, mainly in power distributors. AC power power transmits disturbing noise that ‘bleeds’ into the other Hi-Fi components and impairs their ability to reproduce music with openness and fine detail on a wide soundstage. Ansuz Sparkz is equipped with Ansuz noise reduction technologies to deliver any music with more openness and speed, against an amazingly quiet background.

The TC3 utilizes an even more advanced and sophisticated version of Analog Dither that reflects Ansuz’s recent research efforts to refine this technology by calibrating the pulsating frequencies with even greater accuracy. The result is a musical authenticity that articulates itself in a strikingly more balanced and natural sound image.


The Sparkz harmonizers are designed to fit beautifully in all regular power outlets as well as in the Ansuz Mainz8 power distributor.
