World Premiere of the Zesto's Monoblocks

Thousand Oaks, CA, September 21, 2015 - Zesto Audio is proud to announce the launch of their newest product, the EROS 300 Monoblock amplifiers. The premiere will take place at the Rocky Mountain Audio Fest in Denver, Colorado USA, October 2-4, 2015 in exhibit room #1117.
EROS 300 Monoblocks

In development for more than 3 years and over 79 circuit revisions later, the Eros 300 is ready for Prime Time. "This is an amp with authority", exclaims George Counnas, President of Zesto Audio. George acknowledges there is an inherent conflict in good amplifier design because you want as much power as possible and yet you need it to finesse the most delicate passages of your music. The real design challenge is not finding a balance or compromise, but for it to be both powerful and musical".

George continues, "I always look at design from two points of view, as an audio engineer and an electrical perspective. In each design phase there is a 50/50 balance between the technical spec and listening."

George says, "What I really like about Class A power, besides being so fast and responsive, is the fact that it has the lowest distortion so it turns out to be the most musical".
The Eros 300 has plenty of power to drive your speakers with a matched sextet (6) set of KT88's and two 12AU7's producing 150 Watts per block of pure Class A power. The circuit design and power supply are quite different from Zesto's Bia 120 Stereo power amp. Counnas uses a Push-Pull and Ultra-Linear circuit topology and a more robust choke based power supply incorporating a custom Toroid power transformer. 
The Eros 300 has Auto-Bias, so it is easy to use with no adjustments or tweaking.
The EROS 300 has 2 options for your speaker cables, the 3 way binding posts or the Speak-on connector. The 4 & 8 Ohm taps provide an efficient transfer of power to your speakers. All fuses are easily accessible. The XLR input connector has its own ground lift switch to eliminate hums.
George Counnas is the founder, president and design engineer for Zesto Audio. He has loved music all his life and went from a musician, to an electronics engineer, to an audio engineer. As a young man in England, he designed vacuum tube circuits. He worked for DECCA Navigator (now Raytheon), at the time Britain's largest electronics company, as part of a research and development team designing airborne navigational systems for the Royal Air Force. So he has many years of experience designing, creating and bringing to market high-end electronic equipment.

Ice model Subwoofers have left Ohio to arrive early November


July 2015

Deep Hz Audio is excited to advise that we have a new brand of speakers to announce to Australia.

Emerald Physics build some of the most exciting and engaging speakers available today, particularly their award winning open baffle series.

I have heard a couple of Emerald Physics’ models at US audio shows and have been astonished at the incredible listening experience that these speakers provide. Effortless, powerful, full range and simply engaging is how I would describe them. Their rooms at shows are ones you just don’t want to leave and I wait to hear track after track.

Just shipped and heading our way is the top of the line EP-2.7. An open baffle design featuring-

Our speaker pair will include the passive crossover for Mid/high and the EP DSP2.4 for Low/mid. Despite their size these speakers should be suited to almost any room thanks to the Digital equalization included in the Emerald Physics DSP2.4.

We’ll give a shout out when the speakers arrive and are set up and ready for audition. If you’re in Melbourne we invite you for an audition.

Full Emerald Physics pages coming to our website very soon.

Spread Spectrum Technology (SST)

The legend of the late James Bongiorno lives on with the arrival (next month) of the long awaited Son of Ampzilla 11 stereo amplifier and the Thoebe 11 preamplifier.

The all-new Ampzilla 11 stereo amplifier outputs 220 watts @ 8 ohms and 350 watts @ 4 ohms with a frequency response of 20Hz – 20kHz +/- .1dB.
“This redesigned Son is the third generation in concept and design and features many new ideas and improvements over previous generations. However, we made sure to respect and retain the traditional circuit topology that gives the Son its revered sonic signature. The end result is a masterful fusion of classic and cutting-edge.
The new Son boasts an exceedingly low noise floor and the same power supply capacity as in our flagship Ampzilla 2000 Second Edition amplifier. Another noteworthy feature is a unique grounding procedure that insures absolutely no ground loops. The measured power output of the new Son of Ampzilla II is a potent 220 watts/channel into 8Ω (double the original Son of Ampzilla). And the listening pleasure? Immeasurable”.
For more information please see Son of Ampzilla 11 “Features” and “Specifications”.
And the all-new Thoebe 11 stereo preamplifier features a highly transparent volume control, bass and treble tone controls, high/low gain settings and a world class headphone amplifier.

Fitted with the refinements and features one expects of a modern-day preamp, the Thoebe II will deliver all of your music with style and beauty at an attractive price.
Impressive standard features include a highly transparent volume control, bass and treble tone controls, high/low gain settings and a world-class headphone amplifier. Additionally, the Thoebe II can be configured with available add-on options like a reference-level DAC and/or phonostage. The Thoebe II is about ultimate control and flexibility—the perfect preamplifier for any music source. 
Deriving its lineage from its award-winning mother, the Ambrosia 2000 Second Edition preamplifier, but boasting more than a few unique features in its own right, the Thoebe II is destined to be a classic in its own time. Invite the Thoebe II into your listening room and find out quickly what kind of “guest” has arrived—one that won’t be leaving anytime soon!
For more information please see Thoebe 11 “Features” and “Specifications”.

Headphone listeners.

For those of you who play video games and/or watch movies and TV, now you don’t have to listen in just plain stereo any longer.

The company that brought us advanced room correction for both subwoofers and full range speaker systems also produces the DSPeaker “HeaDSPeaker”Professional Level Binaural 5.1 Surround for Gaming and Movies.

The company that brought us advanced room correction for both subwoofers and full range speaker systems also produces the DSPeaker “HeaDSPeaker”Professional Level Binaural 5.1 Surround for Gaming and Movies.

The experience of watching and listening to a movie or video game (using your own current headphones) in full surround sound just cannot be matched. With this ingenious product, once heard it is fair to say you can never go back to stereo listening via your headphones again.
