ZETA ZERO amplifier  

We recommend for ZETA ZERO Venus and Orbital360  many models of amplifiers including tube as well solid-state as Krell, Accuphase, Mcintosh etc. Due to high efficiency of our loudspeakers you may use many available amplifiers, no matter what brand or wattage. ZETA ZERO works well with as low as 5,5 Watt per channel. Below we present a few great models. Specially we recommend perfect NAGRA Classic 50Watt class-A/100Watt - AB  per channel as  well G -BLOCK amp( 5,5Watt RMS/per channel). We also present photos of other popular amps very well matched with  ZETA ZERO.   At the end of this page we present also ourown solution-   ZETA ZERO  1175 amplifier, the most powerful. This is also  very good amp for ZETA ZERO loudspeakers.



This is analogue  power amplifier ZETA ZERO model 1175 as a final stage for luxury home cinema systems. One very small box of this clearly analogue amplifier  gives you  1175 Watt RMS of power on 4 Ohms as well on 2 Ohms.

Maximum continuous RMS power = 1175 Watt  RMS/ 4 Ohm  (may drive also 2 Ohm speaker)
Dumping Factor - as high as 1000 on 8 Ohm  !
THD= 0,007% przy 1 W ,  0,2%  do 1000 Watt
Minimum temporary load 2 Ohm, recommended 4 Ohm
Typical Dynamic  Range 118 dB or more
Frequency response 5 - 38000 Hz (on 8 Ohm) - 3dB (precisely limited by LP filter to 38kHz)
approx weight.  only 11kg
dimensions. 12cm    X    22cm  X  33 cm

Efficiency 79%

If you treat seriously the quality of sound in your  home system, do not look ONLY at power. Also other parameters are very important as for example so called but not well known for some, the critical "DUMPING FACTOR" parameter (called also DF) . This parameter should be as high as possible. It tells us how precisely is controlled the movement of the bass loudspeaker membrane. If is high,  the membrane is well drived and bass  becomes  precise, "punctual", without unwanted resonances and without so called mechanical overshoots. Movements of the membrane  become accurate. Bass guitar sounds as bass guitar, drums sound as live drums etc.

For example  if  DF = 300, it is  quiet good  for hi fi but  if is  over 1000  is  much better and is incredible in final sound effect. With 1000  or more, the reproduction of ALL dynamic specially bass  sounds  becomes more perfect  and accurate !

Below some of the most important technical parameters. Chance to its achievements this powerful amplifier is capable of driving nearly anyone high end speaker system in the World. If you are not happy with your current high-end "heavy brick" power amplifier, if your system is not powerful enough, or not perfect enough in sound- this is the very good answer for your demands.

It was simple idea for us: The power amp for ZETA ZERO speakers should be as simple as possible:  No knobs=no problems, simply  "turn ON and play" idea. Very small, very light  and easy to use in any stereo or multichannel home cinema system.

The first time bass guitar sounds  like a guitar, pipe organs sound as real instrument....voice  sounds as  human voice...The first time NO limits of power in your home cinema system at all.




The  New  generation of  ANALOGUE AMPLIFIER made for modern  home cinema

"ZETA ZERO 1175"


This is truly analogue  design  yet very small and very light . 

Inside  are NO   AD ( analogue to digital converters)  so  it  has  absolutely continuous output power characteristics   without ANY  digitalization of  output  levels (  so called steps - typical for  digital amps with AD converters).

This amplifier produces  linear power on output  as  linear analogue answer for  analogue input signal-doesn't matter how small is  this input signal.

So the sound is perfectly smooth and without distortions and no noises, doesn't matter how high or how low is input signal!

In digital amplifiers where are present DA or AD converters -distortions tend to rise  when music is going to be quiet. This is simple phenomena of digital conversion. Also in typical analogue  class  AB amplifiers  distortions  are rising when signal is  very low(because of characteristics of transistors), in Class  A  analogue amplifiers distortions are  rapidly rising when signal is going to be high  so  from A class you can NOT get to much power.

 In ZETA ZERO  1175  amp    ALL these disadvantages of  class  A, class AB and digital amps with DA or AD converters  are avoided .  Additionally  in  ZETA ZERO  1175  are   added all positive advantages of  class A, AB  and from digital ideas.

ZETA ZERO amp  works  on totally different principal (different idea) than all of previously mentioned class independently  and  it  does not has any of these disadvantages but collects all strong points together. So the sound is incredibly clear crispy, and extremely powerful (if needed because of music content)

This stack below  of ZETA ZERO amps gives total of 4700 Watt  continuous power RMS for ultimate multi-channel home cinema
