How to setup the AudioValue VERTO to achieve true high-performance from your Dynamic, Planar Magnetic and Stax headphones from one system.
Helmut Becker of AudioValue has designed a unique passive device called the VERTO. The VERTO will allow you to use your existing components and setup one system that will be capable of driving your dynamic, planar magnetic and electrostatic headphones to peak performance.
The VERTO is a passive device (no power supply required) powered by the signal from the power amplifier. This allows the VERTO to be transparent as it will yield the true sonic signature of the power amplifier and other components you use in the system.
This is a huge advantage over dedicated amplifiers for your Planar Magnetic or Stax headphones as they can be very costly and many are overpriced yielding less than optimal performance.
But with the VERTO you have no limit as you may use it with your favorite high-performance power amplifier(s) and other components to achieve superb results driving any type of headphone.
Below is my recommended system setup with the VERTO. In this configuration there are no sonic compromises in terms of which headphones you use with the system as Dynamic, Planar Magnetic and Electrostatic headphone all perform superbly.
First off, to achieve the absolutely top performance from the VERTO and the rest of the components in your system it is extremely important to use vibration control and properly designed system cables for all the components in the system. These two very important and over-looked “components” will for lack of a better term “double or “triple the capabilities of the collective components very notably improving the overall system performance.
See the following information on the www.mapleshaderecords.com website:http://mapleshadestore.com/feedback.php
The large front Mode Knob on the VERTO allows you to change the impedance depending on the design of the headphones (Dynamic, Planar Magnetic or Electrostatic):
8R (8 ohm resistance) is for Dynamic Headphones.
32R (32 ohm resistance) is for Planar Magnetic Headphones.
ESH (Electrostatic Headphones) is for the Stax or similar headphones.
With rigorous testing I have determined that the VERTO drives the Stax and the higher impedance HiFiMan HE5/6/1000 and Audeze headphones extremely well when both types of headphones are set to the ESH setting. With the HiFiMan and Audeze headphones, it is somewhat splitting hairs as they still sound great on the 32R setting (the intended planar magnetic headphone setting) but I eventually heard slightly better dynamics with them on the ESH setting. Try both as you may find both to be equal or the 32R setting better suited for the planar magnetic headphones you use in your particular system.
Another important aspect of the VERTO I have learned while testing is the lower impedance Audeze headphone and all the Dynamic headphones did perform better than when connected to the VERTO when instead using a high quality headphone amplifier (which can produce 1 watt or more of output) connected to the pre-amp outputs of the high quality integrated tube or SS power amplifier – the same amplifier in which the speaker outputs are connected to the speaker inputs on the front panel of the VERTO.
So here is my recommended setup based on extensive testing of all the combinations available from the front panel of the VERTO:
– Choose and use any source(s) you prefer: CD, Vinyl, Streamer, Reel to Real etc.
– Connect your source(s) to one high- performance integrated tube or solid state power amplifier.
– Use the speaker outputs of the integrated power amp you have chosen and connect your speaker cables to the speaker inputs on the front panel of the VERTO.
– Your system is now setup so you can connect your high impedance Planar Magnetic and the Stax headphones to the front panel of the VERTO. The volume will be controlled by the integrated power amplifier.
– Now use your headphone amp to drive all your Dynamic and low impedance Planar Magnetic Headphones by doing the following. If your integrated amplifier you have chosen for use with the VERTO has a tape output, connect your headphone amplifier with interconnects to the tape outputs and use the volume control of the headphone amp. to make volume adjustments. If your integrated amplifier does not have a tape output, connect your headphone amplifier with interconnects to the preamp. outputs of the integrated power amplifier. If you are using the preamp outputs, set the volume control on the integrated amp. at a low setting and control the volume by the headphone amplifier volume knob.
– Now connect your headphone amplifier with interconnects to the preamp. outputs of the integrated power amplifier you have chosen for use with the VERTO. Use your headphone amp to drive all your Dynamic and low impedance Planar Magnetic Headphones.The volume can be controlled by the headphone amplifier and/or the integrated power amplifier.
You can try any headphone amp. you prefer (other than one that produces an output of 1 watt or higher) and test the results as the performance of this headphone amp. in your system might prove to be excellent as well.
