GOLDMUND - Swiss Made High-End Audio Equipment

The Goldmund Amplifiers are using a very different approach in the design of their power supplies than usually made in Hi-Fi amplifiers. In order to get the maximum speed in transients, the filtering capacitors are reduced to a minimum and the transformers are smaller but faster models.

With this specific topology, the capability of the AC line is critical to insure the amplifier maximum performance.

The first and best principle is, when possible, to dedicate a direct AC line for the Power Amplifiers, or even better, for each of them if several are used in the specific installation (mono blocs, multi-amping, multi-channel, etc…).

The quality of the dedicated power line installation is critical. Not only in it’s section, but also in its continuity (no junction boxes), direct connection to the house central distribution (dedicated line breaker of highest possible power), and speed (4 wires mounted in cross + ground is better than 2 wires + ground and thick wire is better than multistrand even if section is smaller).

The dedicated power lines must be, as much as possible, directly feeding the amplifier without any extension cord or multiple connecting boxes.

The use of Goldmund Powercord to connect the amplifier to the wall plug is greatly improving the sound.

The most sophisticated installations use wall plugs where arriving wires are soldered to the contacts, rather than tightened, but this may be against local regulations in some countries, be careful.

If your installation has a Goldmund AC-Curator Line Conditioner, use the 4 high power outlets to connect the power amplifiers. Never use any other line conditioning device, they may ruin the sound quality of your power amplifiers since most designs are slowing down the current fluctuation, destroying the transient capability of a Goldmund amplifier. (See also the Grounding Schematics).

Various devices have been designed to help filtering the AC line and most are improving the sound quality of a system.

However, due to the specificity of Goldmund electronics, and especially power amplifiers, very few of the existing devices may work ideally for the Goldmund equipment. If you own one of such device (except the Goldmund AC-Curator), do not use it for the power amplifiers but only for low power devices.

A single Goldmund AC-Curator may be feeding 4 power amplifiers and 6 low-power units (preamplifier, CD player, D/A converter, etc…) with optimum sonic quality.

If you want to use another equipment than the Goldmund AC-Curator for the low power equipment in your system, we strongly recommend to use a separate one for each piece of equipment. The maximum sonic improvement is brought by the isolation created between the different devices (like the six isolation transformers in an AC-Curator are doing). Any single device is usually using one transformer only and will not bring the necessary isolation.

If possible use only parallel-filtering principles rather than serial devices which are very often damaging the sound quality.
