DESIGN PHILOSOPHY

Conventional amplifiers have serious problems when forced to drive electrostatic loudspeakers. Roger Sanders has developed the first amplifier specifically designed to drive these unusual speakers.

Electrostatic loudspeakers (ES­Ls) are very differ­ent from conventional mag­netic speakers and place unusual and difficult demands on the way amplifiers deliver power to them.  A magnetic speak­er presents a resistive/inductive load to an amplifi­er, while an ESL appears mostly as a capacitor. Roger has developed both the ESL amplifier and the Magtech amplifier to meet these demands.

BEHIND THE SCENES 

All electronics (boards and chasis) are manufactured in Conifer, Colorado.  

CNC milling machine cutting out ESL amp faceplate.

Heatsinks start out as solid aluminum 3 1/2 inches thick by 20 feet long. The aluminum block is then extruded to create the fins and it arrives at Sanders factory in 20 foot long extrusions. They are then cut and milled on the CNC milling machine along with all holes drilled and tapped before they head out to local company for bead blasting and then off to be anodized.  We use local small businesses whenever we can.

Sanders Sound Systems Cables & Interconnects

We believe that the speaker manufacturer knows how to get the best sound from his speakers and that we should not interfere with his design. At Sanders Sound Systems, we make no extravagant or false statements about our interconnects. What we DO claim is that they are the very finest quality and are superbly engineered. We don't claim that they sound better than any other well-designed interconnect.

Electrostatic Speakers

He quickly appreciated the superior performance that a massless electrostatic offered over conventional magnetic speakers with regards to low distortion, lack of resonances, and incredible detail. To eliminate the usual customer complaint about having to buy two amplifiers to operate bi-amped speakers, Sanders supplies a bass amplifier as part of each speaker system.

Sanders Sound Systems Preamplifier

The goal of a true audiophile grade preamplifier is to offer gain, switching, and other conveniences, while at the same time passing the original signal downstream without adding distortion, noise, or a sonic signature of its own. The display continually shows the output level of the unit and switches automatically to show level differences between channels, when you adjust the balance, or when you adjust the input levels.
