fleshler, thanks for your positive comments about the WestminsterLab Reis. The Sanders Magtech amplifier is superb, especially if high power is required. The Magtech was originally designed for use with electrostatics, given their need for high voltage on the rails (63v), yet it proved excellent for power-hungry speakers and sounded better than the standard model, given its novel regulated power supply. These amplifiers are highly recommended for high-power applications and offer that performance and build quality at an impressively low price.
For accuracy, Roger Sanders and I were partners in Innersound, a company preceding Sanders Sound Systems. After Innersound, Roger founded SSS and was the sole owner at the time of our last conversation a few years back.
PS We offer in-home evaluations for parties with a genuine interest in Westminsterlab Rei Class A monos in locals where there is no local dealer. Thanks again.
