MSB Preamp philosophy is based on the belief that from the moment analog audio is created, every transition that is made degrades the quality. This is why we have used a passive attenuator within the Signature DAC V and a single OpAmp, to achieve the simplest, shortest possible signal path with the least possible degradation of the true music. The Signature Volume is controlled in 1 dB steps from +9 to -69 dB. Half or quarter db steps can be selected as a menu option. The Volume Control is completely bypassed when at 0 dB.
Diamond Volume Control over the signature volume control includes hand crafted shielding with lower noise measurements.
