About the 727
The Soulution 727 is a Swiss reference preamplifier designed to minimize noise, phase error, common-mode interference, and distortion. It uses a dual-mono architecture, a wide-bandwidth input/output stage, and an advanced relay-switched volume control. An optional phono module adds MM/MC support with adjustable gain and loading. It replaced the 725 and is presented by Soulution as a top-tier 7 Series preamp; current official and retailer specifications list it as a production model rather than discontinued.
