Notable use: Robert Lang (Robert Lang Studios) quoted on chameleonlabs.com praising low noise and clarity (shared quote used on base 7603 page)
Notes: 1073-style Neve-inspired preamp; variant of 7603 fitted with UK-made Carnhill input/output transformers in place of Chameleon's own custom transformers (per third-party review, adds ~$400 vs base 7603). Same circuit family as 7603, listed as separate SKU/product on manufacturer site so kept as separate row. price_usd is street price at Vintage King (vintageking.com/chameleon-labs-7603-xmod-mic-preamp); chameleonlabs.com does not publish price.
