    "watchouts": "Product identity: the catalog title says 'Preamp \/ DI' but all sources (manufacturer and retailers) describe the LOCi strictly as a phonographic playback preamplifier -- confirm intended use before purchase. Price conflict: verified retail listing lists CAD $21,840 while the manufacturer lists USD $15,500 -- verify current price and configuration. Manufacturer notes it is a custom order with an 8-12 week lead time. Input loading is user-selectable and factory-set, so specify your cartridge requirements when ordering.",
