    "best_for": "Studios and engineers who want a matched pair of classic-style large-diaphragm tube microphones for stereo recording — X\/Y coincident (both cardioid), A\/B spaced pairs, or mid\/side using the U48's figure-8 against the U47's cardioid — on sources like orchestra, choir, chamber groups, drum overheads, acoustic guitar, piano, and percussion, while also covering flagship vocal duty (the set's mics share the M7 capsule, VF14K tube, and BV8 transformer of Telefunken's U47 reissue).",
    "who_should_skip": "Buyers who only need one microphone (the U47 and U48 are sold individually with their own power supplies), anyone wanting phantom-powered simplicity (these require the external M940S dual power supply and dedicated tube cables), or engineers needing more than two polar patterns per mic or headroom beyond the rated 127 dB max SPL at 1% THD.",
    "fit_notes": "The two microphones are electrically the same design and differ only in pattern pairs: U47 = cardioid\/omnidirectional, U48 = cardioid\/figure-8 — the figure-8 is what unlocks M\/S technique. Capsules are tuned to each other and transformers\/tubes tested for matched gain and frequency response, which is the point of buying the set over two separate mics. Each mic is 240 mm long, 620 g, with 24.5 mV\/Pa sensitivity and 9 dBA self-noise per the manufacturer. Everything travels in one FC10 locking flight case with two WB40 wooden boxes and two 25 ft ACX-7 tube cables.",
    "watchouts": "Minor spec discrepancies between sources: the manufacturer lists each mic at 240 mm x 60 mm and 620 g, while retailer listings state 9 3\/4 in (approx. 248 mm) x 2 1\/4 in and 22 oz (approx. 624 g) — manufacturer figures are used here. The retailer-listed studio-set contents (M940S dual supply, FC10 case) differ from the single-mic packages on the manufacturer's site (M940H supply, FC40 case, M740 shock mount); notably, neither verified retail listing nor Pro Audio Design lists shock mounts among the studio set's included items even though the product photo shows one — confirm with the dealer before purchase. No manufacturer part number (MPN) is published; the SKUs found (Economik 11710, Pro Audio Design SYTM-041) are dealer-internal. Listed at 29,895 CAD and in stock at verified retail listing at time of research.",
    "verification_questions": ["Which connections, drivers, operating systems, and sample rates are supported by this exact revision?","What cables, mounts, power supplies, or licenses are included?","Is the current retailer listing new stock, demo stock, open box, or special order?","Is the item still in stock at the displayed price, and what is the complete delivered cost to the intended destination?"]
