    "best_for": "Vinyl listeners running moving-coil cartridges who want autoformer-based loading (25-400 ohm taps) instead of resistive-only MC loading, owners of multiple tonearms or turntables (three independent phono inputs), and anyone who wants to dial in cartridge loading precisely — resistive loading to 47 kOhms and capacitance adjustable 10-1100 pF in 10 pF steps, with 50-65 dB of switchable gain. Its stereo line input plus volume-controlled 75-ohm variable output let it double as a minimal tube line preamp driving a power amp directly, with RF remote volume\/mute from the listening seat.",
    "who_should_skip": "Anyone needing balanced XLR connections (all inputs and outputs are RCA), buyers wanting a compact single-box phono stage (it is a two-chassis system — a 19-inch-wide main unit plus a separate 18 lb power supply with an umbilical), or listeners with a single MM cartridge and no interest in loading experimentation, for whom most of the Steelhead's adjustability and cost would go unused.",
    "fit_notes": "Plan rack space for both chassis: the main unit is 19 x 3.5 x 15.5 in and the PSU 13.5 x 4.5 x 11.375 in with a roughly 5.5 ft umbilical (Elusive Disc figures). The fixed 150-ohm output feeds an existing line preamp; the variable 75-ohm output drives a power amplifier directly, and the REMORA RF remote works through walls and cabinetry. Tube set is two 6922 gain tubes plus four 7044\/5687 buffers; a SLEEP standby mode conserves tube life and muting relays short the outputs at power-off. Mains is factory-set for the destination country (120-240 VAC).",
    "watchouts": "Source conflicts to note: the manufacturer specifies the resistive input as 100 ohms to 47 kOhms, while Elusive Disc lists MM loading as 25\/50\/100\/200\/47k ohms — prefer the manufacturer's figure. Dimensions and weight come from a retailer listing, not Manley's own page, and other retailer listings show slightly different dimensions, so verify before rack-mounting. Manley's site lists a USD MSRP of $10,899 versus the 15,500 CAD Economik listing, and Economik showed the product as currently unavailable. Manley states buffer tubes as '7044 or 5687' depending on stock, so the exact tube fitted may vary.",
