DaySequerra FM Reference Signature Modification: $3200 (+ cost of tuner) ★
David Day's Signature Mod effectively addresses this ultimate FM tuner's cathode-ray tube's tendency to burn out. Switching circuitry has been added to allow the CRT to turn off when not needed. The Signature Mod also replaces the tuner's incandescent bulbs with longer-lasting LEDs, and uses hand-matched, low-group-delay filters for lower distortion and better channel separation. LG noted punchy, quick bass response, a deeper soundstage, and a more transparent midrange. "The new CRT's greater range of brightness and longer life expectancy makes the Signature Modification essential for owners of the DaySequerra FM tuner." The FMR25 upgrade replaces older models' cathode-ray tube display circuitry with a much brighter and more reliable thin-film-transistor liquid-crystal display, and adds a post-FM demodulation filter to remove noise at 99kHz and above. "A run-don't-walk upgrade for owners of FM References," decided LG. Price is for upgrade only; does not include cost of tuner. (Vol.12 No.6, Vol.14 No.12, Vol.21 No.6, FM Reference; Vol.29 No.9, Signature Modification; Vol.36 No.11 25th Anniversary Edition WWW) D Magnum Dynalab 205 Signal Sleuth FM Booster: $499 ★
We've left this on the list forever, because there's not much for FM fans these days, and because this unusual, niche product has shown amazing staying power. This is not your typical powered antenna amplifier. It's a notch filter that precedes the tuner with 18dB/octave edges, so it amplifies only the signal you want—sort of a pre-tuner tuner with selective gain. You can use it to attenuate signals that are too strong, and if you want to hear stations that are easy to receive, there's a pass-through. Best with old-fashioned analog radio signals.
