The Manley Reference Cardioid Microphone shares the same electronic attributes as the Gold Reference Series, but has a centre- fixed cardioid-only capsule with a thicker gauge (6 micron) gold sputtered diaphragm. With the similar film thickness and construction, similar high frequency resonance (a little edge), similar proximity effect and pretty good immunity from pops and sibilance problems, the Reference Cardioid more closely recalls how many of the vintage European tube mics such as the beloved U47 sounded like when they were new. Its rich tonal balance and liquid character is consistently admired for instruments such as guitars, drum overheads, saxophone, and especially vocals. With your present mic, if you find yourself leaning on your compressors and boosting 5 or 10K to score a bit more testosterone, then the Reference Cardioid just might be the mic youre looking for. If you seem to be constantly boosting 12-18K and trying to get a clean, intimate sound, then probably the Reference Gold would be the safest bet.
