Pro-Ject it 25A by Ortofon, an anniversary model, with silver voice coils.
The manufacturer included 4 screws instead of 2 nuts, so if you don't have nuts, you won't be able to listen to it this week. Unless, of course, you have a headshell that doesn't require nuts.
The headshell is heavy (Audio Technica), 10.4 grams, and yet the resonance peak is at 10 Hz, which is very good, but it shouldn't be very good, because the manufacturer states that the cartridge's compliance is 25/10 Hz, and with the effective mass of this set, about 20 g, the resonance should be at 7 Hz, but it isn't.
So, it turns out that this cartridge, for the Technics 1200GR2 turntable, requires a heavier headshell, about 3 grams heavier than the stock headshell. A small cartridge, but good for heavier tonearms – at first glance, you might mistakenly conclude that it's for lightweight tonearms. The manufacturer's data suggests it's also for lightweight tonearms, which is not true.
Measurements:
Channel imbalance, around 0.25 dB – an inaudible difference.
Harmonic distortion is low, around -20 dB.
Channel crosstalk at 1 kHz/-23 dB and 10 kHz/-20 dB is uneven between channels in the higher frequencies, but these differences are inaudible.
Frequency response up to about 6 kHz is almost linear, then there's a sudden boost of about 1/1.5 dB to 10 kHz. What happens above 12 kHz (response drop) is irrelevant, as there's little to no audible sound there. Maybe it's the silver coils that give it the kick.?
Price: $60 (New, Amazon)
