Mike: The Etna's recommended tracking force is 1.68 to 1.78g (1.72 g recommended). The 9.2 gm weight of the cartridge, its compliance of 12×10 cm/dyne , and 11 gm effective mass of the Triplanar VII make them perfectly matched so far as I can tell by listening.
The tonal color and balance of this cartridge is phenomenal. It is not overtly analytical. It's very immediate and very lively, but the images are fleshed out with sustain and body too, so it's not thin sounding. It's a big sound and can be exciting; not at all polite or delicate. Frequency extremes and sound stage space are still developing with break-in so it's hard to tell where they'll end up. Bass and treble are there, but don't call much attention to themselves. Extreme highs aren't yet airy and lowest bass notes aren't yet bottomless and lack some impact. It is still a little tight and hasn't opened up much. Early on it could be just a little HiFi sounding at times. There's been a very slight hardness, but only on a few occasions, but that seems to be gradually being replaced by a touch of sweetness. Most of the reviews say something like it's a cartridge for all types of music and I can believe that based on what I've heard so far.
