This is a special, built-to-order, version of Etna for expert users with very high-gain, extra low noise phono stages, or alternatively a step-up transformer designed for phono cartridges of 2 - 3 ohms or less. Most users (and phono stages) will benefit from the regular Etna with much higher output and considerably more energy; resulting in a much better signal-to-noise ratio. If you are in doubt about which version of Etna that will work best in your system, please go with the regular Etna.
The Etna SL may provide extra pure and pristine sound from an audio system that is optimized for a low-impedance, low-output cartridge. However, this may be accompanied with a lesser level of energy and power. Lyra nevertheless has decided to offer SL models, as built-to-order at a 10% surcharge, for those who are confident that they can extract the benefits from such a low-output MC phono cartridge.
Type: Medium weight, medium compliance, low-impedance, low-output moving coil cartridge
Stylus: Lyra-designed long-footprint variable-radius line-contact nude diamond (3um x 70um profile, block dimensions 0.08 x 0.12 x 0.5mm), slot-mounted
Cantilever system: Diamond-coated solid boron rod with short one-point wire suspension, directly mounted into cartridge body via high-pressure knife-edge system
Coils: 2-layer deep, 6 N high-purity copper, chemically-purified high purity iron X-shaped former, 1.52 ohm self-impedance, 1.9μH inductance
Output voltage: 0.25 mV@5 cm/sec., zero to peak, 45 degrees (CBS test record, other test records may alter results)
Frequency range:10 Hz-50 kHzChannel separation:35 dB or better at 1 kHzCompliance:Approx. 12 X10 cm/dyne at 100 HzVertical tracking angle:20 degrees
Cartridge body: Multi-material (titanium, duralumin, bronze, stainless steel) self-clamping construction with reduced-surface higher-pressure headshell contact area, predominately non-parallel shaping, phase-interference resonance-controlling mechanisms, body threaded for mounting screws
Cartridge mounting screws: 2.6 mm 0.45 pitch JIS standard
Distance from mounting holes to stylus tip:9.52mm Cartridge weight (without stylus cover):9.2g Recommended tracking force:1.65 ~ 1.78g (1.72g recommended)
Recommended load directly into MC phono input:Determine by listening,
Recommended load via step-up transformer:Use a step-up transformer designed for 2 - 3 ohms cartridge impedance. The transformer output must be connected to standard 47kohm MM-level RIAA input, preferably via short, low-capacitance cable
Recommended tonearms: High-quality pivoted or linear tangential tonearms with rigid bearing(s), adjustable anti-skating force, preferably VTA
