Fremer in that AnalogPlanet review above mis-typed some of the spec info for the Delos, particularly the loading range. Here are the specs directly from the Lyra website:

Specifications for LYRA DELOS:
.....................................................................................................................
-----------------------------------------------------------------------------------
I'm no expert here and only just recently upgraded my phono preamp to one that allows a wider range of loading options for my Lyras. I loved what I was hearing before, but love what I hear now far more. Loading really has a lot of impact on the sound as does VTA. The rest are important -- getting the VTF right, for example -- but I've found loading and VTA have the most effect on how the carts sound.

- Output voltage: 0.6mV@5cm/sec., zero to peak, 45 degrees (CBS test record, other test records may alter results)
- Frequency range: 10Hz ~ 50kHz
- Channel separation: 30dB or better at 1kHz
- Compliance: Approx. 12 x 10-6cm/dyne at 100Hz
