For those who are curious, here are my first impressions of the Rega Ios Phono Stage.
This unit is a Solid State, MC-only Phono Stage with adjustable gain and loading.
Loading options are 50, 100, 150, 300, & 400 Ohms.
Gain options are 64 dB or 70 dB.
DC Ohms resistance options are 6.25, 8.75, 11.25, 13.5, & 15 Ohms.
There is also a notch filter at 8.5Khz. This is variable from 0dB to -6.5dB. This is said to help
