Recommend stereo amp: optical input, min 100W at 8ohms, HPF able

[adrhc]

hi, I need a recommendation for an amplifier capable of driving 2 speakers (e.g. Revel Concerta2 M16, KEF LS50 Meta, etc).

Mandatory, minimal requirements:

1. optical input (Toslink but not coaxial)
2. drive 2 speakers
3. min 100W at 8 ohms
4. min 120W at 6 ohms
5. able to work with 4 ohms speakers
6. subwoofer out (1x RCA) or line out (2x RCA)
7. allows for setting the HPF for the speakers
8. won't use a fixed LPF on the subwoofer out
9. under 1500$ (ideally under 600$)

The best candidate I found is miniDSP SHD Power (it has more than I need but is expensive), have you a better suggestion?
