Hi

The only way to connect an Oppo to a G91 is by SPDIF or optical. The G91 has no multi digital or multi analogue inputs. An HD621 won't work either.

I used optical and it was fine with Trifield.

Eventually though I bought a Vanity board for the Oppo and a G61 for it's multi digital in. Very nice now and my Sooloos is way better too. The G61 has more oomph.
