Nyev we are Innuous dealers and were until recently Aurender dealers so we are in total agreement with the wonders of the Innuous products.
A couple of good points however were made by a few other posters:
1: The dac board of the Gryphon is a $5k ish upgrade. for less money you could get a Lumin T2 which is a remarkable $4,500.00 streamer however a good set of cables would add $1-3k so that would have to also be considered, then their is the flagship X1 which is a $14k streaming/dac which would easily match the quality of the Diablo.
The issue is how good do you want your digital to be and at what price?
The Gryphon digital option should be auditioned vs some of the other really good options for similar money.
So you could go with Gryphon Digital board + Innuous Zenith $9k or so
(advantage no interconnect and you get a great Roon sever)
Possible issue is how good is the Dac board, Ess 9018 is the older chip vs newer ESS 9028 and 9038 pro chip sets
Lumin T2 Plus cable $4,500.00-$7,500.00 you can stream Tidal, Qubouz, you wouldn't get a Roon sever
Advantage easy to upgrade separate streaming dac, newer double Dac 9028 pro chip set, probably better sound then digital board
:Lumin X1 insane reference level streaming dac which matchs or betters most of the $25-30k plus digital front ends
for $14k plus interconnect.
Just food for thought
