Looks like your Moon 680 is 2v at 100ohm and your Progression amp is 100kohm input impedance and is also very sensitive, as it’s mated Ago Progression preamp they have for it is only 15db of gain.
You don’t need a preamp with a lot of gain, if anything I would go with either a passive pre of active with unity or very little gain
.
You can get both these and more in a Schiit Freya+, which can be used as passive, tube, or solid state. something for all seasons.

Good thing is you can send it back for a refund if you don't get off on it.
