Sonnet Morpheus Owners! Preamp or Not?

Yes, thank you.  I'm in agreement on the Hermes/Morpheus being such a pleasure to listen to music through, and I too see no obvious upgrade path. In fact, I worry any change would be a change I wouldn't like - I'm super happy with this setup.

I like to have the precise volume and balance control, switching, etc of a preamp but don't want to sacrifice the quality of Morpheus in any way. If there was a bump upwards in sound with a preamp that would be a real plus.  I understand that while varying the voltage to the DAC boards is a clever volume option with little or no downside, wouldn't an optimum fixed voltage be best?

Thank you all for sharing your experiences please keep them coming.

Understood but there are features of the preamp the Morpheus doesn’t have and the voltage regulation to the DAC boards spec best when output is full and fixed. Not sure if this matters when listening or not.

The LA4 is quite transparent as are the AHB2’s so coloration should not be an issue. Thanks for the feedback folks and looking for more experiences from members.

Thanks, and then this preamp discussion should apply equally to the Pasithea as well as the Morpheus.
