A lot of good suggestions. what comes to mind is the Lampizator TRP it uses tubes in a DHP (pentode) fashion. audition it first. Let us know if you decide upon this DAC.
Seeking to upgrade from Weiss Dac 204
Looking for suggestions to upgrade from Weiss Dac 204 which I use with a Modwright Linear power supply. /the sound is enjoyable, but I am seeking a richer and fuller sound. Any suggestions would be appreciated. My budget is $7500.00 new only. Thank you.
