For more air, you may try Tesla E88CC Gold Pin. This was my choice with Tubadour IV, but I am kind of partial to old Tesla tubes.
Tube DAC with i2s input?
Hi all, I want to upgrade from my Pontus II which is a good DAC but I'm looking for better depth/dimension, separation and analog warmth. I recently added a Laiv uDDC to the Pontus and that improved things notably so I'd like to keep that option for a new tube DAC, however most I come across do not have i2s input. Any suggestions? Budget $4-6k thanks. - Rich
