@mjjw I had the Mola Mola in the same system with the Playback Designs MPD6, Linn Selekt w/ Katalyst DAC and Rockna Wavedream Signature XLR. It was the word of those four. The Linn is less expensive, The MPD 6 is more expensive and they sandwiched it when it was $13k. I think the Mola Mola price went up.
The Mola Mola is very good but it is not quite the giant killer everyone wishes it would be. It is competitive at is price of $13k.
I have not heard more expensive DACs from Mola Mola and comparing it to DA2I is not really fair as it is almost 3x the price. It should be better in every way.
