Looking at the Aurender:

4 completely independent power supplies, each with its own transformer. One for digital transport, one for each of the analog output stages and one for digital/dac. Looks like a fully balanced/differential configuration. I can totally see where the Classe bypassed would work better because the Classe doesn’t have as much into its audio stages. Classe is a very good HT processor, but like all processors, shared power supply for 8 analog channels. Shared transformer for everything. Switched power supply for digital.
I highly doubt that the Lyngdorf will do better than either the Classe or the Aurender, since it now has 16 analog channels to deal with (twice as many as the Classe). Unless your just looking for a higher end HT processor that will support all the new standards and 4K. Also, the Lyngdorf has no analog inputs.
