@soix Thank you very much for directing me to the Teajay review of the Balanced Pagoda that's the heart of my mental devices these days! He claims the Balanced Pagoda is magic precisely because it's balanced that way and the RCA outputs don't sound equally well. The RCA outputs of the Balanced Pagoda should be comparable to an unbalanced Pagoda. It's a great indication, thank you!
@lordmelton I've listened to the Sonnet Morpheus MK2 R2R DAC that's one of the best regarded XLR DAC's today and I think it has monster resolution but it largely misses the magic (again!) of the BurrBrown PCM1704 + buffer output tube of the MHDT Pagoda. I've just listened to the unbalanced Pagoda. You're perfectly right about good cables!
At present I'm moving towards the Balanced Pagoda thanks to Teajay's rave review...
