Yggdrasil analog 1 (original) vs analog 2 upgrade.

I am one of the unfortunates that purchased a Schiit Yggdrasil dac just a month or two prior to their release of the Analog 2 upgrade. Mine did come with the Gen 5 USB, and I am thankful for that. But at $550 plus shipping costs I wonder if the analog 2 is worth it? I am very pleased with the sound I get now, but you all know how hard "the bug" can bite. I would much appreciate anybody with listening experience to both versions of this dac to chime in with your thoughts. Thanks.
