The Music Room often has used yggies. Buy one, listen for yourself and return it if it doesn't please you. Note that you will have to pay shipping and a restock fee. Perhaps you could borrow one?
Is this a meaningful upgrade?
I currently use a Schiit BitFrost 2/64 DAC. I'm considering an upgrade. I don't have any specific complaints about it. I think it's easily the best in it's price range, like most Schiit products.
I'm considering buying a used Schiit Yggy as an upgrade in overall quality rather than a change in sound. It uses the same DAC chips but with higher quality implementation.
Is this a meaningful upgrade or just a sideways move?
