If you dont have to have DSD there is a new Wadia 321 on Ebay for ~$1.2, which in my opinion is a good deal as it was originally $3K. I have the same model and the only real difference between this model and the di 321 is the DSD capability but you might want to verify that. I have the regular 321 and I bought it to match up with a Rogue RP-1 and a class D amp. My 321 gets played daily and when I work from home it's cranking all day and has not missed a beat. There are a few detail reviews out there on the regular 321 but have not searched on the new di. I really like my 321 it surely helped take the edge off and extend the sweet spot for my class D amp. Also Wadia, for better or worse, is now part of the Mcintosh Group.
