The store where I bought the Xindak is doing a diagnosis at no charge on the PS Audio. I will likely trade it in to them after they find out what's wrong & make me an offer.
After spending more time with the Xindak, I am stunned at how good it is for the price. It's biggest strength (partnered with the Adcom that I'm not fond of) is midrange in general, & the especially vocals. I have NEVER heard vocals on cd sound this analog like. I THINK the weaknesses I'm hearing are more the Adcom then the Xindak, I'm not going to mention them at all until i get my NAD Amp back.
At least partnered with the Adcom, the Xindak is WAY better then the PS Audio. I can't remember the last time I listened to digital without feeling the need to read a book or fidget. With the Xindak, I just sit with my eyes closed & listen, especially to rock with well recorded vocals. It's also reminding me why I used to care so much about high end audio.
