Seller Unresponsive after payment.

As @mbarrett635 ​​​​​​shared I would have a little more patience, with him being out of the country he's probably experiencing inevitable delays getting anything done. You have up to 6 months for a PayPal claim and the absence of a tracking number proves you did not receive it. If you are too worried then initiate a dispute to get the refund process started.

He has a fairly extensive posting history here and reading some of that might alleviate or increase some anxiety once you get a feel of who he is.

Good luck!

Being out your money and the item you purchased is not a good feeling.  I recently went through a similar experience but in my case the item purchased was defective.  It doesn’t hurt to file a claim.  It can always be canceled. You’re certainly justified in doing so.  Same for negative feedback.  Hopefully everything works out for you.  Once it does you’ll have a different perspective on things so sometimes a little patience can be a virtue   

After a month of wait, seller shipped it last friday and refunded me 50% off the price so it becomes a $300 Dac. I haven’t tried and setup it yet still waiting for my cables to arrive tomorrow. Will get back tomorrow if it works and how it sounds.

Can’t even begin to imagine why a DAC would need two big-ass KT 150’s…
