Build quality clearly favored the Minimax.
I never really heard either the Xindak or the Minimax with the stock tubes.
Sound wise, I felt that the Minimax and Xindak (with the best tubes inside) were very close, maybe the Minimax had a tad more detail and the Xindak a tad more soundstage, but I didn't have them both at the same time. I like the NAD 541i quite a bit and for the money (paid $300 new with warranty) was a no brainer at the time. Just found that the NAD had a slight tendancy to sound a little harsh on certain recordings (e.g., saxophone or distorted electric guitar).
Another thing to clearly check out is the repair network out there. The Xindak does not have a US distributor right now (per Bertram Audio). The gray market Chinese ones through www.nysound.com or ebay may be tough to service, time will tell. With the Minimax I felt that Bill O'Connell was a trustworthy gentlemen and that if worse came to pass, PartsConnexion could service it too.
