Wow, was considering buying a pulse. After reading the last few pages, even if the product is excellent (Which doesn't seem to be the case) this company is awful. Is there any redeeming feature to all this?
I wouldn't unless you're getting it at a really really good price.
There are so many other options from more reliable companies that sound as good or better. I'd go for any of the Schiit products... or the Emotiva DC-1. Or anything that isn't going to have USB connectivity issues... or volume controls not working... or sync issues.
