This i can tell you not all LPS are Equal the best under $1k and I have compared them all in our audio group Linear Tube Audio ,it not onky weighs 6 pounds
but after looking under the cover nothing under $1000 is on par ,we have been comparing Anyone wanting solid advise ,email me I can give you a break down
The Chinese ones at small green computer are perfect for the modem,router combo ,and coming out of the dirty end ,Thst being said on the end point you absolutely want the best LPS as well as decent power cord ,and DC cable
Linear tube Audio ,even the DC cable is = to what others charge $100 for I have on my sonore deluxe it sounds great but needs a solid 100 hours runin.
