I would like to thanks MR. Bhagwan for his input,i am going for this the Zdac & the ZAmp V3 is 64K after disc but waiting for the silver model from Audio Excellence infact before all this I tried to contact Audio Excellence for some details but they don't respond so I just kind of sent a query to Parasound marketing and was replied to by Richard Schram the President of Parasound asking questions about how I want to use the system.It surprised me,he said he would get on to Audio Excellence and they mailed me the same day.i started off when I was young in the 70's with a norge amp & speakers after that had a Leak Amp which was very good after that bought a Bang & olufsen Tangental Drive turntable and had to stop with all this now I am 57 yrs and this was on my bucket list so I am going for it.Thank you Gentlemen for responding.
