Hi
As per specs and what I know....both models are same components barring the extra output....
Please check for the subwoofer Out port ...should you want to add one later......I somehow could not see the same in the rear pics posted on their website....
I reverted on your post for Good Bookshelf speakers....typically PSB speakers pair well with NAD.......PSB also has good decent subs....SUB125....check first all frequencies which the bookshelf speakers can deliver and then only decide if you need a sub....remember ...no point going for a sub if the difference is 5hz more than your bookshelf speakers....
Since you are based in Mumbai, there are many dealers......Marantz amps are good....pair well with Jamos, Missions, B&Ws, Polks etc....
