CX-2 is even cheaper than Cx-1 , has remote capability , and loudness control. I bought one at sound sales man discount 50% of list price. I was told by Yamaha Tech dept to buy Cx-2 instead of Cx-1 as many Cx-1 had cold solder issues . It works so well with my Acurus A-250, Before I bought it I used the pre-amp section of my Yamaha 1020 receiver . Day and night difference when Cx-2 was used, Sound Stage was dramatic with the Cx-2 instead of pre-amp section of Yammy receiver !!
