I have the same model. Whats nice is the repeater function. Most amps you have to buy seperate cables per phone which is costly plus splitters gets spendy. You also loose by splitting the signal up thats if you use two phones.
But you dont worry about all that with the DA4000MR-10A it's wireless. Connecting is alot quicker. I know will my sprint pcs phone hooking up to the internet its alot quicker and smoother. Usely my sprint phone locks up and diconnects. Not with the amp havent had any problems
Overall buy it. By a chance you buying from.
