I think that is a great idea of getting the W-5 and the 5.3 pre. They do sound great together.Make sure you get the 190 watt W-5 with the square emblem on the front with the word moon.
The older W-5 has an oval emblem which says celeste on it and is 175 watts. There were many other improvements other than wattage on the newer 190 watt model.
