Aragon 4004 - Load Capacity Question

The Aragon 4004 MKII is one of those great audio bargains that is tough to beat. Currently I use one driving a 4 ohm load and it does very well. It will get quite warm (driving 4 ohms) if played at higher volumes but it has never shut down. Its model number (4004) means 400 watts per channel at 4 ohms.

One final thought here. After owning both the Aragon 4004 and 8008 I oberserved the 4004 having a better, more fuller midrange, but the 8008 had better bass.
