I'm trying to decide on buying a V-3, but have a couple of comparison ?'s I'd like to ask. 1) How loud is the volume compared to the SE? I have a hearing prob. an the SE is hard to hear even with my SR Pro Gold Phones. So is the V-3 louder? 2) The size of the screen? It apps. to be much larger than the SE, IS IT? (I guess old age is catching up to me, would app. all replies from those who have, or have used both-- thanks in adv. Mack)
