lithojoe, the 4310 *is* the "close second best" scott tuna. :>) most tuna freaks will tell you that the 310d w/an outboard mpx decoder, or the 310e, are better sounding tunas than the 4310. (even most honest scott freaks will tell you this - the 4310 is a collectable.) most tuna freaks will also say the vintage fisher tunas like the fm90r, fm90x, etc, will *also* sound better than *any* of the scotts, tho they're not as sensitive. as will the 3000-series & above tubed sherwoods. again, the sherwoods aren't as sensitive.
so, i think it highly unlikely that a 4310 will crush everything. or even come close for that matter. i have yust sold a perfect 310d & its matching 335 mpx decoder; the decoder has been refurb'd. this combo *was* supurb, no doubt. and, its sensitivity *is* pretty amazing, for an old tube set-up. but its sonic performance, imo, is exceeded by the fisher/sherwoods mentioned above, as well as any number of other tunas i have owned or still own.
