I'm the happy owner of Forrest and I did audition 3A. In fact I like them both but 3A is not great for near-field and requires much larger space than Forrest. Becides Forrest does not compromise in "size" of sound to 3A despite being quite small and deliver it much more dynamic and faster. Vandys at the same time sound more musical and worm.
I would doubt if you'd get larger upper extention than 3A or even maybe 2CE known for very high upper-end resolution upto 26kHz v.s. Forrest's 20kHz, but the bass is definitely more controlled and deep.
