Did my first preamp comp between the internal pre's and a V2. While the V2 is certainly a better preamp, the differences were not nearly as large as I was expecting and seem more like the sound of the 722 pre's than any other all in one box pre's I have heard from Edirol, Tascam, Marantz, Korg, etc. I did not compare 48V phantom as I used Stewart BPS-1's and xlr splitters to the two different preamps. Source material was played fairly loud through my meyer playback system and only needed 40 db gain from the V2 and +14 gain on the tascam with the low gain setting selected. This leads me to believe that the tascam mic pre's should handle loud shows without need for mods or fear of overloading the inputs. Nice!
Was also glad to learn the gain on each channel can be adjusted quickly on the fly without need to hit the channel solo button for 2 seconds first. Only need to do that if you want to monitor one particular channel.
Liking this thing so far. More impressions to come....
