here's one:
one
think it has as much to do with supply in US and price as with any negative feeling
I'm a big fan of when ever possible of tracking w/o 'color' (on other hand am also big fan of Telefunken V72/76s and modified Altec 1567's which not only have unique 'character' but 'color') the API 3124 remains one of my all time favorite work horse pre's (and at this time probably would run you about $600/channel in the US)
The DAV BG 1, which from your quote has apparently inched up in price remains, after the API another favored tool . . . it has similar quality to API but probably not quite as 'straight wire + gain' transparency
Use both but never compared BG1 head to head with Mico but my experience with Mico suggests that for what it is, if the choice was between the two I'd probably be swayed by price while probably subjectively prejudiced towards API I don't find Mico to be as transparent and while I found that I used the Mico's digital outs only rarely they can be useful
a bit less sanguine about the phase alignment switch .. . not overtly critical it's just one of those 'what the hell' kind of things
Have nothing against the Grace m101, no specific idea why I have no particular affection for it (other then can't love all gear all the time and still get any work done) but I am very happy, from a long term investment standpoint with DAV build quality . . . Have less history with Mico and have yet to run a truck over it but have no specific complaints Unfortunately there are at least two versions with the 2nd having slightly better gain linearity . . . if you are primarily tracking one source at a time not too much of an issue, but as they supposedly brought the revision more in line with console pre's it would be nice to know which version you were getting for the money
over all it probably doesn't help that I'd be hard pressed if I had to choose only one among 3 of your top choices P-solo, DAV BG1, and Audient Mico . . .
