Brandon (Owner of Mohog) is married to my second daughter, as a "get closer to my son-in-law" we built a set of mnats versions almost 4 years ago (He was running a studio in San Diego using Sonar)...anyway he took the ball and ran with it, has done a ton of research (he pretty much builds the "F" version only) and is constantly improving every aspect of his product.
You would be amazed at who is using his stuff now, MAJOR Grammy Producers swear by his stuff...AND he's a huge Cakewalk supporter...
I have a couple of units and am building a third...we had 2 of the UA 1176's in the studio there and did some A/B comparisons...the noise floor difference alone sold me, but having the extra transformer inside (Its based on a Neve style so you get some British kind of color if you want)...
I'm trying to convince him to reset up a mixing studio there because he's really talented at that as well...currently he has several other boutique gear builders asking to trade for his stuff...
So yeah I'm a little baised (but I was involved on the initial development/I build mostly tube stuff now)...
His prices are more than fair considering each unit is hand built, tested by him and guaranteed...(they are also hand numbered)...
And on the EI thing...I'm going back on it today...I never did get it to work, so I'm going to try the 32 bit version of X2 and see if that makes a difference...
By the way, my UAD stuff seems to be working in X2/Win7/64 but I ma on 6.0.??? with them...
