Nope did not forget...I can only surf so many boards....

I read the FAQ page at AZ and it all sound good..but the bottom line is this: with MC2 RCAs I had to turn up the volume to 12 to get the same output as the Mod'd MC2 outputs it 9 o'clock. To me that save tube life and does not "overdrive" the Earmax over time...
My sound impressions are great! There is really no difference between the two sonically. It really just came down to the number of connectors.
I just spent a few weeks with the Marigo 5.1 Digital ($695) and I prefere my AZ. I am now listening to the JM75 ($100) Digital..first impression: Good Value...
RL is currently manufacturing the Mod'd MC2 it just has not been marketed to much just yet..
