looks like someone got to work very nice

hello, about the XT 4000D, yes there are two versions of this amp, not including the new RE XTv2. Outside is seems the same, just a litle differences at the finish. But inside it is better and also has dirk's signature and writes USA. Also I saw a difference 1,1 db louder that the old XT4000D, you may not hear it but I'm sure that in some frequences you will.. very nice amp
