Hi Gary, i've played both pieces and whilst i thought the DV was a nice enough piece, it didn't have anything particularly special about it....just felt like a good mass produced modern piece. The AMMA on the other hand blew me away....i have played the same Link for years and have never really wanted to change......until Theo sent me an AMMA . My full review wil be appearing on Theo's site soon. Genuinely, i have no need to endorse a product. i do not get anything for it. i really feel that this is the best piece i have played and allows my sound to come out to it's full potential.
