Steve, currently, and in order of buying, i have an MF X ray v3, and the A3.2,and there seem to be dividing opinions on which is (supposedly) superior.
Most of the bods on hifi choice, and hifi wigwam are of the opinion that the newer x ray is the better machine,this is, according to the tech geezer at MF strange, as the x ray v3 is basically the A3.2 in a smaller box, albeit with a different transport mechanism.
Having read the different reviews on the A3.5 ,the succesor to the 3.2, and the A5, they claim the lesser priced one achieves a fairly high percentage in terms of performance,compared to the higher priced A5, but, can you actually hear the difference, cos im damned if i can detect one between my 2 units!Theoretically, the A5 should be better than the 3.2, but only your ears will assure you of that.
