Curious here... let’s say if I came up on a MA275. Instead of having to buy a dedicated pre-amp, would a ma6200 or ma6900 be a suitable pre-amp? I’ve heard that the 6200 was equal to the C26(!?!) preamps? Not sure about the 6900 even though it’s more beastly in power. Curious as to what light any Mac Vets out there can shine. Cheers!
