Ronin, thanks so much. Yes, I think I'll start with the ES-9 and slowly figure out things from there. This will also save my wallet as I expand the rack. Thanks for the input on the Voltage Block and the attenuators/mixers. I was hoping the hex VCA and Maths would be enough, but I'll look into dropping the Block and adding some more attenuverters and mixers, maybe still have room for Mimetic Digitalis too. I promise if I ever hit the lottery, I'll make sure you find that 'evaluation' 4MS SMR. Cheers.
