I may be acquiring a used pair of MBL 101e Mark 2 speakers (their latest and greatest) at a good price and I will need an amp that mates nicely to them. I can't afford MBL amps so please don't recommend them, recommend something else. The amp will be mated to an Audible Illusions Modulus 3B Tube Preamp (their newest). I do not think my heavily upgraded Odyssey Stratos Extreme +++ would be up to the task of powering a 70K loudspeaker to its full potential. I would like to keep it as low as possible, say no higher than 10k but preferably in the 5K range. I am thinking Sanders Magtech Amp.
