I've owned the M1+ since July but have only used it with a pair of Nola KO's and (2) Rythmik F12G's. Great integrated amp in my opinion especially considering the build quality and the price. In the past I have used the EX-M1 with Reynaud Abscisse Jubilee's that also have a "ribbon" style tweeter with excellent results. The Kinki amps are pretty neutral.
