Good luck finding one! l got an M901 to go with my M451, from a well known auction site in June, that one hung around a bit, that would be the second Sensation l have ever seen on that auction site, if in the USA, Audiogon may be your best bet.
As regards the 30v/130w PSU, l really like mine, a nice smooth 3D sound which is musical for not much money, l think it is a good PSU. l have not heard the Dodd, many people on this Circle have and seem to like it.
