Soon afterwards Anthony Michaelson released the MF A1, I suspect as a response to the obvious appetite that existed for this type of product.
In the early 80's the £250 amp market was hotly contested between the likes of Audiolab, the Naim Nait, Myst TMA3 & various Creek & Arcam designs.
With the benefit of hindsight and having owned/heard most of the others I'd say the Pm4 was the best of the bunch, provided you had sufficiently sensitive speakers to do it justice. I still enjoy mine very much on those occasions I pull it out and use it.
