Reviewed Nov 10th, 2015 by C.A. Ray

I have recently purchased (2015) a complete 'Urushi' system to include an M-73. I can, without hesitation, advise it is a well finished and exemplary performing amplifier.
Because I listen to 'music' at the approximate level as the original recording, this unit easily reproduces excellent clean clear sound effortlessly through my B&W 802 Diamond speakers.
Remember these components were produced in a totally different era, performance agenda and manufacturing mentality and plan to have many many years of enjoyment (it should see me out). It was not overly expensive, but I would have had to pay a considerable amount more only to achieve marginally greater performance.
Why do I say that you say, because I was in the final stages of considering the purchase of an esoteric system that was going to cost me just under £100K. This Pioneer Urushi Reference system was via an estate probate.
I might consider an M-93 in the future but the M-73 is, as I've said, sufficiently adequate.
