Sony R1 #10

TA-NR10
(1991 - 1997)

The last R1 / R10 component to appear, as developped by the team that crafted the other R1 units. The SS-R10 appeared even later but that was more of a one-man project launched by Keijiro Maeda and finished by others when the former sadly died.

The TA-NR10 is in fact an updated and ameliorated TA-NR1: bigger, heavier and fully MOS-FET equipped. Unfortunately, unlike the original TA-NR1 which sold very well worldwide, the NR10 were on order only, much more expensive and are now complete unobtainium.
If the R1 and R10 units gradually vanished from the catalogs throughout the mid to late 1990s, Sony kept them in fact still available in Japan on order only : dedicated service and spare parts were available as well until at least 2002 or 2003.

Do read the technical descriptions translated from a 1995 japanese catalog to understand the subtleties of these very subtle Class A reference monoblock amplifiers.
