SA-Reference Power Amp
  • Product Detail
In 1992, PLINIUS released the SA-250 Class A Amplifier. This amplifier was to become our reference standard, and one to which we compared all of our other products.

With the development of the PLINIUS Odeon, SB-300 and SA-201 it became apparent that the SA-250 had been eclipsed as our reference product. We therefore set about correcting the imbalance. While we continue to champion our asymmetric approach to circuit design we have refined the operation of our output stage with by far the largest improvement being in the high frequency performance. Along with other refinements we have managed to improve on the SA-250, and exceed the new standard set by our other products. We are proud to announce that a new PLINIUS Reference has been created.

The PLINIUS Reference Amplifier has been designed specifically to work as either a balanced monoblock, or a stereo amplifier. As a balanced monoblock the SA-Reference will exceed 1kW of pure balanced amplification.

In PLINIUS tradition, premium components have been used throughout and Class A operation is maintained to over 100 Watts per Channel while 300 Watts is available in stereo mode to direct and control the most demanding speaker systems.

The PLINIUS SA-Reference amplifier embodies all that we have learned in the past few years and while modelled on the Classic SA look it has been given some aesthetic changes to bring it into line with our present styling.

Sonically the SA-Reference paints a seamless picture from the most tuneful and accurate bass to a sweet, extended and extremely believable top end.

All PLINIUS SA-Reference Amplifiers are hand built and as each is individually engraved on the front panel, we are able to offer some customer selection of the serial number. Some numbers between 101 and 200 are still available. We will endeavour to have your specific choice engraved if that number is still available.
