For sale is my highly regarded Plinius SA 250 MK2 in silver. This is an original MK II unit, it operates in fully balanced Class A . l would rate its condition as a very conservative 8, l cannot find any cosmetic blemishes on the amp at all (see pics below)
l purchased the amp off the original owner in New Zealand Feb 2005. Before shipping it to Australia l sent it to Plinius in Palmerston North where the amp was heat soaked, bias checked and went through all the QC checks a new unit would prior to shipping. It was given a clean bill of health, l was adivised the amp had seen little work and was in as new condition. Receipts for the amp service are included with the sale.
Rated at 250 Watts/ch into 8 ohms, 500 watts/ch into 4 ohms and bridgeable to 1000w monoblock operation. Switchable from class AB to full class A via the front panel. Comes with the original massive double box, manual, warranty card and invoice.
This amp drove my now sold Equinox Jupiter's with their sub 2ohm load with ease and sounds wonderful. Musically nuetral, it has a touch of warmth/tube like liquidity and posses none of the harshness and brightness normally associated with SS amplifiers. Retail on these l believe was originally around A$14k, the current model retails for closer to A$18k. The SA-250 is a real reference solid state amp
l am asking US$3300.00 ono for the amp, this is a bargain when compared to other recent sales. The amplifier is located in Australia but l will assist with overseas shipping. Any questions don't hesitate to drop me a PM or email on xygtho3@gmail.com
Cheers Mondie

Here's some further info from the Plinius website:
PLINIUS technology includes fully balanced, class A operation for all products; this reduces many kinds and sources of distortion. The balanced circuitry inherently cancels out even order distortions, and the class A operation eliminates small signal nonlinearities and crossover distortions. A switch allows the user to select class AB operation; this produces less heat for noncritical listening (dance parties), and allows you to hear for yourself and appreciate the sonic benefits of class A operation, contrasted with the class AB operation mode that many other power amps (both solid state and push pull tube) employ. It also provides a convenient way of leaving the power amp on, and warmed up for optimal fidelity, at all times, but with reduced power consumption compared to the class A mode.
