Very good amplifier wit compact dimensions. Sold around 1981, where it was not easy for german brands as all japanese competitors had already very good products offered before. Thus Saba had to their homeworks, and in this case: They did well. This is not an OEM product, it's 'Made in Germany'. First expecting troubles as i remember the problems from my parents Grundig System after a few years as they bought it at the same time. But no, there are only a few easy things for this nice amp: The rectifier for the safety relay fails, as always, the relay contacts may be not good anymore and sometimes problems with the main switch are reported (you need a special one, 3 pole, as the PS board is switched separately). What should be done es recapping: My amp was in original condition, and SABA mixed different capacitor suppliers , Philips, Siemens, ROE, and japanese brands. The philips caps all revealed crystallization at their pins. But these are all cheap standard parts, takes you a rainy afternoon and only a few euros. What do you get? After recapping, the SABA sounds really good. And if you look closer, it can be explained. The MI 215 has a 420W Power supply. There is one big transformer, but separate windings for left / right channel. Not 100%, but almost dual mono: Separate Caps for both channels and voltage sides, in total 18800 uF. Also separate driver boards and output stages with massive heatsinks left and right, four power transistors each side. So it is not surpirising that this amp plays very dynamic and powerful, sounds much stronger than 2x52W at 8 Ohms. One more advantage: Source selection is done by integrated circuits, no problems with old switches. Built quality is like the really good japanese products produced before with 5mm massive aluminum front and knobs, and the unit is very service friendly. It's remarkable that SABA came up with this high quality amp in the 80ies as japanese significantly dropped regarding quality due to productions costs in these years. It was quite expensive, therefore not sold very much, but you can still find some amps in Europe. Some of them are in poor condition, but if you find a MI 215 on good condition you get really high class and underrated amplifier -worth to keep.
