Used more than 10 years, the most comprehensive ever prampli imagin.Des gniaux filtering, all type of rglages sensibilitcharges etc. A great prampli between the micro tuner! ! The must MODEL din and a cinch to CD collector module with module and coil mobile.A the costs a little worse than his little ERRF the 304 much easier and Diapason d'Or. No headphone jack . Not too expensive in time, but the rating goes up, a good choice for a driver amplifier of the brand.
