This is an amp that I use since 2003, I bought used on ebay to replace my Electrocompaniet ECI-temporary one that has blown ..... and the first listen I stayed on the c. .! significantly higher in all, stamps, held the bass, treble. In short it is a balanced amplifier, with a beautiful medium, a fairly well-kept grave, an acute discreet and silky, beautiful image and a lot of relief.Quand at value for money ... I think it cost 5000 nine F (750 euros) or 3 times cheaper than the CIS-1!! His faults? a speaker terminals CE prohibiting banana plugs and cable more than 2.5 mm2.Si I would do this choice? yes of course, but it gave me most want to hear the higher range models! Oh I forgot! phono section is also quite impressive!
