Usually, Rolf maintains common following daily schedule: in the early hours, he sits in the Office, then it is available to its customers in the afternoon by telephone, in the evening listening and tuning begins.

He pays attention the RG 9 for 15 years now, he surveyed every square millimeter 100-fold, with each component he wondered again if there is not a better. In any case, the RG works 9 MK 4 2009 for 4100 euros now with a transformer, the core of which can be common multiple glow Rolf which greatly facilitates the orderly magnetic flow is. On the other hand the transformer is completely in a thick (bag expensive!) MU-metal tanks, which prevents the escape of disturbing fields.

He has not the usual output winding with Center tap, but two separate for the main. Here and there set independent precious diode groups plus and minus equal, what gives that a transformer and mains independent, clean ground connection can be selected.

Da Rolf community expects normal Electrolytic Capacitor power storage to hazardous waste, he lets a small North German company manufacture its own tuned. In the case of RG 9 and for the supply of a total of eight Toshiba output transistors plus foreman four piece with the unusual value of 13_000 of micro Farad including tolerances. And because it supports the space according to his statements, the Duisburg uses specially again two 7500er of the same manufacturer for the pre circles.

Who is voicing for an English art, look to the Symphonic touches on: is served by a “EE-TeX” line with air-similar dielectricity the bright, it must be a Teflon cable in the case before-end connection. And also leads to the speaker terminals which Finger thickening special, Rolf enters common fully  Antivibration mats and varnishes.

In the listening room, the RG 9 revealed a downright outrageous naturalness. It was March, what it wanted from the small band up to the largest Orchestra, RG 9 remained on absolute passage put the music on green, – as he did with nothing to do – (what the RG 10 managed by 12/02 still not quite as good).

So, sound colors, forms, movements were allowed to celebrate real messy. Also phono sound alive-fine MM and MC. There have been discussions just because of altitude. Not that the RG 9 of the percussion took anything away, he gave way but dangers discreetly back. Many want to have exactly that, that’s why the RG has earned 9 MK 4 2009 proud 56 points and a highlight .
