  1. The German Chancellor Miss Angela Merkel spoke yesterday on German TV of the greatest challenge ( COVId 19 ) that Germany must ever face after the Second World War, precisely because our indirect neighbour Italy is the most affected country in Europe. While the COVID-19 case number in countries like Germany, France and Spain increased tenfold within 8 days after reaching the 100th case, the virus spread much faster in South Korea and Italy in the first week after the 100th case. The number of confirmed cases of the lung disease COVID-19 worldwide amounts to approx. 219,000 cases by March 19. Italy was the country outside of China with more than 35,500 confirmed cases. The number of deaths worldwide rose to about 8,800 by this date.

    The AD to DA conversion is only for the purpose of removing pops and tics and nothing else.

    The audio cd recorders did that already when you burned records to CD the filters filtered the pops and ticks.Of course, this has nothing to do with the separate AD converters.But technologically this hat is over 20 years old.

    So, you're not listening to pure analog any more then correct?  It converts analog to digital, cleans it up then converts the digital back to analog.  What would the analog purist think about that?

    I can tell you that. A really good analog drive with a really good pickup does not need the AD / DA conversion process. Neither for the resolution, coarse-fine dynamics, precision, locatability, and so on . Analouge Signal > Analogue Singnal is the purest form of signal transmission.Nevertheless I find this phono AD / DA converter technology interesting. Especially for younger users who like to experiment, because they lack the reference to classical analog music reproduction.

    It could have just as easily been alcohol in his case.  Some people can't handle drugs.

  5. Phase 2: Now the old sound insulation inside the loudspeaker cabinet has been replaced by a more efficient one. This novel insulation material massively dampens air- and structure-borne sonic influences. It is only 0.3937 " thick and has been replaced in a ratio of 1:1 in terms of surface area from the older insulation material.

    Additionally I have damped the horn bodys outside with bitumen mats, to isolate them against the structure-borne sonic of the 10 " drivers

  6. I think it's time for a summary of all modifications to the RF 7 MK II. Then you don't have to dig through the whole thread to find the important details

     

    Phase 1 All contacts to the chassis were replaced by pure copper connectors. In addition, a 2 x 2 mm2 monocrystalline copper loudspeaker cable for the horns as well as the  4 x 10 " Woofer. The terminals received WBT OFC pure copper pole terminals  for the cables and the crossover connectors were replaced by pure copper connectors as well. These measures have significantly reduced all contact resistances.

    In the shyt hole city of Laredo, TX where Mexico's in-your-face "Patron System" flourishes and residents must be registered under a particular party to vote in local elections.....  the City Council voted to enact a City Wide Lock-Down that goes into effect tonight, 12:01am. There is 1 official Wuhan Virus case confirmed and then there's someone they are referring to as "Citizen X" who gave it to that 1 poor bastard.
