The RD-100 is the latest addition to our Reference Seriesof products. This DAC however is not your ordinary DAC. Itfeatures true analog inputs and a volume control. The RD-100 also uses the typical modular topology that is beingused in our other products. This modular topology offers a future proof product, thatcan always be upgraded to our latest technology. Pushingthe envelope of achievable sound quality. When we designed the RD-100 we took advantage of thesuccess of the SCD-010 technology. We optimized everyaspect of its design to be able to fit it into the smallerchassis, and match the lower price range of the ReferenceSeries. Still pushing the performance to the next level,above the SCD-010.( The SCD-010 has been replaced by the SCD-025 inaugust 2012 ). As something new – we have included two analog inputs– one single ended and one balanced. These analoginputs are kept in the analog domain and not convertedto the digital domain, as with some other similarproducts. When the analog inputs are selected – the fulldigital part of the DAC is shut down so no digital noise ispicked up by the delicate analog signals. We have implemented an new version of our relay basedvolume control, to complete the analog part of the RD-100. This makes the RD-100 a perfect analog line stageon top of its digital functions. The analog volume controlis also functional when the digital inputs are used. Thevolume control in the RD-100 can be bypassed when theRD-100 is combined with an external line stage like theRL-101.’
