Perhaps I might be of some assistance here … Genus is the 25w integrated amplifier within the Prestige range which on inception and for some years utilised one 813 DHT valve per channel in the output stage , the current production Genus is in essence the same integrated design now utilising an Elrog 845 DHT per channel , the mono block amplifiers in the Prestige range are the Concero 25 W which again on inception and production utilised an 814 valve as the driver for an 813 output stage valve , the current production Concero 25 as per the integrated now utilises an Elrog 845 in the output stage in place of the previous 813.The various versions of the Genus are nevertheless a bit confusing : 813 / 845, integrated / power amp only
There is no pre-amp input functionality built into the Integrated Genus , however one does acquire an excellent integrated Headamp out with this type.
