Description
As in the meantime my Mr.Nixie Superb Phono has become established as an insider's tip in audiophile community, they called for some additional features, like an easy adjustment of the matching impedance and capacitance to the cartridge. At the same time even higher demands on acoustical performances were formulated, which results in the development of an independent sonic reference.
After several months of extensive R&D time such an audio reference has been created, which needs not to shy the comparison with the best and most expensive phono preamplifiers of the commercial market.
As the idea for the development was being made in the audiophile DIY community, it was only appropriate to offer a new phono preamplifier as a kit version which gives the experienced DIY now a portal to the unknown acoustical reference technology. As a reminiscence for the developmental efforts this new DIY phono preamplifier bears the beautiful name DIGNA.
The price-performance ratio of the DIGNA can be described only as "galactically" after various listening tests against established high 4-digit priced high-end top dogs and is absolute unique on the market.
Only the best available audiophile components have been choosen for DIGNA, creating a DIY standard that is not available on the world market in this high end quality.
Another special feature is that thanks to its 3-PCB concept, the DIGNA runs absolutely hum-free even without any enclosure. This opens up a completely new ways for "case-modders" as they can now create their own housing. Appropriate mounting holes are available on the PCBs.
