NEW KR AUDIO RK LIMITED SERIES TUBES


The Riccardo Kron series of tubes was born as a collaboration between best300b.com, the international e-Shop specialized in DHT triode distribution, Lampizator - a Polish amplifier factory being one of the heaviest users of DHT tubes in the world and KR Audio manufacturing plant. The plans were lied out to build bespoke, reference grade tubes that would reshape the industry as we know it, honoring at the same time the legacy of Riccardo Kron construction principles and sound taste. Engineers at KR Audio proposed a number of changes to the current tube lineup and these modifications were critically evaluated by Lampizator, in the process of the creation of the Reference DAC DHT tube unit called The Pacific. After the audiophile seal of approval - Riccardo Kron series was born.
