The ASR Basis Exclusive is our most complex Phono preamplifier and is in series equipped with the expensive MIL chip AD 843 SQ. The external power unit is based on the Battery-power unit for the ASR emitter with 400.000 uF additional filtering. In the housing of the ASR basis a buffer with a
further 700.000 uF is installed. The ASR Basis is fitted with RCA and balanced XLR inputs, it can also be fitted With an extra set of RCA and XLR’s if required. Thus the ASR Basis Exclusive has a very deep and strong bass fundament, precise dissolution of all the finest information combined with an
extremely stable sound picture.

In the October 2003 issue of the American stereophile magazine we got a very good test of the Basis exclusive.Michael Framer wrote: Rhythmic snap, among the deepest, cleanest, most dynamic bass I have heard; and midrange and high frequency transparency and clarity without etch, grain or brightness.I absolutely love the ASR Basis Exclusive.
