Thank you for your purchase of the CF-080LS Hybrid Line Stage Preamplifier. This amplifier represents the fruits of
over 30 years’ design experience by Masataka Tsuda, during which he has continuously pursued the limits of circuit
simplification and optimization in order to attain the purest music signal possible.
The CF-080LS represents the pinnacle of our thinking in amplifier design. It is so advanced that we literally could
not have designed it two years ago!
