Preamplificator Harman Kardon AP2500, stare foarte buna.
Cel mai bun preamplificator facut de Harman Kardon, construit fara amplificatoare operationale.

This pre amplifier is one of the last series when HK really made high end audio gear. This pre amp doesn't have any opamps. It is totally build with discrete components. The philosophy was that opamps don't have a natural sound. By using only discrete circuits the result is wide bandwidth and low negative feedback, essential for the smooth clear, natural sound. It is a class A build pre amplifier with a great natural sound, wide and detailed stereo image.It represent the best in solid state preamp design. Its sound is natural, transparent with an outstanding stage. The sound stage is wide and deep and stable. I am particularly fond of its headphone amplifier when driving the Sennheiser HD-600. It spread the sound stage in front of you instead of in your head.The all discrete class A headphone amplifier is better than many dedicated one on the market today.
