The sound-optimized reson hollow banana plug for the best possible 4mm plug connections. Directly gold-plated copper-beryllium contact in one piece without material transitions that impair the sound. Cryo treatment for the best sound performance and screw contact instead of soldering. Great sound improvement with the best price-performance ratio.
Enjoy listening!
