Signature Edition by Robert Zeff is our no compromise, high power, audiophile amplifier designed and engineered by Robert Zeff and the staff at Nikola Engineering. This design is taken from Robert's many years of experience in both professional and the car audio industries where he used, repaired and built high power, high fidelity amplifiers almost every day. With these lessons well learned over 30 year, he finally had the opportunity to make for ARC Audio the no compromise, no limits amplifier he had always dreamt of.
