Faithfully rises to any load challenge. Drives the amp-killer CS5i, Apogee Scintilla, Infinity RS & Kappa to high volumes no problem. Never stumbled in 27 years of such duty.

Somewhat dark sounding via XLR yet tonally rich, open, detailed and musical in SE mode with exceptional dynamics, soundstaging and depth. Lifetime Warranty. Ultimate reliability.
