I have owned vac renaissance 70/70,s for over 4 years,it is a solid reliable great sounding piece of equipment,currently driving quad 989,s to good effect.A friend bought some class a/b more powerfull mono blocks and suffered a few minor glitches.Kevin Hayes handling of the situation marks him as a gentleman and person to be trusted.Great product designed and built by an honorable company,pick the correct model for the job and relax.
