Drive tough loads is right. I once heard a DR-3 VHC (the big brother of the DR-3) kick a Krell KSA-100 into the weeds driving a pair of Apogee Divas. That was a phenomenal experience - Liszt's "Via Crucis" turned one end of the store into a cathedral with that amp. The Aleph J will not have the low-impedance drive capability of the DR-3 by any stretch of the imagination.
One thing to keep in mind is that the electrolytic caps in the old amp may need replacing at this point.
