                                    Chandra observations of two quiecent black-hole x-ray nova (BHXN),
A0620-00 and GS2000+25 emphasize the reality of the difference in the
x-ray luminosity swings of these systems and their neutron-star
containing analogs. For A0620-00, the slope of the x-ray spectrum is
much more accurately determined than had previously been possible, and
is subtantially harder than the best fit values found with ROSAT. A 20ks
Chandra observation of GS2000+25 establishes an upper limit to its x-ray
luminosity which is nearly equal to the quiescent luminosity of
A0620-00. This work suported by NASA via CXC Contract xxxxx.
