The linear stability analysis of a planar detonation wave is reformulated for an arbitrary
caloric equation of state in an attempt to better represent the stability properties of
detonations in condensed phase explosives. In this paper, we focus our attention on a
Tait equation of state which allows us to prescribe a finite detonation Mach number, and
simultaneously allows for a detonation shock pressure that is substantially larger than the
ambient pressure. We show that the effect of increasing the ambient sound speed in the
material, for a given detonation speed, has a stabilizing effect on the detonation. We also
show that the slow reaction stage that is present in detonations in explosives like liquid
