Hackl and Vojta Reply: Our Letter  proposed the scenario of a Zeeman-driven Lifshitz quantum phase transition (QPT) to explain various thermodynamic and transport anomalies found in the heavy-fermion metal YbRh_2Si_2, in particular, their dependence on magnetic field and doping. The Comment by Shaginyan et al.  claims that (a) our results, while qualitatively correct, are quantitatively incorrect because we have ignored the temperature dependence of the quasiparticle density of states (DOS), and that (b) our conclusions and predictions are artifacts of this approximation. In the following we argue that these claims are either misleading or false.
