  Recent studies (J. Alloys Compd. 695 (2017) 2661) of the electronic structure
and properties of $(TiZrNbCu)_{1-x}$$Ni_{x}$ (x$\leq$0.25) amorphous high
entropy alloys (a-HEA) have been extended to x=0.5 in order to compare
behaviours of a-HEA and conventional Ni-base metallic glasses (MG). The
amorphous state of all samples was verified by thermal analysis and X-ray
diffraction (XRD). XRD indicated a probable change in local atomic
arrangements, i.e. short-range-order (SRO) for x$\geq$0.35. Simultaneously,
thermal parameters, such as the first crystallization temperature $T_{x}$ and
the liquidus temperature showed a tendency to saturate for x$\geq$0.35 . The
same tendency also appeared in the magnetic susceptibility $\chi_{exp}$ and the
linear term in the low temperature specific heat {\gamma}. The Debye
temperatures and Youngs moduli also tend to saturate for x$\geq$0.35. These
unusual changes in SRO and all properties within the amorphous phase seem
correlated with the change of valence electron number (VEC) on increasing x.
