  Heavy-ion collisions are well described by a dynamical evolution with a long
hydrodynamical phase. In this phase the properties of the strongly coupled
quark-gluon plasma are reflected in the equation of state (EoS) and the
transport coefficients, most prominently by the shear and bulk viscosity over
entropy density ratios $\eta$/s(T) and $\zeta$/s(T), respectively. While the
EoS is by now known to a high accuracy, the transport coefficients and in
particular their temperature and density dependence are not well known from
first-principle computations yet, as well as the possible influence they can
have once used in hydrodynamical simulations. In this work, the most recent
QCD-based parameters are provided as input to the MUSIC framework. A ratio
$\eta$/s(T) computed with a QCD based approach is used for the first time
\cite{Haas:2013hpa,Christiansen:2014ypa}. The IP-Glasma model is used to
describe the initial energy density distribution, and UrQMD for the dilute
hadronic phase. Simulations are performed for Pb--Pb collisions at
$\sqrt{s_{\rm NN}}$ = 2.76 TeV, for different centrality intervals. The
resulting kinematic distributions of the particles produced in the collisions
are compared to data from the LHC, for several experimental observables. The
high precision of the experimental results and the broad variety of observables
considered allow to critically verify the quality of the description based on
first-principle input to the hydrodynamic evolution.
