I am still enjoying my VA100 Evo, which I have had for nearly 20 years, in my opinion it sounds and looks great. Mine is has the polished chrome fascia with the matching CD player below.
As well as the usual checks with old amps (noisy volume pots, etc.) I recommend you listen carefully to the Aura at zero volume to check for any audible hum from the speakers. Some Aura's (and other amps) are susceptible to this and the noise level varies, but you must listen to make up your own mind regarding the level and its acceptability to you.
