nice system indeed. and tbh i think you did great at choosing Vitus over Dartzeel integrated. though its fancy looking, its way overpriced for what it delivers.
pity for those fans in the pics, why dont you install an air conditioning system? besides the aesthetics it will provide uniform cooling which will result in better sound. reason is that the fans will tend to cool more on the direct blowing fins and in this way they will create a thermal discrepancy between the various parts of the amps. the temperature difference between say, the output transistors on the left and right part will be definitely detrimental.
