LA90 measures amazing but I have a few doubts about its thermal design and some other comments:
1) How functional are the two heat-sinks? They look very badly designed with horizontal fins and very small gap between them. How much air is actually circulating through those gaps?
2) If you put those two amps next to one another, in bridged mode, with preamp/DAC on top of them, like in a pictures, you will get even worse cooling
3) Such a small box for an AB class amp??? Why? It looks they cared more about the design than performance.
4) What is the point of special connectors on the back?... so I have to buy their custom cables???
5) For a company that praises itself for its superior technological prowess, cleanest sound, ultra low THD+N ("lowest noise of existing power amplifiers") etc, stating the power at 10% THD+N is kind of funny?
