Well, the Harbeth’s run the signal through about 30 POS network components, so long term, they have a ceiling. You’ll never be able to upgrade the network without running it as external. Just not enough room to make a double-sided PCB network rack in there inside the speaker. The super cheap, bottom of the barrel, components are smaller than those that are considered to be audiophile quality. Some would say this is not a problem because the speakers produce a pleasing sound. However, these types of network components have an absolutely undeniable negative affect on the signal. The drivers, in the right hands, have much more potential than they will ever show here as configured by the engineers at Harbeth. But don’t shoot the messenger. Much more well known and respected network engineers have said much worse about what’s behind door numbers 1 and 2 on the Harbeth Show. Of course you remember Let’s Make a Deal?
