Pictures of the amp over there, 4 X 300b and a very large internal heatsink.
who knows what the fuck is in there, transformers, current sources, given the lack of quality on the previous hifiman solid state amp, an overpriced piece of crap for sure.
for the longest time I thought that a all dht fully direct coupled amp with an $18k parts cost was so out of line that no one would ever build it. Now we have 2 companies trying to sell $40k+ amp and headphone systems.
stupidass
