I’ll amplify Don’s post. The last pair of pre-production Blackbirds are most likely the cheapest ones you will ever see. Spatial Audio Labs will try to hold the line on prices, but there are a number of imported parts in the Blackbird amplifier ... the European-made Monolith transformers, various cathode-bypass capacitors, and other key parts. If the proposed tariffs materialize, that will affect the build cost not just of our amplifier, but many other audiophile components.
I’ve got my fingers crossed the proposed tariffs never appear, but if they do, nearly all audiophile components will go up in price. If you are thinking of a major capital investment, now is the time to buy.
