Musical Fidelity A1 integrated amplifier
After it first appeared in 1985, the A1 quickly became famous for its hot top plate. The top plate got as hot as it did because it was used as a heatsink for the output transistors, which were biased highly into class-A. The A1's hot top made tabloid headlines, but for me it was its bold, sinewy, un-transistory sound and timeless, sharply drawn styling that distinguished it from cooler running Brit-fi competitors such as Audiolab's 8000A, Creek's 4040, A&R Cambridge's A60, and NAD's 3020.
Now it's back, priced at $1779, looking and feeling cooler than before.
