My first headfi experience was SR71. It was almost three years ago.
At that time, SR71 was already a popular amp among head-fiers.
And this time I was there when SR71A came out. I am very happy about it
Real SR71 jet recon plane was rolled out early 1960. In 1976, SR71 has established the world speed record and became the fastest airplane in the world. SR-71 Blackbird - Wikipedia, the free encyclopedia
The record has not beaten until today.
SR71 is still a top notch after the long period of time. This reminds of RSA SR-71 amp.
Mine is original MOVE not a 2MOVE, anyway now I will take SR71A but this is my personal preference. SR71A is warmer and more dynamic.
But it's depends, if you like laid back music listening, MOVE will still be a good choice.
