Cyrus Two

1 9 8 7 1987
1 9 9 0 1990

Start of the understated but boosted european designs.

Or how we managed to take the high-end market back from the japanese by offering less and, thus, more.

A bit like the 1970s Volkswagen slogan :
"small is big".

Non-magnetic diecast aluminium base, beefy toroid supply and caps, short signal paths and, let's face it, somewhat boring shoebox looks.

This assumed starkness, however, vanishes when playing music and with the optional PSX external power-supply... However, this is to be teamed carefully.
