Cyrus Mono X 300 Signature (pair, DISCONTINUED)
Monoblocks· discontinued
Relative price
typical
Among the 25 monoblockss in the catalogue, this one is typical.
A band places a component against its peers and carries no price. It is deliberately the only price indicator on this page: a second one, measured against a different set, would narrow the two together far enough to give the figure away.
What it is
Cyrus flagship monoblock pair in half-width 215mm form factor — most compact serious monoblock ever produced. Cyrus Zero Feedback proprietary topology. Designed Huntingdon UK.
I/O EXCEPTIONAL: accepts both RCA and XLR inputs (most monoblocks are XLR-only or RCA-only). RCA chain-out for daisy-chaining additional monoblocks (e.g. for 4-channel setups).
Twin BFA bi-wire connectors — proprietary; allows bi-wired speaker connection from single monoblock.
