About the QC Twenty Four
The Quad QC Twenty Four is a line-level valve preamplifier that employs a radically simple audio circuit with relay input switching to maintain signal purity, embodying Peter Walker's philosophy of a 'straight wire with gain'. It uses a new old-stock 6111WA double triode valve, hard-wired for reliability, and features transformers designed by leading authorities. Connectivity includes 5 line-level inputs (CD, Tuner, Aux 1, Aux 2), 2 buffered tape loops, 2 main outputs, and an optional phono port or module for MM/MC cartridges. Matching the classic Quad aesthetic, it pairs ideally with Quad II Forty or II Eighty power amplifiers, delivering a smooth, full-bodied, cohesive sound without tone controls or remote. Production spanned approximately 2004-2008, and while still available new from some retailers, it is considered a classic model no longer in active manufacturing.
