The QC-twentyfour is a preamp with multiple source selector that represents one of the ultimate pieces of audiophile-grade gear one could add to his/her sound system for extreme ease of operation and without fear of altering the sonic signal.



The QC-twentyfour is yet another pre-amp, a device that will work in perfect compliance with the other exquisite preamp, the QC-24 phono stage. The purists claim that only the valve-based gear can get as close as possible to the original sound recording and that solid state circuitry must be kept at an as minimal as possible level in order to preserve the sonic source as pure as possible.



The QC-twentyfour preamp sports no less than 5 line-level inputs and an additional phono insert and runs on a single 6111 twin triode with internal signal switching relay; the fast recovery power supply rectification ensures no breakups and a smooth operation. One of the most amazing things about the QC-twentyfour is its unbelievably wide frequency range: 5-50,000Hz is practically more than almost any piece of audio equipment can work with, except for the computer software, that mathematically can handle anything. Besides this simply awesome specification, the QC-twentyfour has a massive 15dB line stage gain and a 0.2% total harmonic distortion.



Needless to say that the QC-twentyfour will work seamlessly when in conjunction with pieces of equipment such as Quad II-Classic or II-fourty; for the most demanding ears, a Quad all-valve system could very will be one of the closest-to-perfection pre/amplification stages ever conceivable and with constant care such a system could very well surpass the lifespan of its owners...
