smart Posted August 15, 2021 Posted August 15, 2021 (edited) Further information: C2300 Vacuum Tube Preamplifier is the long-awaited replacement to the C-2200 valve pre-amp. It combines a suite of potent engineering enhancements with smart, user-programmable features to deliver a truly extraordinary audio preamplifier. Each input may have the bass, treble, and mono/stereo mode adjusted and stored in memory. When individual inputs are selected, these settings will engage as preset by the listener. All adjustments may be made either from the front panel or remote control. Two 12AX7a Vacuum Tubes are used for each of three sections: the Moving Magnet phono section, the Moving Coil section, and the high-level preamp section. Its phono sections are fully adjustable on the fly, so the listener may change impedance or loading settings as the record plays. A high performance headphone amplifier with a 1/4" headphone jack is included.
