DEQX PreMate D/A processor/digital equalizer
I am unequivocal about my enthusiasm for the speaker-calibration capabilities of the DEQX PreMate. It made my very good speakers undeniably better, smoother and cleaner, and endowed them with a bigger soundstage. It made dense, complicated music easier to resolve, and all music more of a joy to hear. Add to that the PreMate’s DAC, whose outstanding performance was clearly revealed by feeding it a diet of standard and high-definition (up to 24-bit/192kHz) digital sources via its S/PDIF and USB inputs. The user must be prepared to spend time and pay close attention to learning how to apply DEQX, but the rewards will amply justify those efforts. A paradigm for future stereo systems should be the one I put together, with source selection, processing, control, DSP, and DAC all contained in a single remote-controlled component: the DEQX PreMate. I can’t imagine what more one could ask for.
