Know before you buy
Purifi Eigentakt technology significantly reduces noise and distortion to near-unmeasurable levels, regardless of the frequency or load. This results in a highly transparent sound that maintains its character even when driving difficult or low-impedance speakers.
Yes, the M23 is an excellent choice for high-end stereo or multi-channel systems. Because it is bridgeable, you can configure it as a 700W mono amplifier if you need extra power for demanding center or front speakers.
No, the M23 is a dedicated power amplifier and does not include a DAC or volume control. You will need to pair it with a separate preamplifier or a streaming DAC that features a variable output.
A high damping factor of over 800 ensures the amplifier has absolute control over the speaker drivers, particularly the woofers. This prevents unwanted cone movement, resulting in tighter, more accurate bass response.
Yes, the M23 features both XLR balanced and RCA single-ended inputs. You can easily toggle between these connections to match the output of your existing preamplifier.
The gain control allows you to match the amplifier's sensitivity to your specific preamplifier or source component. This helps optimize the signal-to-noise ratio and ensures your volume control has a usable, comfortable range.
