The next generation is here, now named the m801mk2. Newly designed amplifier circuitry adds to the features of the previous versions while significantly improving noise performance at low gains, increasing low frequency bandwidth for improved phase response, improving RFI/EMI immunity for today’s ever noisier world,⁴and eliminating the external DC power supply for a cleaner, simpler design.⁵

Today’s modern recording studio is invariably loaded with incredible sonic processing capability, making the opportunity to add great sounding color routine. But capturing the magic at the front end is still the job of skillfully designed analog hardware, for which there is no substitute. This makes our preamps more relevant than ever. If your source sounds great and your mic is plugged into the m801mk2, you’ll be rewarded with a recording of breathtaking depth and realism. If you choose to color it up from there, you’ll be starting with the best possible raw material you can get.
