M-LEY Passiv Stereo Tube EQ
Musical curves. Tube depth. Mastering-grade elegance.
The M-LEY Passiv is not about surgical correction — it’s about enhancing a mix through broad musical curves, natural tonal balance, and the unmistakable depth of a passive tube equalizer.
Its passive EQ architecture and tube amplification stage work together to add weight, openness, dimension, and refinement while preserving the musicality and integrity of the source.
NAM A2 Updated
All Tokyo Studio Capture profiles have been updated for the latest NAM A2 architecture.
NAM A2 represents the most significant advancement in Neural Amp Modeler to date, delivering substantially improved accuracy, efficiency, and hardware fidelity compared to previous generations.
According to large-scale blind listening tests, A2 consistently achieved results that are extremely difficult to distinguish from the original hardware.

- Ideal for mix buss, mastering, vocals, instruments, and final polish
Audio Demo
Compare the original hardware signal and the NAM profile across a range of sources — full mixes, vocals, acoustic instruments, drums, and more.
Each example demonstrates how closely the profile captures the tonal character, tube harmonics, and musical EQ response of the hardware.
The NAM and hardware samples are gain-matched to allow for a more accurate evaluation of the capture’s fidelity.
For additional context, a dry (unprocessed) version is also included.
Why this capture is different
- Multiple musical EQ curves captured for different tonal goals
- Passive EQ and tube-stage interaction preserved
- Consistent calibration across all profiles
- Designed for mix buss, mastering, and premium tonal enhancement
Waveform Comparison (Hardware vs NAM)
Below is a direct comparison between the original hardware signal and the NAM profile output.
This visualization highlights how accurately the tone, harmonics, and EQ response are preserved.
Technical notes
- Format: NAM (.nam)
- Sample Rate: 48kHz
- Capture Type: Real hardware
- Calibration: Studio-level gain staging
Gain Staging Advice
Our captures are pre-calibrated at -18 dBFS input level.
For best results, we recommend feeding the plugin with an input signal close to -18 dBFS.
Because many profiles combine EQ shaping and tube harmonic enhancement, some settings may appear louder or more open during evaluation.
Please level-match carefully when comparing profiles to better judge tonal differences rather than perceived loudness.
