The Hans Beekhuyzen Channel, internationally known on Youtube, had the privilege of publishing the first review of our new PA1 mono block power amplifiers. Hans talks about the PA1’s functionality and the technique under the hood and then clearly outlines his opinion on the sound quality:
“The stereo image is wide and deep. Spaces between the instruments are well defined and the background is pitch black. (…) Dynamics are perfectly rendered as are microdynamics. We could never hear any coloration on any instrument and no instrument influenced other instruments.”

His payoff stunned us:
“Don't go to demos if your budget is too tight, for you will be sold within 3 minutes and then you might need another 5 minutes to admit you're sold.”

Soon we will start to ship the first units to more reviewers and dealers. Stay tuned…

LUMIN FIRMWARE 23 IS OUT NOW FOR ALL MODELS

--- VOLUME LEVELLING ---

The versatility of music streaming allows seamless mixing of local files and multiple streaming services, but it can introduce frustrating shifts in playback volume.

With Firmware 23, LUMIN extracts the native ReplayGain and loudness metadata from your files, TIDAL, Qobuz, Amazon Music, or Plex streams. It then automatically applies a precise, hardware-level gain offset that preserves the complete integrity of your music.

--- HOW IT WORKS ---

Off by default: Enable via Settings > LUMIN Settings > Volume Levelling.
Target profiles: Choose between Normal (-14 LUFS) or Quiet (-19 LUFS) (Loudness Units Full Scale).

LUMIN reads the native ReplayGain metadata embedded within TIDAL, Qobuz, Amazon Music, Plex, or local files containing ReplayGain tags. It uses this information to automatically and losslessly adjust the LUMIN volume on a per-track basis.

Models with a built-in DAC: This volume adjustment is done losslessly before the DAC/preamp stage.

Models without a DAC (Transports): LUMIN applies proprietary Leedh Processing Volume algorithms for bit-perfect digital output to your external DAC.

--- COMPATIBLE PLAYBACK METHODS ---

LUMIN Volume Levelling applies to:

- LUMIN App playback of local files (with embedded ReplayGain tags)
- LUMIN App playback of TIDAL
- LUMIN App playback of Qobuz
- LUMIN App playback of Amazon Music
- Plex playback directed to LUMIN hardware*

Note: Volume Levelling does not apply to third-party streaming apps, such as TIDAL Connect or Qobuz Connect.

*Plex users must enable "Analyze Audio Tracks for Loudness" within their Plex Server Library settings.

Sometimes a system quietly steals the show without making the biggest noise beforehand. It's often the products you stumble across in a demo room that stay in your mind long after the event.

JPLAY is an audiophile oriented music playback and control app for iOS and MacOS. With today’s JPLAY v1.4.3 update a full integration of the app with our MU1 and MU2 streamers is achieved. The MU1 and MU2’s UPnP interface supports ‘UPnP Eventing’ and JPLAY embraces this method in their latest release. As a result the JPLAY software receives information about a status change of the MU1 and MU2 streamers, such as upon a volume change or a pause message via the main k**b, the IR remote or the GRUI web interface. Since the status communication is now bidirectional, the user will experience a seamless integration. JPLAY configures all settings automatically when it streams to a MU1 or MU2, which ensures a smooth operation.

Grimm Audio is very happy to join the JPLAY Certified Partner Program, which guarantees that JPLAY is tested on stability, compatibility and performance on the MU1 and MU2.

“We love to offer our customers a rich user experience and so we are thrilled that JPLAY now offers full integration with the MU1 and MU2. JPLAY is without doubt one of the finest hi-fi apps on the market and it’s great that it became a natural extension of our products,“ said Eelco Grimm. Marcin Ostapowicz, founder of JPLAY, responded: "Working with the Grimm Audio team has been a pleasure — they care about the details the way we do. With Eventing in place, the MU1, MU2 and JPLAY now behave as one integrated system, whichever way you prefer to control your music.”
