The PALAB M1-Mini is a portable DAC/Amplifier that offers plenty of output power and a solid sound performance for such a small device. It has a pretty linear frequency response and a slightly warmer than neutral tonality.
This review is written after a burn-in period of about 80 hours and is based on my sound experiences paired with IEM’s like the Meze Audio RAI Penta, Campfire Audio ARA and FiiO FD5 and full sized headphones like the iBasso SR2 and HiFiMAN Ananda.
The PALAB M1-Mini offers a natural and controlled subbass reproduction and doesn’t adds any additional weight and rumble to the paired earphones/headphones. For example the Campfire Audio ARA shows a pretty linear subbass character with average depth and intensity which has been reproduced unchanged when paired with the PALAB M1-Mini.
The midbass region on the other hand shows a tad of coloration that is not overdone. This region sounds detailed and has a great sense of authority, control and speed while listen to IEM’s like the Meze Rai Penta and FiiO FD3 or full sized headphones like the iBasso SR2 or HiFiMAN Ananda. Instruments like trumpets or the contrabass up to synthetic bass notes in electronic music do sound pretty controlled and do shows a good amount of weight, body and intensity.
The lower frequency region of the PALAB M1-Mini portable DAC/Amplifier is in general pretty controlled, detailed and offers a good level of layering and extension when paired with high end earphones of headphone without to show any remarkable negative conditions like a midbass hump, unwanted roll-off or situations like muddiness or mixings.
The PALAB M1-Mini shows an impressive performance in terms of airiness, detail retrieval and clarity of the midrange region. The tonality of this area sounds with all earphones & headphones that I have paired with it, slightly warmer than neutral due to a slightly coloration in the lower midrange area. The
Vocals & Instruments:
The lower midrange has a good sense of depth and body which is an advantage while listen to instruments like acoustic guitars and hi-hats or male vocals like Barry White and Isaac Hayes that do sound pretty emotional and intimate, especially with IEM’s like the MEZE Rai Penta and headphones such like the HiFiMAN Ananda.
The upper midrange of the M1-Mini offers a nice sense of transparency, openness and detail retrieval. It seems like that the sound engineers of PALAB where quite successful while tuning the ES9038Q2M DAC chip.
Female vocals from Dionne Warwick to Edith Piaf do sound lively with the ARA and FD5 and quite emotional and intimate with the Rai Penta and Ananda, while the upper midrange tuning adds instruments like pianos and organs a nice sense of presence.
Upper Midrange and Treble:
The PALAB M1-Mini has a very detailed and clear upper midrange presentation with an above average level of extension. The upper midrange of the M1-Mini gives the overall presentation a good level of vividness and transparency and shows also a pretty natural timbre.
The upper midrange transition did sound pretty controlled without to show any noteworthy audible negative conditions such as over sharpness/brightness with all IEM’s and Headphones I have paired with it, which is a remarkable plus point of the M1-Mini.
When it comes to the treble range I can say that the PALAB M1-Mini shows an above average performance in terms of speed, separation and extension. The lower treble area shows a nice sense of presence. Instruments like snare drums do sound crisp and clear with both the Campfire Audio ARA and HiFiMAN Ananda, while soprano voices are reproduced with a nice sense of presence and clarity.
The upper treble region of the PALAB M1-Mini offers a good amount of treble brightness and sparkle. The performance of the M1-Mini in terms of airiness and sparkle in this area while listen to the MEZE Rai Penta or FiiO FD5 was quite impressive.
For example, treble intensive instruments like hi-hats are distinctive and are presented with a pretty successful level of extension, while crash and ride cymbals do sound quite clear. What I really like about the treble character of the M1-Mini is that it shows a very good level of speed and control in complex genres like Metal and Jazz, and is also fatigue free with other genres like EDM or Pop music.
The PALAB M1-Mini is a pretty successful portable DAC/Amplifier in terms of vocal & instrument separation and imaging. The soundstage of the M1-Mini sounds quite airy and spacious, with good sense of wideness and successful level of depth.
PALAB M1-Mini versus FiiO Q5s (with the stock AMP Module):
Both devices are portable DAC/Amplifiers with a wide variety of connection options, while the PALAB M1-Mini stands out with its smaller form factor, High End DAC Chip (ES9038Q2M vs AK4493EQ) and independent power supply port. The FiiO Q5s on the other hand offers BT connectivity, a build in battery and an interchangeable amplifier section.
When it comes to the sound performance I can say that both devices do show a performance that really stands out for their price (449 USD PALAB M1-Mini & 349 USD FiiO Q5s).
The lower frequency region of both devices shows a pretty natural and detailed presentation with good control and authority. The main difference is that the FiiO Q5s shows slightly more subbass depth and extension compared to the PALAB M1-Mini that has the slightly edge in terms of control. The midbass region of the FiiO Q5s shows a tad more intensity and fullness, compared to the PALAB M1-Mini that has a more linear response with better sense of authority in this area.
The midrange of the PALAB M1-Mini shows a slightly more neutral tonality and a more forward oriented and intimate character, along with a higher level of clarity and airiness compared to the FiiO Q5s that shows a warmer and more musical tonality.
The lower midrange of the Q5s has slightly more intensity, depth and extension, which is an advantage for male vocals or instruments like trumpets and acoustic guitars. The PALAB M1-Mini is the winner when it comes to the upper midrange performance that is more pronounced, detailed and has a better sense of extension. This makes it more successful with female vocals and instruments like violins and side flutes.
The treble range of both devices shows a very good performance in terms of control, detail retrieval and extension. The PALAB M1-Mini has the slightly edge in terms of clarity and definition of the lower treble region and airiness and sparkle that is produced in the upper treble region.
When it comes to the soundstage performance, I can say that both devices are successful for products under the 500 USD price range in terms of separation and placement of instruments and vocals. The PALAB M1-Mini has a slightly advantage when it comes to the soundstage wideness and airiness, while the FiiO Q5s has the upper hand in terms of depth of the stage.
PALAB Audio is a relative young company in the world of Audiophile equipment’s. But this doesn’t change the fact that the M1-Mini is a small but powerful DAC/Amplifier with a great build quality and solid sound performance, thanks to well implemented components such like ES9038Q2M High End DAC Chip, XMOS U11690C20 Multi Core Controller, Balanced Output Design, etc.
Pros and Cons:
- + Impressive Sound Performance
- + Great detail retrieval from the Top to the End
- + Output Power (110mW @ 600 Ohm)
- + Very Small Footprint
- + Solid Build Quality
- + Lots of Output Options & Indented Power Supply Port
- – No built-in battery means drain of your source (if you use it with Smartphones, Tablets, etc.)
- – White Noise over the 4.4mm output, noticeable with sensitive IEM’s (ARA & Solaris 2020)
- – Warms up a bit If you use it with power demanding headphones (maybe not a real con)
Thank you for the Read!
