>>I am brazilian and I speak portuguese, so forgive my english, I’ll use translation tools to help<<
INTRO:
I’ve seen music move from vinyl to cassette, then to CD, and finally to streaming… (yes, I think I’m getting old). I have plenty of stories to tell that came about thanks to CDs.
In a world where things are becoming increasingly digital and virtual, the Fosi Audio Merak CD player is the tool that can bring back the days when music – in a certain way – was more physical.

UNBOXING:
PHYSICAL ASPECTS:
Construction:
- Excellent build quality.
- Made of metal (material not specified by the manufacturer).
- I couldn’t tell if the transparent section is glass or plastic.
- Compact, lightweight, and transportable.
- Aesthetically very pleasing (subjective).
- Manually operated lid.
- Slider-style volume control (vol – / vol +).
- OLED display showing playback information.
- Adjustable display brightness via remote control (3 levels).
- Remote control (requires 2 AAA batteries, not included).
- The remote could have been rechargeable via USB (IMO).
- The remote works at a range of about 7 meters.
- USB-A to USB-C power cable.
- The cable has a PVC coating and tends to retain creases.
- It could have been a Paracord cable (in my opinion).
Features:
- Volume control: increase or decrease volume.
- CD Ripping: extracts audio from the CD and converts it to a WAV file.
- ESP Anti-shock: buffers 60 seconds of the track to prevent interruptions caused by vibrations.
- 4 Playback modes: play once; repeat one; repeat all; random.
- Gapless: eliminates empty time between tracks.
- Lid-Open Auto Stop: playback stops if you open the player’s lid.
Characteristics:
- It didn’t present abnormal heating.
- Audio extraction takes the same amount of time as CD playback.
- E.g., if a CD is 60 minutes long, the ripping process will take 60 minutes.
- To save the ripped files, the USB flas drive must be formatted in FAT32.
- Files are saved in WAV format with a constant bitrate of 1411 kbps.
- It can play files from a USB drive, but it doesn’t read folder structures.
- It supports USB flash drives up to 128 GB for playback.
- It supports USB flash drives up to 32 GB for ripping.
- Volume scale: 32 steps.
- Supports SACD (only those produced on CD media).
- 12V Trigger output: power supplied directly from another amplifier.
- The in line and optical outputs always operate at maximum volume.
