FAQs

Please read our FAQs page to find out more.

Is it mandatory to connect the turntable’s ground wire to the BOX X5’s ground terminal?

Grounding is recommended to avoid rattling during use.

Can the BOX X5 be used as a regular preamp?

The BOX X5 is a phono preamp with a higher amplification gain than a regular preamp, thus it is not suitable for use as a standard preamp.

How to power on and off to prevent any thumping sounds that could damage the equipment?

Power On: Turn on the turntable, then the BOX X5, followed by the amplifier.

Power Off: Turn off the amplifier, then the BOX X5, and finally the amplifier.

What power supply is used for the BOX X5?

The BOX X5 is powered by its supplied AC adapter, not a DC power supply. DC power supply filters cannot be used for AC power supply.

I have been listening to this since 2:00 pm.
It arrived maybe 30 minutes before then.
Understand, this is very initial impressions.
It sounds fantastic! I have pkayed 4 albums.
Chet Baker's Touch of Your Lips, Donald Byrd's Kofi, Bob Marley & The Wailers Exodus, and Bill Evans Trio Waltz for Debbie. This through a Prima Luna Evo 400 Intergrated Amp with a Vintage Sansui FR 4060 turntable through Vandersteen 2 Ci's with a pair of REL Classic 98 subwoofers. I would certainly consider buying one to upgrade any receiver with a built-in phono stage.
This is a home run, Fosi Audio!

Cute Phono Preamp

Sound is stable and reasonable. May I would have added a subsonic filter. The X5 amplifies a lot and I had some microphoning in the beginning un my mm cartridge. Moved my turntable further away from the speakers and lowered volume as much as Ih could. Now everything is +/- great. I can recommend this phono preamp.

Great item. What a wonderful performance this little baby is able to provide. After a little time of burning in this honey makes it unbelieveable good. Buy it!

Deze fosi pre amp helpt me mijn vinyl collectie opnieuw te ontdekken. Ik luisterde vinyl via de mm-aansluiting van mn Marantz PM7000n maar dit is echt een wereld van verschil. Met name op het gebied van stemmen, dynamiek en een open geluidsbeeld.
