I changed also the stock fuses in rHead and in power supply (Farad Super 3) with hifi-tuning supreme3 silver/gold ; there was a slight difference in sound quality (after 300 hours).The biggest difference in sound quality was when I changed the power supply.

The fuse have printed a direction and the producer recommends to install the fuse in the direction flow the current.

Is the correct direction of the fuse ?

Nice! We’re waiting the pictures and with your impressions about sound quality.

Hello, Does anybody know the direction of fuse? Does it slow blow or fast blow? I wish to change it.

My collection of portable devices from top to the bottom: 1.xDuoo X20 DAP 2.Lehmannaudio Traveller headphone amplifier 3.Chord Mojo(I)/Poly (DAC/Amp/Streamer) 4.Meier Corda Headsix silver headphone amplifier (limited edition- only 200 pieces) 5.Fiio X5(I) DAP.

My portable rig: Chord Mojo(I)/Poly, xDuoo X20, FiiO X5(I), Meier Corda Headsix (limited edition), iPad Pro, Hifiman Sundara (with Dekoni Fenestrated Sheepskin pads and Lavricables Ultimate cables).

Actually the power supply can change the sound of the rHead…I changed the standard power supply with a linear power supply Farad Super3. The benefits of this upgrade is a black background, deeper bass, wider soundstage.

I wish to purchase a Fostex HP-V1 tube headphone amplifier and I am wondering if I could use a different power supply than stock one; the Fostex it's rated 15V but my Russ Andrews powerpak pro power supply it's rated 16V. It's safe to use it?

Hi guys, I own this beautiful headphone amplifier; I use it mainly with my Fiio X5 (I) DAP but unfortunately the X5 battery has gone…. so I’m looking for a new DAP to replace my old X5. I wish a DAP with clean output line and good DAC’s, not necessarily interesting in Android or Linux DAP’s...

After more than one week of burn-in I can confirm that the sound improved; bass it’s tighter, deeper soundstage and well defined.

Until now I like better the DC iPurifier2 with the original Arcam power supply.
