      No the Sundara won't be powered accurately, it may get loud but will not sound it's best as it will 9n more powerful amps.

    I know you said these may not power planars all that well, but the P1 Max seems really sensitive to me, easiest to drive thing I own and I power it off my galaxy s8 as of now. But I am about to get a phone without a 3.5mm and I was looking for something reasonably priced but competent for the P1 Max and this seems quite good for the money so I question now if it is good enough based on what you said.

    • @TheHonestAudiophile
      @TheHonestAudiophile  ปีที่แล้ว

      I prefer the Hiby FC4 with the P1 Max. The 71 will get the P1 Max loud but it seems to lack sonically to my ears. Planar are picky when it comes output power imho.

      I don't understand what you mean by reducing the noise floor. I don't have any issues with impedance causing there to be hissing or distortion when playing sensitive IEM. I can't connect directly to my phone as it doesn't have a headphone jack.
