I actually just wrote a particularly relevant comment to this question on the LCD-5 thread. Pay attention to point 2. This is where susvara can run into a lot of issues on lower end amps that kinda have enough power but not realy (GSX-mini is a great example of that range) > [@Audeze LCD-5 - Official Thread](https://forum.headphones.com/t/audeze-lcd-5-official-thread/14588/581): > > ok, so a few things to consider here. These specs are almost always at 1kHz. As you change frequency the power requirements will change and can end up being quite a bit for lower bass frequencies (luckily the impedence of a planar is flat so its just a sensitivity curve). This part ultimately isnt all that important to overall outcome of a can/amp pairing IMO (I have some pairing I love that are theoretically vastly underpowered), but it is something to keep in mind. Power of an amp, generall… --- _[View the full topic](https://forum.headphones.com/t/hifiman-susvara-over-ear-planar-headphone-official-thread/2293)._
