This is a different kind of smoothness, SP200 doesn’t roll-off anything in the frequency range, this is just how your music is supposed to sound when you take out all the distortions and noise floor. So, I am observing an unexpected outcome on the sp200. This is where SP200 is shining brighter than other headphone amps, it feels at home when it comes to resolution. System matching is crucial with SP200, you really need to love your source as it will enhance all its sonics, including its flaws.

To test SP200 at its maximum potential, a super linear and honest sounding source with close to zero colorations was needed, that is why I used a Matrix Audio Element X. I will be testing the noise floor with FiiO FH7 and with Simgot EN700 PRO IEMs, the transient response will be tested via Quad Era-1, power output, control and linearity tests would be done via Hifiman Arya and I’ve thrown a Sennheiser HD660s into the mix as well, just for fun.

I am not that lucky by nature so obviously I forgot to pre-order one and put my hands on it. The only thing that bothers me a bit is how easy I can turn the volume wheel, it has very little mechanical resistance and sometimes I just raise the volume way too easily to uncomfortable loud levels. I consider it linear sounding without putting an emphasis on anything. What I really like about THX AAA amps is that they have their noise floor undetected at any volume levels, but will see about that very soon. With Erzetich Thalia or Sennheiser Momentum 3, it’s a child’s play, it will power them all easily without breaking a sweat.

With portables like Sennheiser Momentum 3 and with Erzetich Thalia I can go higher, maximum to about 10 o’clock position and that’s it. It makes THX headphone amplifiers more affordable and gets rid of clutter on your desk to boot" - Amir on ASR. At the same time, I remembered how good my former reference Gilmore Lite Mk2 from Headamp sounded, or the Burson Fun or even the cute Bacillus from Erzetich Audio, all were small but huge in terms of sonics.
