Despite the different opinion in some comments, the design, the quality of the components and the construction and finally the sound performance are well above the asking price, even with the filter in place. The performance-price ratio is simply excellent and is mainly due to the quality of all the components used and the assembly which is well above the entry-level category. In terms of sound, expect an improvement across the spectrum, with a fuller and clearer low end, cleaner mids and highs and a more three-dimensional stereo image with clearer instrument contours. Perhaps the most important thing is that all of this happens without any noticeable penalty in dynamics which is the usual case even in some of the 2,000€ filters that I have tested. Highly recommend, especially at this price point. My system: Eversolo DMP-A8, AUDIOPHONICS HPA-DM750ET and AP300-S2503E (I prefer the later!!!), Focal Electra 1028 Be
