Here’s a new feedback today from a customer who sent iBasso DX220 with AMP8/AMP9 to apply Fidelizer Masterpiece Mod on another day. Here’s his shared his feedback in Head-Fi today as below. 🙂

Been trying out the DX220 + AMP9 Fidelizer Masterpiece mod this evening. Very impressed! I try not to rely on my memory for music – especially the amount of time it’s been to send the DX220 there and back. I compare to my iPhone, and there definitely appears to be a better/larger difference than before. Everything appears to be a little tighter and better placed – and just feels more enjoyable. The differences are noticeable with the CA Solaris, and even more so with the Focal Stellia. I tend to prefer the Solaris for the exemplary bass (it’s just right for me), whereas the Stellia win for clarity, imaging and amazing soundstage. The hiss is still there with the Solaris. The Solaris doesn’t sound quite as good with the DX220/AMP9 Modernizer as my main amp, but the difference isn’t crazily huge (which is a surprise considering my main tube amps are crazily huge!).

Edit: wife just grabbed the Stellia and DX220/AMP8 mod before I could even listen properly, and once was listening, smiled and said “I’m listening to these, you can go upstairs to listen to those big amps with those uncomfortable headphones (LCD4)”. Don’t think I’m getting it back this evening…

Well, I’m not sure if he gets it back now. On positive side, Fidelizer Mod seems to improve his wife’s acceptance factor quite effectively. 🙂
