Here’s a new feedback today from customer who purchased Advanced ROM for DX200. He’s also considering about Fidelizer Mod for AMP8 module too.

The effect of your “DX200 Advanced DX220-ported ROM” is simply gorgeous! The sound is really much clearer, the bass are much deeper and extended but very clean and alive, the mediums and voices are very life-like (details, feelings of the singer), the trebles are very precise, more transparent, sound natural, detailed, fast and “dynamic”. Overall, it is incredible. The stereo image seems really neat, wider, and even deeper; the instruments of all sorts are pretty well located. Also, the instruments sound “free”, like if each of them had its own space of the exact dimension it “needs” to sound natural, sort of free. But despite this, the instruments are not “stepping over” each other; amazing. (The quality of recording starts to be audible at this point, which makes sense.) Even during the most intense part of different types of musics, all sounds keep pretty distinct, not muddy. Impressive! The music goes from very low level to intense volume super-fast but “in an effortless way”. And all that, while I am using flac files only of CD quality. (I guess I will have to consider using higher quality files…) I then though about you, Keetakawee, and I do not know how long it took you to develop this know-how, but, gee!, do you know your business! For about 12% of the official price of the DX200, your Advanced ROM literally wakes up the potential of this DAP and seems to “multiplies” its performances. And I did not get any hardware mod. Yet.

I’m happy to hear he finds Advanced ROM multiplying his DAP’s performance at fraction of its price. Advanced ROM users can get free shipping for first Fidelizer Mod product too. 🙂

 

Here’s a new feedback today from customer who purchased Advanced ROM for DX220. He shared his feedback after using free version for a while.

Apollo is quite good. It is more neutral than mango. Mango has increase booster in mid band region, focusing in vocal and the downside, it makes sound a bit muffled.

Overall your Advanced Rom improve clarity, blacker background, deeper staging. Good job.

Thanks
Regards

Apollo included in Purist ROM is a custom built version with my own code optimizations to improve sound quality. Feel free to try it and happy listening. 🙂

 

Here’s another feedback today from customer who purchased Advanced ROM for DX200. He shared his feedback after listening with Advanced ROM for a few days.

Hello again,

I did the switch ROMs test. 🙂 You are right, the advanced ROM is better!! I overall sound is more clear! I listened to a few songs in basic version and switched back to advanced. The difference was audible. I cannot understand why I was so disappointed in the first place.

The only I can think of is sound stage. I was impressed with basic’s sound stage. In advanced ROM I think it narrows the depth. Better Depth I hear with filter 5, My favorite. I also use no 2 No 7 is too stiff for My ears. Surely you have done a very good job Keetakawee!

Best Regards

Some improvements may sound subtle at first but after you listen to new improvements for a while, it’d be easier to notice the absent of new improvements. 🙂
