As promised a bit of my experience. Well, firstly, the potential for improving amps is significantly limited and quite expensive. But the fact that mad craftsmen can significantly improve the sound of their ibasso devices is undeniable. Okey, let's go. So the capacitors were replaced in the power supply. It was 1000uF×2 6.3 v nichicon fw. It became 1500 uF×2 6.3 v organic electrolyte. And capacitors in the aisle. It was 22uF×4, became 47uF×4 16v (Elna silmic 2 or nichicon es nonpolar green)or 100uF×4 6.3 v nichicon fine gold. The power supply is considered you need to assign the capacity. Well, actually in the aisle will not interfere with 100uF, although 47 well. But I still might try 100uF silmic2. Soft absorber EMI I have not installed, expensive and nowhere to buy fast. Tried to bypass power and aisle. I believe that this is not appropriate. Although power can be shunted. A aisle does not need to be shunted and even probably harmful. And not fit all of these shunts there. Fine gold excellent capacitors if you like warmth deep and soft bass, not straining high frequency and high-medium frequency, low male vocals and soft female vocals. Silmic2 is good resolution, fine high frequencies but weak bass and bright high-mid frequencies. Nichicon es excellent resolution in all frequency ranges, faster and deeper bass than with silmic2, but less deep than with FG. I'm still on the ES. But now I am listening to the player more often with TFZ galaxy t2. T2 softer headphones and cable I have a hybrid copper-copper-silver plated 2.5 mm. But with Tfz tequila 1 player sounds a little bright. Most of all I liked the combination of tequila with FG. Or rather with tequila es is also good and very atmospheric, but a little bright. Bright also with tequila and silmic2.
