Compared to NX4 DSD

Hi, I have Topping NX4 DSD and Monolith THX AAA Portable. Have been using NX4 DSD for 6 months, but after extensive reading about Monolith I bought it, and keep NX4 DSD as spare. I like deep bass a lot (drill rap mostly these days), but I prefer detailed, cold and analytical bass and sub-bass (not warm and boomy).



After trying Monolith, it is definitely an upgrade to NX4 regarding overall sound. I use it with Sony EX800ST (3Hz-20000Hz) IEMs. The sub-bass with Monolyth goes definitely deeper and cleaner, it is not boomy as with NX4 DSD+bass boost.



Another thing is that NX4 DSD has bass roll-off under 20Hz, whereas Monolyth is able to output 1Hz - 20000Hz. At the same time the detail in frequencies above bass is just insane compared to NX4 DSD, I actually started enjoying highs since Monolith as they are not cutting-in my eardrums as with NX4.



I have to agree that it all really depends on IEMs you use, Sony EX800ST can take 500mW, so the deep sub-bass under 20 Hz suddently sounds and also FEELS that it is there.



Battery stops charging automatically when full.



Please ask if you need any A/B.



p.s.



There is only one negative:



The volume control knob is really easy to turn in my pocket, so I have used a very thin black rubber band around the knob, all is 'safe' now.
