I have one , when I use it without sub , sound not good, but when I use it with sub ( 130hz , 24db/oct ) , it sound good, why I bought it? because in China it is very cheap ,about 200 usd mint condition

pa7 is 48v

Got the pa7 for 2days，sound great，mid to high very smooth？

as the pics show, mix the left 、right to any channel u want ,then EQ them separately

yes roon eq can control high/low pass for every channel , dm7 can adjust gain for every channel ,they work perfect to my ear in other room,but now my life changed , I can only put these stuffs in my bed room

roon eq High pass , Low pass -> topping dm7 8 channels dac -> speakers and sub(pascal powered sub)

as the @DVDdoug said , maybe the upper bass is reduced much, when I shutdown the sub , the speaker has no bass which they should have in other room

in corner the bass is much better

I can change the big mattress to a small bed like this，and put a thin matress on bed，is that help？

Hi guys，in pic is my bed room，I put a 150cmX 200cm ， 18cm thick mattress just on the floor，the bass sound reduced on the listening position

我在中国，我在 1 周前订购了 LA90D，但没有发货，所以我问了，他们告诉我“等待”

La90D is stopping selling on Taobao in China, the dealer just told me to wait , anyone know any message?

when I bought topping pre90 + Diy purifi 400(with very good measurement) , I guess maybe I should sell the 805 tube integrated amplifier ，but after months A/B listening ， I deside to keep them all , the tube amp in many albums sound better for my ear
