Eversolo DMP-A8 Balanced Streamer/DAC Review

[jiji]

I'm facing a strange issues with V 1. 4.32 in my DMP A8 . All my playlist was vanished today. There were around 15 playlist I had until yesterday evening. Now only one playlist is visible. This doesn't sounds good, as I need to recreate all the playlist from the scratch now. ( I tried restarting 3 times, but it doesn't help). Don't know if anyone experience the same?
Also files in the library are missing sometimes , and then coming back after restarting.

Today i tried to do my FIR again in A8 and found if only using L and R sweping seperately, then the response is flat from 12 to 20kHz, but if i tried to sweep L+R combined, then it seems to be from 12 to 20 KHZ, its rolling off slowly. Don't know why? It doesn't seems to be cancelling out, but rolling off only in combined L+R response. Any suggessions why? May be due to independent eq selection?

I found the same thing when doing L+R measurements unless the UMIK is exactly in the middle/equidistant to the left and right speakers, measured by a laser. If I just eyeball it, the L+R rolls off a lot.

Hello, is here anybody who knows the output impedance of the preamp of the Eversolo A8.

It is important to choose the right poweramp.
Thanks

Your choice of power amp is determined by your choice or loudspeaker.

Something so well equipped and no sub out? too bad, that's a deal breaker for me.
