Post Subject: Pure Power 3000+Posted by Amir on: 8/5/2019
I have connected My Audio Note DAC 5 to EAR HP4 Headphone Amplifier and I hear the sound from My Sennheiser HD800. the Source is Computer .
Sennheiser HD800 is not easy load for HP4 and i think HD800 is very very bad sounding Headphone.
it is interesting that Audio Note DAC 5 shows the quality of AC more than other Components. I do not why but it seems Audio Note PSU filter is different to other designs.
Pure Power 3000+ spectrum shows some harmonics around 20khz and the Audio Note DAC 5 does not filter those harmonics completely.
I will publish the spectrum if you need it.
the interesting thing is Pure Power 3000+ Sensitivity to AC quality. when the AC is good then the Pure Power has very smooth sound with great transparency and when the AC is not good the Pure Power 3000+ has less transparent sound with a-little (very minor) harsh sound.
1. I think Pure Power 3000+ is a wonderful Product but the Main AC quality affect it's sound.
2. different components has different PSU filter design and react different to AC quality.
the Pure Power 3000+ has a option to connect a huge battery bank to it. it may help for very bad days.
I have used two Pure Power 3000+ in series but the result was not good.
I have checked My system for ground Loop and there is no ground loop in my system and My PurePower 3000+ is 100% OK (it has no noise).
