A worthwhile upgrade but beware of almost criminally terrible lack of an instruction manual
4 Stars
A worthwhile upgrade but beware of almost criminally terrible lack of an instruction manual
BEWARE TO ALL BUYERS:the USB outputs are for the D50/D50s, the other output with the round power adapter on both ends are for the DX3 and I believe the A50. NOWHERE in the manual does it specify this. I plugged the Round adapter into the Input AC socket of my D50s and the D50 display said "Protect". I checked the fuses within the P50 and there were good. I web searched on why the D50 went into Protect mode and didn't find anything. I looked at the back of the P50 and saw it had 2 different output voltages and that the USB was lower at 5v and the Round one is 15volts. Basically the round one will potentially fry your D50s if the protection circuity fails to work. Luckily for me, it did its job and didn't fry my D50s.With that out of the way, I purchased the P50 to run my D50s which is in my second system. I run a Topping D90MQA in my main system and it is fantastic. I don't do a lot of critical listening in my second system, but I decided to see if the P50 made any improvements.Long Story short, it does. The D50s does at time have some edginess which translates to me as hard to listen to for long periods. With the P50 supplying the power, images moved more into focus I suspect this was due to a lower noise floor, a quieter blacker background. My system is fairly resolving and still costs an arm and a leg, so, perhaps with a more basic modest system, the P50 won't do as much. I would say that if you have a relatively high end system, the P50 is a worthy bang for the buck upgrade.Lastly as point of reference, I was using an older Apple power supply vs a cheaper wall wart thing. Even so, there was a nice improvement. There is a good video on Youtube where the person suggests, the Apple Power supply gives you about 80% improvement over the basic wall wart , and the P50 gives you that extra 20%. I would tend to agree with his conclusion....so, you get to 80% using or finding a Apple adapter for around $10-$20 used, or spring $120 for the P50 . Depending on your budget, both are worthwhile.

5.0 out of 5 stars Gut für hochohmige Kopfhörer
Reviewed in Germany on May 29, 2021
Perfekte Verarbeitung und hat alles nötige beigelegt. Sehr angenehm ist, dass wie auf dem Bild zu sehen das P50 nicht im Stack betrieben werden muss, da zwei 15V Kabel beiligen, wovon eins auch etwas länger ist.

Aber nun zum wichtigsten, dem Sound.
Am Ende des Tages ist es nur ein Netzteil ABER es gibt einen Unterschied für hochohmige Kopfhörer im sub 120Hz Bereich welcher spürbar präziser und fester ist. Bei meinen DT1990 hat es einen Unterschied gemacht, allerdings für jägliche effizientere Kopfhörer wie Grado oder Audeze kauft den P50 bitte nicht.
