I cannot seem to be able to connect any power adaptor to the P20 other than that it came with. I have several power adapters around with the same plug size but they just refuse to enter, as if they were too large. On the other hand, the loxjie's just plugs to any other socket.
Someone else had this problem?

My own experience:
The P20's power connector is 5.5mm x 2.5mm. I upgraded to a 12V/6A power supply and had to add a female 5.5x2.1mm to 5.5x2.5mm male adapter.
This adapter was bought on a electronics hardware shop.
Hope this helps

Thank you! I'll try to fetch an adapter.

I have the P20 on an A-B test setup next to an SMSL SH-9. Running a few days now. It's been fun. They are very similar on tracks that I can really listen to the soundstage and echo-y details.

did you upgrade tubes?

 

[ShaolinGrump]

I am tube rolling. So far:

Russian 6N3P-E
Sylvania Gold Brand JHS 5670 on socket savers
GE JAN 5670 (on order from an eBay Chinese vendor

The stock tubes were least impressive. Not noticing the difference yet between the Russians and the Sylvania.

I'm running a pair of GE JAN 5670W from 1987 and these make the P20 sing.

Running the p20s on stock tubes are just... nah. I run mine with 6N3P-DR russian tubes and they were wayy better than stock, better extension on both ends of the spectrum, better detail with very tight and sufficient bass.

After purchasing some 6N3P-DR tubes and listening for a while, here's an update to my original post/review on the Loxjie P20. I'll list the tubes I've tried in the order I like them from 1st to last:

1. GE 5670 5 Star
2. 6N3P-DR
3. 6N3P-E
4. JAN-5670W GE
5. 6N3 (Stock)

While I like the GE 5670 5 Star tubes the best on the Loxjie P20, the 6N3P-DR tubes are a close second and they tend to be a bit cheaper. Hope this helps future tube-upgraders decide what to go for.

6N3P-DR are awesome, great tubes at a great price

Listening to The Yes Album ~ Expanded and Remastered on the Loxjie P20 being fed from a SMSL SU-8 DAC which is being fed from a NAD C542, full balanced from DAC to amp and a Periapt balanced cable to my HiFiMan HE400i.
P20 is utilizing a matched pair of 1968 Reflektor 6N3P tubes. For the money, a total of around $650. this system sounds very good and I am thoroughly enjoying it! Texture, detail, nice quick bass with no overhang and highs are clean and grain free. Great remaster of a classic BTW.

If anyone has used socket savers for their amp, does the one on the right stick up above the left one? I for one cannot push the one on the right further down

I had the same issue with mine before, the socket saver is not properly pushed down if that happens, try swapping the L and R socket savers

Ahhh yes! That seemed to have done the trick!

Thank you!

It is tricky to insert socket savers on this amp, indeed. First time I tried, one of the saver's pins did not get right into the socket and I had to take it off. Problem is that it would not come up. I had to disassemble the P20 and lever the socket off with a small screwdriver beneath the cover, because with the savers inserted, the PCB does not come out...
Most socket savers are of mediocre quality, with thin and ductile pins and cheap bakelite.
A great advantage of using socket savers, besides making it much easier to swap tubes, is to keep the amp cooler. And it really works with the P20.

And it also covers up those horrid blue leds that are bright as hell when in a dark room
