Where did you get so many opamp cards?
Support does not respond, Ali sellers says that manufacturer does not sell this parts separately.

Can you send a couple of cards? DM me

It is recommended that you directly send an email to contact the manufacturer after sale, and it is expected that it can be purchased. Each person is limited to 2pcs.

They simply does not respond... All other sellers saying that manufacturer does not sell OP amp boards.

You can find a Chinese person to help you buy. Use China's chat software: wechat ~ add the manufacturer's after-sales staff's wechat account (tell15818730806), contact to buy one, 50 yuan each.

Various attempts ~ Easily replaceable operational amplifiers and filter capacitors

Very good workmanship, can you briefly describe what you have done in each image and the affect on SQ.

The Sparkos with risers won’t go in straight like the other op-amps. Just tilt the opamp board in an angle while inserting and it will go in. Don’t apply any force, it will go in easily once you find the right angle. It’s a tight fit.

Give it a try. If it still doesn’t work, I can try to take mine out and show you.

i cant fit sparkos +riser each side, but can fit easily with only 1riser.. can u share the vid how you do that with 2riser?

It seems to be dependent on if you're a resident of China. If not, here is pretty much all you have.

Enjoying the discussion on the XDuoo Xd-05 Pro but have a couple of questions for the forum. I am looking at either the Q15 or the XDuoo XD-05 Pro (yeah, decent price difference)
Has anyone tried the FT3 350 Ohm headphones with the XD-05 Pro? And if so did it drive them well? Sound impressions?
Is the XDuoo €350'ish better than the Q15?
Sources are Fiio M11 Pro, Hiby RS2, Sony ZX300, laptop and Android phone.
Headphones/IEMs are Beyerdynamic DT1990 Pro, Hifiman Sundara Closed and HE4XX, Sony MDR-Z7M2, Dunu SA6, Fiio FD3 Pro, and (soon) FT3 350 Ohm.
Any advice or info would be greatly appreciated.
Thanks in advance

The Fiio Q15 will struggle to power your DT1990 Pro's to their full potential. My Q7 is on Ultra High Gain when using my DT770 80 OHM Beyer's

Ok, thanks for that. I normally use the Beyers with a XDuoo TA-20. Looks like the XD-05 might be the better option.

I can only compare to my HD650 (300ohm). XD05PRO drives them really well. Using at NOR setting 6.3 output and 45/100 volume

The hardest headphone that I tried was H800S, and XD05PRO also drives them with TURBO gain and 60-70% volume.
