I just reviewed the Niles SI-2150 amplifier. This is a quick teardown of the same.
Here is the main entire amplifier in one shot:
General construction seems fine.
The heart of the system are the two UC250LP-M OEM amplifier modules from Hypex. An input stage allows variable gain (board in blue) and speaker protection relays.
As best as I can tell, that complicated switching power supply is by Niles as it matches the color scheme of the buffer board. Looking at the capacitors, we see that they are the chinese brand, Jianghai:
I can't get good information on them. They certainly are not a tier capacitor company but seems like a very big company producing capacitors. May be hard to replace them with other parts given the compact size required for the thin amplifier enclosure.
The Hypex modules use lower grade capacitors made by Samwah:
One nice thing about the modular nature of the Hypex amps is that should a fault develop in one channel, you can swap board and see if the problem is there or not.
That is all she wrote...

As always, questions, comments, recommendations, etc. are welcome.
Don't laugh but I have run out of socks! Have not gone shopping since beginning of pandemic back in February. Now I have no choice but to buy some but need money. So unless you want me to review equipment barefoot, please donate what you can using: https://www.audiosciencereview.com/forum/index.php?threads/how-to-support-audio-science-review.8150/
