[Power Pop 23]

That price is incredible! Talk about fire sales. I wonder if something seriously wrong with that product. Makes you wonder.

Agreed.

With fulfillment by Amazon USA, there is a 30-day window for returns.

No, it's great.
Almost all of these amplifiers go on sale from time to time. I also bought the Douk A5 for 50 euros.

 

[Hellboy.]

Amazon say "The adjustable High-Pass Filter (60Hz,80hz,100hz,120Hz) protects your main speakers" ???
But i don't think this one have HPF. The one with HPF is " O-Noorus D1 PRO".

Yes, several inconsistencies like that need clarifying.

Might be perfectly legit...

Considering that a 36V 5A power supply costs $25 - $30, the amp and power supply for under $50 seems like a screaming bargain.

I wasn't looking for another amp, but I couldn't pass it up. I'll find out how much of a bargain when it arrives in 2 weeks.

Welcome to ASR,

Let us know how much of a bargain it is.

Thank you

I'm a little scared that you put "bargain" in italics, but I will.

And, if you have a Prime VISA card you can save another 5%. What's not to like - even if you use it for a set of outdoor speakers on your deck. Although it comes with only a 36VDC PSU, I wonder if it's spec'd for use with a 51VDC PSU? Update: Yes, I just confirmed it can handle a 48VDC PSU.

Is this all sensible and economical?
Probably not, but I enjoy it.

Who cares. What an ingenious solution to the heat issue. Sure, it might look 'fugly', but you can always tuck behind something on a lower shelf.

I received my D1 today and just hooked it up. It does have the fixed 80 Hz subwoofer LPF, but it doesn't seem to have a HPF for the L/R speakers like the D1 Pro does.

It gets slightly warm using the included 36V/5A power supply when listening at moderate volume; certainly not hot.

I don't have the ability to do a proper A/B test to compare it to my RSL iA255.1, but I think it sounds pretty good, especially for such a cheap price.

Hello ebsebs

I’ve owned an O-NOORUS D1 since its official release (over two years ago); I’ve never encountered a single issue with it, and it still works perfectly, even though it is never fully turned off (it always stays in standby/IDLE mode).
One of my daughters "inherited" it, and she is completely satisfied with it

I also own an O-NOORUS D4 as well as a D3 Pro (also since their release), and these amplifiers give me the same satisfaction as the D1 model
