Recommendations / Suggestions for one: Low power amp 5-15 W?

[DanielT]

Do you have any good suggestions for one?

Fine clean, low distortion watts. Operating from about 2000 Hz up to 17 kHz.

New or used amp does not matter. Can imagine up to 20 W, possibly......5 nice W might also be enough.

The amplifier will drive/power two:

Eighteen Sound - Professional loudspeakers

Sensetivity 109 dB therefore I need some with low effect. And an amp that does not make noise with such highly sensitive drivers.

I now use a tube amp of 6.7 W with them and it works well. But the tube amp is not mine therefore I am looking for a dedicated amp for them.

Edit:
I saw one like this that was sold a few weeks ago. 20 W amp. Maybe it could have been something?

I will build some DIY speakers with the XD 125. In addition to suitable bass / midrange drivers, I will also need miniDSP (fix FR) but right now I am thinking of a suitable LOW powerd amp for them.

B&O 50ASX2SE. It does about 22W@8R

mind the input impedance of the asx series, its horrible and partially broke 3 out of 4 outputs on my minidsp 2x4HD.

Check the MA12070 based one's.

Interesting! And it should have low noise. Not so much power in 8 Ohm, that was good. My XD 125 drivers is at 8 Ohm.

Wondering if it is measured with sufficient bandwidth? Some class D amps can be a bit hm si and so regarding distortion in the higher frequencies compared to class A and class AB.

It is small, physically small.That was good.

This is a review and detailed measurements of the B&K Components AV30.2 Power Amplifier. It is on kind loan from a member. The AV30.2 is discontinued but is available on the used market for low price I am told. I found one listing with asking price of $175 but not others. The good news is...

Yep, you should add a buffer.

Ha ha, I remembered this thread AFTER I just now bought a Rotel RA-920AX.
It will be as it will be with that amplifier. Bought it for $35 so I can always sell it for around the same price.

OR if I add a buffer. I'm not an EE, but an OP amp buffer looks simple on paper. It could even be a fun little project to fix one, but what is an infinite resistor that is mentioned in connection with Op-Amp Buffer in the link below?

Honor thy father and thy mother....with sound....

They had a receiver Luxor 5082R. They do not use the radio part but only play CDs. Ok, Luxor 5082R , totally ok for them BUT fixed positions on the volume control. They mostly listen to music at low level. Or they always do so. Problem then with the Luxor receiver, either a too little volume or too high a volume. Therefore, they get to take over the Rotel RA-920AX.

Damn nice combo, That Rotel amp together with speaker JPW P1(, 89 db sensitivity, 8 Ohm.)

Good damping factor for such a small, cheap amplifier:

At the time, it received good reviews:

I tried to turn that Rotel like hell, to see if I could hear any clipping but then my father started howling like a stung pig about the volume being too high, ha ha.

Infinite resistor here means you just omit it.
