Integrated stereo amplifier with bass-management?
- Thread starter sarumbear

The Harman Amp's FCC:io has internal/external photos and the owners manual with basic specifications.
Internally it does not look like a product where raising the bar in audio specifications was a primary design goal.
The Harman product introduction sheet reads a lot like the Martin-Logan Forte and Paradigm P/W Amp sell sheets did. Integrators/Custom Home Installers are mentioned as a target market, not traditional audiophiles. This does not mean it will not sound or work well, but I would be surprised if it measured great.
Found a 2018 AudioXpress article on the Axign chip.

My NAD M3 has a hardware crossover that while not fully flexible in terms of micro adjustment does allow me to send the mains nothing below 40Hz in my case and then from the same preout section my two subs are sent the full signal to be adjusted at the sub. Not sure if the M3 would be a suitable recommendation, but for my 2.2 system it works quite well or perhaps I just don't know the difference. In either case I am content.

I cannot find a NAD M3, did you mean M33? If so that is four times the budget.
No, and my apology for adding noise to your thread. The M3 is discontinued, but it comes up used and is worth considering. It is an exceptional NAD design based on both subjective and objective reviews and it is built like a tank. I think it weighs about 65lbs. I shouldn't have polluted your thread mate, I did want to mention the M3 as NAD really did themselves proud with it and it can be found used for good prices, at least here in North America. I see it used from time to time. I actually bought mine used and have never regretted it. I actually use it as my headphone amplifier as I had some nice speaker tap cables made that allow me to drive headphones right from the speaker terminals.

Bluesound recently updated the Powernode, although I think the 2i would be suitable too.
Integrated amp
80 wpc
Volume slider on top of unit, otherwise remote or app
Analog input
Crossover from 40-200
One sub out
900 usd
Streaming and roon ready.
Hopefully I've managed to stick to the specs of the borderline intolerable OP.

This is a good review with measurements as well.

Do you mind explaining what you mean by that?

Thank you. It looks like it is an all analogue unit.
I had a good lough reading the review though.
I wonder should we tell the "reviewer" what midrange he had in mind which can operate down to 100Hz

the few used i found europe-wide are all way over your set budget, though (with the cheapest being around 1300€)

I think that you need in NAD C390DD (only used), according your budget.
Built on the basis of a FOUR-channel DAC with integrated DSP. Two DAC channels are used to output audio through the built-in Class D amplifiers, and the other two DAC channels work on two universal analog RCA outputs on the rear panel, which can be configured at will by the user for different tasks, for example, for biamping, if you add an additional power amplifier, you can set the filter cutoff frequencies per channel. Or as configurable outputs to subwoofers (stereo). The settings allow you to "stitch" the treble and bass bands in this case, both in volume and frequency. In fact, due to this architecture and a six-band filter, the device implements room correction. It can be adjusted to any acoustics and any room without further sorting of the components. Of the integrals of the NAD-s, only the next NAD M32 can do this. In the amplifier, you can insert the Bluesound BluOS streamer board into the MDC slot (optional) and it becomes an all-in-one device, respectively, with this implementation, the sound is transmitted internally in digital form over the I2S bus. The streamer is universal, in addition to all streaming services such as Tidal, Qobuz, Deezer, Spotify...etc. etc., accepts DSD and flacks from a computer or any other network storage. Allows you to completely abandon USB and all its problems, All settings are carried out simply and conveniently. Such equipment is now either not produced or it is very expensive. This amplifier was an order of magnitude ahead of time at the time of its release. And now, as we see everything digital around, and it is actually not outdated.

Hey! Just wondering if you found any more options that fit your requirements?
It's baffling to see manufacturers offer amplifiers with alleged "sub outs" without making it clear if you can set a crossover or if just sends the full signal to speakers and subs.

Nope. If you are willing to pay double my budget there are some options.
Usually looking at the manual will make that clear one way or the other....

When was the last time you had access to a manual at the dealer/shop or at an ecommerce site?
