Best amp combo for new Magnepan LRS+ speakers?

[Fred Quinn]

Very pleased with the Christmas present from my wife. A level of detail and openness that is impressive!
Now looking for some help on getting the most from the equipment I already have.
How can I best use some combo of two integrated amps (NAD 3150 and Rotel RA-870bx) and one NAD 2150 amp to power the pair of 4-ohm Magnepan LRS+ speakers AND a NHT powered subwoofer.
The subwoofer amp would normally allow me to attach the main speakers to it, but it says not if they’re less than 8-ohms. I also found that running the main speakers thru the NHT amp hurt the sound quality.
Ideally, I’d like to use just the two NAD items; amp and integrated amp. Thanks.

Not familiar with your NADs. Check out their manuals, if they have any warnings about 4 ohm loads.

Try without Subwoofer to start. I don't know how to advise on how to integrate your sub. If it advises against 4 ohm speakers.

Maybe the 2150 is a power Amp? When you try it out, check the Amp periodically, it doesn't get hotter than normal.

Enjoy your new speakers.

I have 1.7i Maggie's. I power with Bryston BP20 preamp and 3B NRB power Amp.
I have used Rogue Cronus Magnum tube integrated @ 100 wpc.

Of the two, I would try the Rotel first. It's rated for 4-ohm speakers and 80 watts. I would also try the NAD, you may like it better.

Had the LRS, and have Magnepan 1.7i now.

I ran the original LRS with 25 and 50 watt tube amps. Just be careful with the volume controls.

FWIW, I have run some big towers on small amps, just be careful (and smart). They may not play loud, but they may play sweet.

Enjoy those speakers!
