So I got a half dozen surplus 180W class D amps from Anaview.
These are the bigger version of the 100W class D amphion uses in their amps.
I'll put up some pics of my build later, but I'm listening now.
Having 180W really does change the attack of some speakers. The NS10s seem to sound a little less tubby for sure.

Whoa, so I built all the cables I needed to install this permanently in the studio and I swear it makes NS10s listenable.
I think I'll build up a few of these and put them in the classifieds.

These should be a lot better than the Amphion amps. The 100 W one is underpowered junk. Amphion tweeters blow all the time due to the crappy underpowered amps they sell them with that people use them with. All the bundles are hilarious. You need about 1000w of class d or a beefy 300-500 class ab amp to get them to open up and make sure that only user error, not faulty or inadequate equipment, can blow the drivers. Class D modules can’t hit their advertised wattages without horrifically distorting if you look at the spec sheets. They only get halfway to 2/3rds there.
The later NS10m models with the fixed tweeter were always listenable boundary loaded or on a huge console or desk. People just used underpowered amps or awful, etched amps like Brystons. Ran off a Yamaha Natural Sound amp or Adcom, they were okay when not pushed. Avoid the Avantone CLA-endorsed Chinese clone though. That thing sucks. The tweeter is beyond awful. The QSC MX and RMX class ab output stage amps are tanks for small speakers too.

Interesting...I have some PMC TB2+ and they need an amp. PMC made an amp that hooked on the back of these speakers to make them active, but I cannot find any since they've been discontinued. I'll PM you Svart

Never did any kind of side-by-side comparison though, but I never really got along with the Amphion speaker sound to begin with, so there was never a reason to try the amps alone. I will say that these 180W amps make my NS10s sound better than the gainclones (70W A/B) or an older 100W pioneer receiver, which isn't likely from overall better performance, just better transient response from higher instantaneous wattage. I do have a high-end Yamaha receiver with the pure-path tech. It's pretty outstanding. Maybe I'll drag the amps into my listening area and see how they compare. I don't know what era my NS10 tweets are from, but they are ear-wrecking for the most part. I rarely listen beyond about 75-80dB, but for NS10's that's a few dB away from bleeding eardrums anyway! |

Do your tweets have the foam surround on the inside of the cage or are they just domed with nothing behind them? I like the ones with the foam but I’ve occasionally swapped them for the originals for some engineers who were used to the old ones. |

I'll check tonight but I don't remember seeing any kind of foam like the pictures I just pulled up on google. I believe they are without foam, but I'll make sure. |

Agreed about Amphion. I was just pointing out the reason they often blow out is the underpowered amps they’re sold with. That’s in addition to the passive crossover being unstable in them. Well there’s more current and clean headroom. The warmer, beefier, and punchier the amp, the better NS10m sound. |

The “Studio” ones from the 90s I bought used over a decade ago were much better but still honky NS10s before they blew. |

Honkey sure. Still serve their purpose for me though. And honestly they’ve never hurt my ears, but I’m not going around blasting them.
Listening at a moderate level paired with a McIntosh 2105 they are perfect for setting vocal and snare drum levels for me. To each their own.
I also really dig the NS-4’s I have too.

I do notice that the closer I sit, the worse the fatigue is. If I'm sitting back 5+ feet or further, or in another room, they sound a whole lot less ear-splitting. |

Well, I was able to find 4 more amp modules over the weekend, so I can build 2 more units.

So I had a long weekend and I was digging through the boxes of supplies looking for stuff and came across three more of these units half built. I knew I had them but I never really felt compelled to finish them until now. I need the space, lol.
So three are up for sale.
