The NCores will work great too.  I have a Mivera (1200AS), Nord (NC500), and a Nuprime ST-10.  They all drive the Spatial's with ease it's just different flavors.  The NCore at least with the Sparkos Op Amp is a little on the warmer side that the IcePower amp.  If your speakers also have the Hypex bass amps the NCore amps should be a good match.  I swap the amps out about every Quarter for a change of pace.

My experience was with the original NC400 that I assembled myself.

If you are considering a Mivera, consider this one.

Despite the high efficiency specs, I’ve always found Spatial M line to need real power to properly open up. The TM upgrade was an attempt to make them a bit friendlier to low power tubes, but they appear to still need real power/current. My guess is it’s probably phase/impedance swings.

I’d be surprised if the Lumina completely avoid these issues.

That said, these Luminas look awesome and I’m sure sound even better. They’re worthy of finding the “just right” amplification to bring out their best.

Couldn't agree more on the M series.  With my somewhat dated M2 Turbo's, it takes solid state or digital amps at around 200 wpc (into 4 ohms) to get things moving.  This if one wants to listen to all types of music at moderately loud levels.  As always YMMV, but that's my take.

I power my L2s with a 125 watt into 8ohm Ayre AX-5/20. I was originally concerned that the high(ish) powered amp would not sound as good as a low powered amp. In practice, however, they sound great together. I think the L2s work well with the extra juice despite the low power friendly spec.

Very interesting comments from all of you!  I will have to try some higher powered amplifier.  In the meantime I have noticed that I am able to get more dB with lower volume setting the longer the Luminas break in..  Has anyone tried Frank van Alstine amps with Spatials?

The SET 400 would probably be a great match with the Spatial's plus Frank has a 30 day money back guaranty.

50 watts at 4 ohms from a cheap $20 TPA-3116 is far more competent and musically satisfying at driving the M3ts than a low powered tube amp that costs 100x more money. Despite the Spatial M series being very efficient, low powered tube amps are far from ideal with these speakers due to impedance related issues.

I'm not sure I would agree. I have the M3TS with my 30watt VAC Avatar EL34 amp and have never had a problem. Listening to most music has me setting the volume knob about half way for vinyl and about 1/3 of the way for cd's. I do not have a huge room--perhaps therefore the sound is huge.

AVA Vision SET 120 amp with M3 Triode Masters. Frank reckons it's putting out around 50wpc into the 12 ohm load. More than enough power, sounds great to me.

Other than the VAC, what other amplifiers have you tried with your M3’s?

Congrats targa02 on your Lumina speakers, they look stunning and I have no doubt they sound incredibly outstanding!

As has already been said, it's a good idea to wait until fully broken in to make any amp changes.  I think I just discovered something about break in with my recently acquired X3s.  The bass was unpleasant at first unless I tuned the gain down.  I experimented with chair position and concluded I had been sitting in a room node causing issues so ended up with the chair 1' 10" further back, and the gain now close to max with great sounding bass.  But I just now sat in the original position and the bass is clear and clean so perhaps part of what is going on is due to break in.

I can also state that my experience with Spatial speakers is they seem to come alive and maybe even need more power than their specs would indicate.  With the M3 Triode Masters I had they sounded quite a bit better with the Mivera class D than with a 10 watt Dennis Had Inspire amp.

Sorry for my absence on the thread.  I have been traveling for work a lot and have not had much time to listen/play with the system.  The Luminas continue to break in nicely.  I think they may be most of the way there as they sound amazing.  My next step is to do some room measurements and listening tests to determine speaker placement.  I am still having problems finding my external drive connected to my Baetis server.  So frustrating.  I have read Q&A on forums and watched YouTube videos regarding finding external drives on Windows 10, but still not having any luck.  Next step is to call Baetis.

BTW, we got a new thick rug yesterday, so it will be interesting to hear what changes that will make to the room acoustics.

This is for WindChaser's question. None. I have owned my VAC amp for around 20 years. I purchased the M3s and sold my 91db Dunlavy's. I realize others have had problems with power, hence the MTM version, but I am very happy with what I have. I do use a Hsu sub, but never had a need/desire for more power. Got lucky....
