When I've heard valve amps driving the NS-1000Ms I've always found the bass lacking a bit in 'grip' and having a different character to the rest of the frequency range - you may find quite different though and I've not heard the Yammies with a PM4.

I'll let you know this time next week
I agree with Mark; they like something good up them!
The PM4 should be a great match. I was surprised, given their quoted efficiency, how much difference extra power made. A great speaker nevertheless; truly great.
Nine times out of ten, when you've reached a moderate sensitivity level with the speakers, it's the system impedance load and how reactive it is that tends to have the greatest impact. If the amplifier can't swing sufficient current, that's where you get dynamic compression. Based on fallible memory, the NS-1000m isn't the friendliest load on the planet, but it's nothing to cause major issues either; sensitivity is lurking around the mid-high 80s, there's a ~25ohm peak around 500Hz presumably due to the electrical offset of the low-pass & the HF leg of the midrange BP. LF range has the charateristic single peak of a sealed box, again lurking around 30ohm point. There are far more unpleasent loads on the planet. If you want to drive them loud in large rooms, they'll need a big amp of course, but for more moderate sized rooms & SPLs, you should be fine with > 40w, accepting a bit of LF compression on large dynamic peaks.
Why is it that people who only listen to girl with guitar and other hi-fi noodling, quietly, in small rooms, never get that if you want Sabbath the way it was meant to be heard you are going to need more than 20 watts? And think just because the amp has no power it must intrinsically be better than one that can actually drive the speakers without clipping?
Rhetorical rant over, please drive on by.
I can only speak about audible differences because I don't understand the science. I own both amps so I have no reason to prefer one combination than another.
I think it is much as Scott outlines above. At the end of the day, irrespective of the specs, the NS-1000M is a 12" driver sealed into a box with quite a small internal volume and it has to compress that air to get the driver moving.
I usually find the exact opposite!!! People who listen to "girl with guitar and other hi-fi noodling, quietly, in small rooms" with say 30 WPC RMS or more asking me "don't you think it would sound better if I get a 100WPC amp to 'drive the speakers properly with plenty of current'?" .... NO it would make no difference as you are never using more than 2W anyway!!Quote:

I suppose to paraphrase it's surprising how little power it takes to give volumes where it's difficult to talk without raising voice/mild shouting but also surprising just how much power it takes to go up from there to "live band levels" ;)
This next will be a little controversial - but I think that often people actually like the sound of their amp as it goes into clipping (as long as it isn't too severe).
Maybe that is speaker-dependant? - Some are so stodgy-sounding that a little distortion just livens up the sound a bit. Yams would be the opposite. I'd say you want the signal as clean as possible with them.
