Amp and Preamp recommendations for Yamaha NS5000


Currently have SOTM 200 ultra -> denafrips terminator +dsp board -> Audio gd he9 pre amp -> dual bryston 4bsst -> NS5000.
I am loving the sound... just sounds incredible. But wonder about amp and pre amp upgrades down the road. Any thoughts on what might work well? These speakers are 87 db efficient.
So far thinking all pass labs amps + pre.

Ok with buying used. Would like to keep things under $20k if I can. Thanks.

Just finished reading a lot about those Yammy speakers.

 12” woofer, that’s,not really a bookshelf,but a wicked badas* speaker for stands as shown! Congrats, they are a,wicked,speaker!!
  I heard the ns-555 , loved them, I’m sure these 5000’s are so much better!   
Please keep us informed .......
would love to hear the review of your experience with the speakers!
@arctikdeth What is unique about that 12' woofer is that it is made from the same material as the tweeter and mid-range. I don't think anyone else making a box speaker can make that claim. I could hear the benefit of the 3 drivers made of the same material. Not saying this is the best speaker I have heard but it is right up there.
@yyzsantabarbara 

they look amazing.
had an old pair of altec Lansing m-510’s w the diaphragm mid and tweeter. Sounded great, but the bass was lacking! Returned them,now I wish I had kept them, nice wood veneer finish, great sound 

miss them! Would sound great w my 2nd kismet system.

the yammys look wicked!
should have wicked sound from the 12” woofer.and matching mid & tweeter.

please post a review when you have time!

Yes I can say the ns5000 is a true dark horse speaker. Not a lot of people know about it but its truly magical sounding. Astounding clarity, imaging, soundstage. It simply sounds so natural. My review has more details but I love them.

As for the ns3000 ya i agree they might be a bit small for my room unless I paired them with my dual 18 inch psa lol. But I like the ns5000 integration with my psa which I cross at 40 hz and turn them down.

As for amps. People on my discord tell me a pass labs xa25 would be more than enough for my speakers since my room isn’t that big. They are 88db and I am confused because even pass said that since the specs mention 200 watts to 600 watts that 200 at least would be ideal? Does more power allow for a more dynamic effortless sound? I rather go for an x250.8 that is being sold locally imo. I’m not confident 25 watts per channel would work.
25 watts would be a joke!

 Your used to 300.
stay with it.
no less than 300WPC.

have faith!
