SimAudio Moon North Collection

Anyone thinking about buying an amp from the North Collection?

I heard the 860A v1 and enjoyed it. With the new lineup there will be a some 860A v2’s coming up for sale. I am considering the older models and the North Collection. The 860A v1 was surprising good even with the sort of hot Paradigm Persona I demoed it with.

I was thinking at one time of buying 2 Benchmark AHB2 monos to drive the not so difficult to drive and slightly warm Yamaha NS5000’s. A neutral amp like the AHB2 would be great (I owned the AHB2 before) however, I think the 12-inch woofers will unfortunately not be best served by AHB2.

I am using my CODA #16 with the NS5000 right now and I can see where lots of power makes those woofers shine. So I am looking for another amp that is a bit more neutral to use with the NS5000. I can then move the CODA #16 to my Magnepan LRS+. I put these together temporarily in my office to keep the amp safe from my guests (kids). Unfortunately, I love this combo too much now to break it apart.

I am looking for some powerful and neutral sounding amps for the NS5000. I read up on the Classe Delta but that fan is a bit of a deterrent. I am testing out a Class D Peachtree GAN400 with it but it does not have that great bass like the CODA #16. Class D so far has not impressed me on the bottom end as Class A and AB amps I have owned.

So as of now, the SimAudio gear seems like to the top of the heap, and the price is already a bit over what I want to spend. I will just have to work a little longer.

Any other amps with a neutral signature that I should consider?

My preamps are Benchmark LA4 and Holo Serene. The LA4 will stay with the NS5000 system. Both do not seem to add to the signal. 


I'm certainly interested in the new moon north series. Jay at Jay audio lab seemed to love them at munich. Has anybody heard them yet. I would be looking at the 70 p series 

I thought they have not been released yet. The LA dealer that I bought some speakers from will call my in Oct when they come into the shop.

There will be a few older models in the used market soon.


I have an 860A V2....I've been very happy.  The North Collection will hopefullly resulted in some hitting the market for me to grab it and run them in mono mode!

@overthemoon  Shelleys in Woodland Hills CA, my local dealer is trying to sell their demo 860A V2. They have a 861 coming in.

As good as the 860 a v2 is the North collection is way better, with the new MDCA circuitry It's a whole new ball game on a whole different level, I'm going to be upgrading my w-8 to the 861 I'm sure I'll be shocked at how much better it will be.

@magnuman I just listened to the 791 in my house versus my was a significant change and I'm going to get the 791.

And given the sound I won't be looking to move the 860A v2 to monoblocks.  The sound stage, depth, texture and dynamics were a significantly upgraded with the upgrade of the source.
