Buying advice: McIntosh vs SimAudio for Integrated Amplifier/DAC.


Hello everyone,

I'm relatively new to the Hi-Fi scene, and would greatly appreciate your advice regarding my next purchase in the realm. So far I've followed a very modular approach, buying one component at a time, and have found a lot of info online and on these forums that guided me so far. But the next step is a bit tricky (and pricey) and includes a brand that I am completely new to; SimAudio's Moon.

The two products I am debating currently are the following:

1) McIntosh MA9000 ( https://www.mcintoshlabs.com/products/integrated-amplifiers/MA9000).

2) SimAudio Moon 600i v2  https://simaudio.com/en/product/600i-v2-integrated-amplifier/
+ SimAudio Moon 650D DAC ( https://simaudio.com/en/product/650d-dac-cd-transport/)

From a price point, I was surprised to find that the Mc is actually much cheaper than the SimAudio combo, which got me to a pause. I've never heard much of SimAudio as a brand, and my Audio dealer who I trust a lot swears by the SimAudio. But like everyone I've always wanted to gradually build up a complete McIntosh setup. But I'm wondering if the double Moon setup would actually yield better sounding output. I've demoed both products and they sounded slightly different to my ears, but both in it's own uniquely pleasant way, which has left me torn between them.

So I thought I ask the more experienced crowd here about the technical specs. Keeping in mind that the majority of my music listening experience is coming from a McIntosh MT5 Turntable with a modified cartridge, and an Auralic Aries G1 through Tidal and Qobuz. My dealer insisted that the Moon has a superior DAC. I'll of course be listening through Stereo through a pair of KEF R11 speakers.

Thank you very much in advance for any insight and advice, whether it's regarding the particular products, or about SimAudio as a brand vs McIntosh.

SimAudio has a 10 year warranty. Almost as good as Bryston's 20 year amp warranty. Yamaha has a 10 year speaker warranty on the new NS 5000. Long warranty period to me means confidence by the manufacturer in their gear.
I don't know anything about the depreciation rate of the two brands, I suspect that McIntosh owners tend to hold onto their gear longer because of its long history as a company, the prestige of owning that brand and its reliability. Personal preference in terms of the aesthetics likely plays a role, as well. But, again, there's no definitive answer to which is a better choice. Some people would rather drive a '57 Chevy Bel Air than an Audi A6 and that's just fine with me.
My approach to building my reference system was to build synergy, it has taken a while. Some pieces are expensive, some are not relatively speaking, however the system sounds amazing. I didn’t put much weight into depreciation rates, focused mainly on the best sounding system I could build. I don’t see a lot of SA 600i or 700i for sale, I believe their owners hold on to them because they are really good components,  they don’t have a lot of bells and whistles, but what they do they do very well. Good luck on your search. 
Thank you so much guys. This has been incredibly helpful! I definitely got many answers, and all around great advice!
