Choose between McIntosh MA9000 used vs MA8950 new

I am a 8950 owner, and there's already a lot good opinion above,

• 200w rms, 400we Peak.
• New in condition
• Come with DA2
• Etc

Since you use 805 d4 I would say go for 8950, and I have some different experience to share with you.

Somebody already said that, you might underestimate the da2. And also, if you really enjoy the ''mac sound'', you might want to just use the DA2. It's the best sync.

I have done a blinded test between DA2 and ps audio nuwave dac(non dsd version). 4 out of 5 guys pointed correct wich is pure mac and which is ps with mac.

I have changed the power cap in the nuwave dac, and that makes my ps dac mac sounding like. The only guy make mistake is the only mac owner and he said he made a oppsite choice because it sounds ''too mac'' to him

I have spent considerable time with this amp and would be proud to own one. In no way is this amp going to be the bottleneck or limiting factor of any system that most would assemble. It’s a strong argument for not having to buy separates. It’s that good. Plus you can always add an Amp. Yes the DAC card is that good.

Have owned a MA8950 for 2 years and streaming via a Bluesound Node 2i.  I’ve listened to many systems and I’m always amazed at how good my system sounds.  I think the DA2 module IS underrated.  You’ll love this amp.  If you had a chance to own a 9500 or a 12000, then you’d have more of a good thing but you dont need it unless you got the cash and the supporting equipment to take things to those higher levels. 

Thanks to all your inputs, which make me rethink my set up plan. I just got hold of a preowned c53, which has the da2 dac, similar to a 9500. I hooked up to an amp and digital in to its da2, the sound  is phenomenal! Now I see a good dac is very important.

The 8950 has the same DA2 dac module as the 9500 and the C53.  Not to dissuade you from where you are heading with separates.
