I have had my MA12000 for 3 yrs now. My first dip into audio was the 70s/80s, hence always leaned towards separates. I went to several listening sessions of different amps/preamps and a few integrates before my purchase. One session I had the chance of comparing the McIntosh separates to their integrated MA12000 side-by-side…done deal. They really nailed it…the tube front side with the s.s. backend done in a proprietary pathway is excellent.
The MA12000 does everything well…some exceptionally well. You would be hard pressed to find a better preamp. More connectivity than anyone would every need too. It will drive most speakers easily; never gets warm. As more of an analog guy…I decided to add a phonostage even though the MM/MC sounded really good in the MA12000; PS Audio had a discount promotion on their Stellar phonostages. It was difficult to tell the difference…the separate phonostage added a little more “depth” at the bottom end, but very little else compared the the MM/MC input on the MA12000. Again, this integrated does everything well and some exceptional well, really no weak areas except it is really heavy ( a two person lift) & big in size.
The D2 card I have not compared side by side yet with a separate Dac. I am looking for a good streamer, currently using the Bluenode which is great for what it does at the pricepoint. Last week I did a lessoning session/audition with the Aurender N20 with a Berkley Alpha 3 Dac = I found my streamer! I think my best path is to go with the Aurender streamer and use it with the MA12000/D2 & add a separate Dac down the road – if needed; D3 may be out by then? I feel the DAC world will only improve and hopefully the price-points drop…the MSB discrete has positive reviews but at 12K…I can wait. I like the company philosophies of Chord & Schitts and their Dac builds….if a decent used price comes up, may get that to compare with the D2 card.
You will be very happy with the newer McIntosh integrated!
