The McIntosh D1100 DAC and preamp has arrived! I only found one review of the D1100 online and it was in German, so thought I should give some impressions here. This is my first serious impressions/review post of audio gear, so please be kind....... generally I only review books, though I have reviewed toilet paper and Chipotle-seasoned tuna snack packs for Amazon. (The latter two turned out to be a necessary pairing).

Product details and specifications can be found here: http://www.mcintoshlabs.com/us/Prod...ails.aspx?CatId=preamplifiers&ProductId=D1100

The obligatory unboxing section of the review:

The D1100 comes in a big box. That box is secured by foam in another really big box. This thing is HEAVY (~40 pounds), so be sure to stretch and lift with your knees when unboxing!

Setup:

Setup is a breeze, if you don't look at the manual. There is also a wiring diagram on the top of the chassis. For use with a PC, you must download a USB driver from the McIntosh web page.

Unfortunately, foobar2000 does not seem to play well with the McDriver. I could not get DSD256 files to play with this combination. Also, there were annoying bursts of static when switching between files of different formats or sampling rates. Fortunately, switching to Jriver Media Center eliminated these problems.

The D1100 integrated seamlessly with Tidal.

Sounds impressions:

Setup: Windows PC > Kimber Summit 5m USB Cable Silver Plated-OFC > D1100 > Kimber Select Copper 6 Wire XLR Cable > Cavalli Liquid Gold > Axios Headphone Cable (4-Pin XLR) > Focal Utopia

My retirement account balance was hoping that this would be an end-game setup, and although it has only been a week, it may very well be. The Mc Special Sauce seems to tame the LAu, which can be unforgiving of low-quality source material. Poor pop recordings that I've ripped from CD sound listenable. High quality digital files sound excellent. The D1100 hits the perfect balance between accuracy and musicality.

I've listened to classical music infrequently since realizing in high school that I am not a very good trombone player, but I am listening to it all the time now. The D1100 is very detailed and has a wonderful dynamic range that lends itself well to instrumental recordings. Dvorak's Symphony No. 9 gives me goosebumps. Classical can be fun too: Copeland's Rodeo transports you to the Old West. (Though the whips in Buckaroo Holiday make me feel bad – poor horses. They do sound clear enough to make you jump though!)

Comparisons:

In an effort to isolate the contributions of the McDAC to the setup, I listened with a Chord Mojo in line out mode in place of the D1100. Since the Mojo doesn't have a balanced output, it was connected to the LAu via an AudioQuest Forest RCA cable. I love my Mojo, and I was perfectly happy with this setup until the McDAC came along. An improvement in sound stage is immediately noticeable. With “So What” (Miles Davis – Kind of Blue) the placement of instruments is distinct and accurate. Vocalists sound as though they are in front of you, rather than coming from inside your head.

The D1100 does have a SE headphone out, so I was concerned that its purchase would make the LAu obsolete. The balanced output of the LAu is so good that it is staying in my setup. The output straight from the D1100 to the Utopias with stock cable sounds a bit veiled by comparison. Please don't misunderstand, the headphone output of the McDAC is very, very respectable, it is just hard to go back once hearing something better. I think that someone considering purchasing the D1100 as the foundation for a system with the intention of using the headphone jack and perhaps adding an amp later would be pleased.

Conclusions:

Initially my plan was to buy a Chord DAVE. @TSAVJason mentioned the D1100 as an alternative, so I went with that, because it is just easier to do what he says. :stuck_out_tongue_winking_eye: (Just kidding. I trust his opinions). :) The reality is that most of us here don't have unlimited budgets for gear, and for me the D1100 offered more bang for the buck. I got a DAC plus TOTL interconnects and a balanced Utopia cable for what I would have paid for the DAVE.

The versatility of the McDAC was also a draw. I've had the same set of JBL floor standing speakers for 15+ years, but should I ever decide to upgrade them and my crappy Sony amp, I'll be glad to have the D1100 to build a system around.

Overall, I am ecstatic about the D1100. The blue meters are hypnotic. The nice thing about headphones is that no one will know that I am watching them while rocking out to Taylor Swift. :L3000:

Nice! Does the D1100 have a slight fade-in when starting a track after a period of silence? This is the one thing that bugs me about the MHA150, and apparently McIntosh is making a firmware update to fix it.

Different generation of DAC so no it doesn't

Glad they made that change. You wouldn't happen to know anything about McIntosh firmware updates, would you @TSAVJason?

I'm sorry, I haven't been paying attention with regard to the MHA products. All McIntosh firmware updates are available for download on their site. So if there is any that's the best place to look for it.

Taylor Swift? Really? Good review!
Haters gonna hate, hate, hate, hate, hate....... :stuck_out_tongue:

No. Initially I heard that, but then realized that the default crossfade setting in JRiver is "aggressive," so it was my bad.

Actually the current generation have the issue of a half second of the start of a song being cut off if the unit has gone into silent mode. The next issue is the major popping on playback stop when using native DSD mode and the windows ASIO driver. This makes DSD256 completely unusable. Ron @ McIntosh told me DSD256 is too much data don't do it. Sheesh!

The DSD pop isn't an issue ff doing DOP and a maximum of DSD128.

For the amount they charge for the D1100 you would think McIntosh would care, but they simply don't.

We can't duplicate your issue on any of our 4 D1100's. We've tried many different sources in DSD 256. We are unable to find any playback issues.

I've known Ron many years. He has a dry sense of humor but I doubt he would use the words you've posted here in anything other than jest.

Do the VU meters function when used purely as a Dac into a separate headphone amp?

The meters are directly connected to the line output stage. This means unless you use the volume control to get the meters moving that they otherwise don't move when in the DAC only application.

yeah Mc doesn't really care to ever fix firmware once a product is shipped. D100 has a number of volume control issues they have never acknowledged and years later it is still v1.0

That's odd because I can't find anyone that can't reproduce the issue on the C47, C52, C2600 or the D1100. They all use the same front end portion of the DAC and the same drivers.

HQPlayer or Roon configured to upsample to DSD256 will do it. They have to be configured to do Direct DSD not DOP as DSD over DOP won't show the issue.

Roon is currently suffering its own issues. I'll try HQPlayer and report my findings. We use JRiver and are not suffering any of your issues.

By the way, I spoke with Ron. He has no recollection of any call involving your described issue.

I've been working with McIntosh on a lot of projects over the years. In my experience if a dealer calls with a customer issue they get to the resolve asap. I am one of those contractors that help them in this.

So now, getting past the minutia ....are you using a PC or a Apple?
