    The Phono section will work with any MC cart. and has on the fly adjustable loading that you can change from the front panel or the remote control. Sounds great.
    C47, C52 and C2600 have been designed to eliminate add on boxes so you may be very happy with the C47.

    Thanks, Ron-C

    I thought I'd update this with a tidbit for anybody still lamenting over being unable to use Native DSD with their setups and the C47. I've started using a Sonore MicroRendu with my C47, a purpose-built mini computer about the size of a deck of cards with an ethernet port on one end and USB port on the other. Using this device to stream music from my server (I use it as an endpoint for Roon labs, but it also supports DLNA/squeezebox/etc), I'm able to play all formats natively with no DoP/conversion/etc.

    I bought it just for the convenience of not needing to connect a computer or laptop, but realized this is an additional benefit and recalled this thread.

    DSD256 with ASIO on windows is pretty tempermental. In fact all native DSD formats are. DOP is way more stable.

    HQPlayer will play one song converted to DSD256 and then is done and requires a restart. Roon is better, it works but has clicks and pops.

    When doing DOP on ASIO there are more clicks and pops on track change compared to DOP on WASAPI. So McIntosh still has some fixing to do either in firmware or in the ASIO drivers.

    This is disappointing to hear. I have a C48 and was thinking of "upgrading" to the C47 as I have a lot of DSD files. I play my DSDs currently out of my Sony HAPZ1 to an Auralic Vega. I was hoping to eliminate the Vega when going to the C47. Sounds like I will stay with my current setup.

    I've sent a support request off through McIntosh's web site.

    I mention the missing 100 milliseconds or so of a song on album startup or sample rate change. The completely unstable and unusable ASIO driver when using HQPlayer and to some lesser degree Roon.

    I've mentioned that I have no intentions of using JRiver so the standard response of JRiver works isn't really acceptable to me. Having to use a .500 second delay on sample rate change even in JRiver should be a clear indication that there is an issue.

    I have tried many media players, and I find J River is the easiest to use, most logical and intuitive of them all, has great support if you do not understand how something works or how to set it up....
    If you insist on using DSD you just have to accept options may be limited with certain brands, and some may not work that well.....whats wrong with FLAC, .WAV etc etc....
    Or whats wrong with using a media player that McIntosh recommends which actually works, and they can offer support with, RonC is always lurking here and selflessly gives advice based on his experience demoing McInotsh and working with customer support?
    Why the disdain for J River? As a professional Audio engineer, I find J River a step above the rest, its simple, no fuss, and most of all it just works?
    Isn't that what we all want? Simple solutions that just work?

    3 Reasons I don't want to be forced to use JRiver:

    1) HQPlayer with it's poly-sinc filters and upsampling to DSD sounds spectacular and far superior to JRiver.
    2) Roon visual interface and rich metadata is far superior to JRiver and it can control HQPlayer. I have a rather large collection of digital albums around 12,000 or so, the Roon metadata is spectacular.
    3) Jim Hillegass


    I've ordered a SMS-200 to use in NAA mode hopefully linux works better with the C47. If not I'll start look at other DACs for music and leave the DAC in the C47 for TV, gaming etc.

    I used to use my Linux based Roon core as my endpoint as well and didn't observe any peculiarities with sample rate changes. The C47 doesn't chirp or click when it changes resolutions like other DACs I've used.

    I will say though it would be very hard for me to perceive a half second delay unless I was listening to contiguous music, which wouldn't involve a sample rate change to begin with.

    My issue with JRiver and programs like it is I'd either need to connect a laptop to my system or remote desktop to a computer I kept connected to my system. IMO, this is just a bit of a messy way of doing things. I'd much rather use some form of dedicated bridge, be it a Sonos, Roon endpoint, Raspberry Pi, etc (I've used all with great results).

    Note this has nothing to do with sound quality, only workflow.

    I use my old 2010 MacBook Pro with a 3tb SSD in it as my music computer, just sits next to the turntable, I use it for streaming my radio stations etc because I live rural and I cant get any radio stations on my tuner in my area....
    Then I use Remotix on the iPad which is a very smooth remote desktop app......job done....

    This is basically what I did for several years. To be honest I didn't have much of a problem with it until I got a Sonos (so it was easier for my wife to use) and understood how much easier it all gets. It's good there are so many options for how to do this that suits various needs.

    At this point, I find Roon so fantastic I can't even remember what it was like before I started using it. People complain about its price; I'd pay more if they asked.

    Yeah I guess its whatever is convenient and whatever you're into.
    I just use what I have, for me personally I am completely happy with my setup, I have other interests I like to sink all my money into so the desire to get into anything else as far as music servers go just isn't on my radar....

    That's not to say I don't look at what other people are doing....It's pretty interesting looking at other setups...

    I've been in contact with SOTM already and if it doesn't work when I get my sMS-200 they will make it work. I still haven't heard back from McIntosh, odd that they simply don't care. At least offer to help the software developers work around the issue. A little disheartening.

    It might be that I've watched the Roon team work with their clients and my expectations have gotten too high.

    Got the sMS-200 and it doesn't see the native DSD capabilities in the C47. Sigh!

    If you must have native DSD, I'd return it and get a micro rendu.

    I love the build quality of the SMS-200. I'll give them more time to figure it out. The microRendu and dietPI distro both work properly with native DSD. Certainly they can reverse engineer the dietPI distro.

    It has not been my experience that DietPi works with native DSD. In fact, I've had problems with it and DSD, weird volume issues. I might give a later version a try as I enjoy tinkering with rPis, but with the rendu I suppose it doesn't much matter for me.

    I've seen a reference on the Roon forums that Native DSD was working with DietPi and C2600.
