I agree with you. Said that if they like a piece of the DAC business and include DAC's in their amps or build a full digital preamp capable of DSD then they should make sure it's up to par with the build quality of the remaining units. By now they should have enough experience to know what they are doing.

I watched the display but in my case something else happens I played the album from America - America in 24bit/192kHz and the DSD version. The Display shows USB and then ...... When I start playing the 24bit version it shows 192kHz and the song starts as it should be. When I do the same with the DSD album I get DSD64 on the display and it disappears and then it comes back and the song starts playing with a slight delay on the first bar off the song. Doing it a view times back and forth and it seems to get the hang of it and it works. I think somewhere there is a timing issue. The should ask CEntrance to rewrite the software on the D150 as they did with some of the other products. At least those do not have any issue

I'm in San Francisco

I also find it strange that in this day and age you have to sent a unit back for a Firmware update. I would think on a fully digital unit it should be software upgradable.

Unfortunately problem still exists. I spoke with McIntosh tech support and they had no solution and said they can not replicate the issue. I also spoke with the regional manager for McIntosh and he said he will escalate it. The regional Manager came back advising me to follow the step by step guide on the website to configure my PC since they cannot replicate the problem. He said that there are so many software applications to playback media and they could not be compatible with all. I said fair enough but there are only about 3 major players used and since its a fully digital solution it should not be that difficult. When I was send back to follow the instructions on the website I told him as per our initial conversation that I have a Apple Mac mini and not a Windows PC. So there is no instructions on the website and also it seemed they not payed attention to my problem/setup. I was told they will send me instructions for a Apple setup but hat never happened. At that point I gave up bugging them and just start living with the problem. I think if there are instructions for a Apple Mac they should post them on the McIntosh website. Also as far I heard they had a similar issue before with the C48 and could not fix it and then upgraded to the C50 and had someone else write the Firmware for them. But now they did not wanna pay someone else to write the software with the D150 and again and we got the problems. I hope they can fix it with a future Firmware update

@med_designer. a question from a fellow owner. Do you got any issues with your D150? I am using a MacMini with Audirvana 2.1x. MacMini connected via USB to the D150. My D150 has Firmware 1.01. It seems due to clock issues the unit mutes the first tone of the songs. So if I play anything which does not have a silent intro the first beat is missing. Example: On Eagles - Hotel California you would miss the first tone of the guitar. Anyone else experienced this problem?

I got them hooked up to a McIntosh MA7900. Playback of Lossless Audio from a MacMini via USB connected to the DAC of the MA7900

True. But as i understand Amarra under MacOS does it for you automatically. So no need to check each track on bit rate and adjust it. I don't think JRMC does that. Also I noticed that if you catalog your library with JRMC it creates xml files and jpg files which can use up GB of space on your drive.

I would skip J River and boot camp. Windows will not change the bitrates for you. You would have to manual change in Windows the setting depending on file you would play. Since you got the Mac run iTunes and get Amarra. Amarra will switch for you automatically the bit rates and send the file pure to your DAC for best possible playback. If interested I can provide you with a coupon code to get the app @ Sonic Studio Amarra High Resolution Music Players and Professional Audio Mastering Systems for $99. Regular price is $189

I agree regarding Mac. I also have two Macbook Pro (13" Retina Late 2012 {Wife} / 15" Retina Early 2014 {Mine}) which I prefer to use. Since I conected the the XPS to a 55" Plasma I decided simply run the music from the same unit so I can use XBMC for Movies and iTunes for Music. I think I may switch to upcoming Mac Mini when released. I tried foobar2000 but I always feel like I did a time warp. Since you use the Mac Mini what software you use to play music ?

I do also have the PL300 and a question to fellow owners. The screws on the back of your speakers are not all tightened ? It seems that when I touch them I could actually unscrew them

I also have the Peachtree novaPre and had a question about it since it does not seem clear to me. I run iTunes on a Dell XPS. Music is stored in Apple Lossless Audio Codec (ALAC) either in 16bit or 24bit on a Synology DS2413+. I connected the XPS via USB Cable to the novaPre and iTunes seems to play any file i play 16bit or 24bit. Said that I noticed under Playback Devices / Peachtree 24/192 USB X / Properties / Advanced a option for default format. Right now its 16bit 44100 Hz. Do i have to change this setting every time to the bitrate of the file I play in iTunes or does the DAC in the novaPre recognise via the USB link the bit rate of the file and adjusts ? Also would you guys think running a Mac Mini as music server would be better than a Windows 8.1 based pc ?
