  1. Dear forum colleague, I currently have an Apple TV 4K hdmi output connected to an Atlona AT-HD570 HDMI Audio De-Embedder — which extracts and outputs an optical audio cable to a DAC/amplifier(2.0), and a hdmi video cable to a 4K HDR TV monitor. However, the AT-HD570 HDMI Audio De-Embedder does NOT support 4K and HDR video. So, I need to do the exact same thing ( and nothing else ), but now having 4K HDR video and 2.0 audio support on the extractor equipment. What product extractor would you recommend me to buy? Thanks, Marcello
  2. #Zackthedog, thanks for sharing your knowledge. I have looked the specs for both the SOtM sms-200 and the micro-Rendu -- and both seem fantastic. One point thought: My whole library ( 1099 albums as of today ) is 100% consisted of ALAC 16bit 44.1KHz files ( converted from CDs ). Apple TV outputs everything at 16 bit/48 kHz (not bit perfect and not 'CD quality' 16 bit/ 44.1 kHz). I see a very little loss of sound quality in this sample rate conversion, comparing to playing directly from a good CD player on the same amplifier + speakers system. That said, 2 questions: 1) If all files are 16bit 44.1KHz, would I experience a better sound quality with other music servers that support higher bit/sample rates? 2) A major concern: All files in the library do have a complete meta data set embedded: artist, composer, grouping, year, ALBUM COVER art etc. Both iTunes (on the PC) and tvOs (on AppleTV) work perfectly with this structured data. Will the software of these music servers understand this meta data and allow display and search on a TV set as well?
  3. I have a dilema and would appreciate some enlightenment. I currently serve my music library (ALAC 16bit 44.1kHz) at home using the following main setup: Windows 10 PC with SSD running iTunes ==> Ethernet ==> Apple TV ==> DAC Moon ==> integrated amplifier ==> B&W diamond speakers Since the Apple TVs (3 rooms) are all connected to a TV, I can visualize and control the library with the album covers on a big screen — wich is great. As a matter of fact, I am pretty happy with this setup and its output. However I keep reading that more and more “music servers” are being released in the market, some of then with very high price tags. Is there any reason I should consider buying a “music server”??
  4. As a conclusion for this issue, I finally purchased the Atlona AT-HD 570 HDMI Audio de-embedder -- and it worked perfectly to connect the audio from the new Apple TV 4th gen to a DAC via optical cable. I have been using this setup for a few weeks, and it sounds great. Thanks specially to Richard (REShaman )for the tip. Best, Marcello.
  5. Thank you all for the answers. It seems unanimous that a HDMI Switch with a Toslink output will solve the issue with the new Apple TV. However, I would like to ask which HDMI Switch to buy, since the 3 recommended models have quite a different price range: Option 1: Monoprice 105557 4x1 HDMI Switch with Toslink ($59.14) http://www.amazon.com/dp/B003L14WB8/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=2HMAW3SZ8VC6P&coliid=I1Z06DSY538RRL Option 2: Kanex Pro 4x1 HDMI Switcher with Digital & Stereo Audio ($109.95) Amazon.com: Kanex Pro 4x1 HDMI Switcher with Digital & Stereo Audio, Full HD 1080p, HDCP Compliant, 2.25 Gbps (HDSW4HF): Electronics Option3: Atlona Technologies AT-HD570 HDMI Audio De-Embedder ($279.99) http://www.amazon.com/Atlona-Technologies-AT-HD570-Audio--Embedder/dp/B00QFPVMVA/ref=sr_1_2?ie=UTF8&qid=1441981133&sr=8-2&keywords=Atlona+HDMI+Audio+De-Embedder Which one shall I buy? Is it worthy to spend more money for a better result in this case?
  6. Well, I believe I need to split the HDMI signal in separate video and audio. So, if I connect: Apple TV 4th gen ==> HDMI output cable ==> 4x1 HDMI Switch ==> 2 cables out: 1) HDMI cable to TV ( video ) 2) optical cable to DAC ( audio ) So, will the 4x1 HDMI® Switch separate correctly the audio and video from the HDMI input?
  7. Why upgrade? During the last 10 years I have built a collection in iTunes of around 1000 CDs burned in ALAC 16/44.1 with complete meta data including cover artwork. The new Apple TV provides a huge improvement in the interface with this meta data: screen, remote and even voice recognition. So, I will be able to search and experience the collection in a much richer and functional way. Furthermore the current Apple TV (3rd gen) is having problems displaying some cover artwork due to memory restrictions -- issue that should be solved with a hardware upgrade. Moreover, the new Apple TV has games, apps, interactive content that certainly will be cool to try with a nice audio setup.
  8. Apple just released the new 4th gen Apple TV -- and killed the optical audio output port! For some time I have been serving my ALAC 16/44.1 audio library from my home-office to the living room in the following way: iTunes (running on a Windows 7 PC) ==> Ethernet cable ==> Apple TV 3rd gen ==> optical cable audio output ==> DAC Simaudio Moon 100D ==> RCA analog audio output cable ==> Cambridge Azur 851A Integrated amplifier ==> B&W Diamond 804 speakers obs.: From the Apple TV 3rd gen I also output a HDMI cable (video only) to the TV. Well, now Apple just released the new 4th gen Apple TV -- and eliminated the optical audio output port! How I am suppose to output audio in this new 4th gen Apple TV?? There is only a HDMI output in this new model: Please help.
  9. I originally posted this thread and I am 101% glad I did it. Great info and thoughts received, no doubt. Since I received so many variables regarding the iFi iUSBPower , some positive, some slightly skeptical -- I can't seem to be able to process a purchase decision: having a Peactree decco65 and a good quality USB cable, is the iFi iUSBPower going to increase sonic performace? I will keep processing...
  10. I’ve just read the iFi iUSB Power review at HP Soundings. Thanks for the link. The device concept sounds really interesting -- in theory. - did anyone tried iFi iUSB Power in your system? did it make any relevant difference in sonic performance? - Would the iFi iUSB Power make any difference in between my PC and the Peachtree decco65? I believe decco65 DAC already works with filtering, since it is designed for PC use.
  11. DJ, I went and checked the iUSBPower you recommended: iFi-audio iUSB This is the one, correct? Never heard of such a device before... One thing I do not understand: since the USB coming out of the PC is full of noise, how can the iUSBPower "clean" the noise? Please expand on the topic. thanks.
  12. I use only one PC Windows 7 64bit as a music server: The server PC is in my home-office: PC ==> USB ==> directly connected to a Peachtree Decco65 DAC/amp => D4 Peachtree speakers. The same PC is also connected to an ethernet network, serving an Apple TV on the living room: PC => ethernet => Apple TV ==> toslink ==> Moon DAC ==> Cambridge Azur 851A => B&W 804 Diamond speakers. So I use both USB and Toslink in my home music system.
  13. I am listening CD and studio quality music files from a Win 7 64bit PC. Question 1: Since the audio data being sent is binary, what are the real advantages of a high end USB cable ( ex.Kimber Kable USB B Bus ) versus a regular USB cable? Question 2: Which digital audio connection is better: USB or Optical fiber (TOSLINK)?
  14. I assume I would connect the remote MacMini also to my TV ( by HDMI ) in order to visualize and interact with the Mac iTunes interface ( the TV will work as the monitor ). So...the iTunes on the Mac will behave functionally the same way as an Apple TV interface? When you say that: "the remote library is basically in "read-only" mode on the local machine". So Just like on Apple TV, I can NOT add/edit music from the server Win 7 PC. But can I: select across my playlists? do a search by keyword? ( e.g Miles Davis ). Browse by category? etc. The question is how much will iTunes be functionally limited on the remote MacMini?
