  1. Hallo Jussy, Many thanks for your quick reply. You mean send 705.6/768k PCM there in DOP = max 256 DSD . Instead of DIRECT DSD due to the fact I have an iMac. Right? Best regards, Andreas
  2. Hallo Jussy, If running at DSD256 in DSD Direct mode the DAC cannot be used as Pre-Amp ? Is that correct or do misinterpret your post and the bulky manual too? How do you rank the RME ADI- 2 on your own stereo installation ? This compared with the list showed on yr web-page? What is money wise a good DSD DAC in terms of SQ?

    Hi Jussy, Many thanks for your extensive and very meaningful explanation. I have learned a lot.

    HQ Player

    Dear Jussi, I have two questions for upgrading my HQ-player system to handle DSD256 at least and preferably DSD512. I am using now a stand-alone headless Mac Mini I5 (2,6 GHz; late 2014) with 8GB memory for HQ-Player. I also have a Mac Mini I7 (2.3 GHz; late 2012) with 16 GB memory. At this moment I use an Allo UsBridge as NAA (based on DietPi 6.6) as input for my Teac UD 501 (Max. DSD 128). Do have the Mac Mini’s sufficient horsepower to use HQ-player with a new DSD DAC like Project ProJect Pre-Box S2 Digital? And if I decide to spent “some” more money the Chord QUTEST or the new TEAC UD 505? Is it possible to use on iMac (OS High Sierra) the DOP upscaling possibility to handle DSD 512 or is this limited nowadays to DSD 256?Ps. I am not sure if Native DSD is possible at all? And which SDM-filters can than be used for such an Apple config? If present Mac Mini don’t give the needed horsepower what are the minimum requirements within the Apple IMac IMac <=> Mini range? Please your advice. Very best regards Andreas
  5. Dear John, What happens if you don't use the AC safety ground in a wall outlet. The "third pin" so called the "earth" connection. Does dis help avoiding / help avoiding leakage? This very often the case in Europe especially the Netherlands. Not all houses or rooms especially on the upper floors do have an earth connection. . Ps. The polarity of the + / - poles has been checked/ changed by minimizing its residual ground currents. Very best regards,

    Allo Sparky USBridge

    Just like the previous times a meaningless answer. Read the mails from me and many others better. Be ashamed of Allo & DietPi for this clumsy behavior.

    Allo Sparky USBridge

    Dear @rahul_kc That's really outdated information. There is no instruction how to update from older versions ! Namely that you have to re-flash to V 6.0 due to the fact that a system update from v159 and older isn't not possible at all. Ps,. The Webpages/ links last updated by Fourdee dated 30-09-2017 etc... Stated recently on HQplayer Network Audio Adapter forum and referring to my earlier posts /questions to Allo. IMO Allo is extremely slow, very reluctant to give help or respond to customer questions on this CA forum and Roon Community. The support and software is too cumbersome and responsiveness a way too slow. The software is too much tinkering and certainly not customer-friendly. This is also due to the multitude of updates that I have had to install during the last 3-4 months. Started with version 156 and already on 6.4. These successive updates were certainly not error-free and hardly doable for non Linux experts. In addition, it all takes up too much time that you can use better to listen to music than to find out how to re-flash and install an EMMC card. In addition, the current documentation is absolutely inadequate. That is a missed opportunity and makes it less fun that the aforementioned childhood diseases have not yet been adequately remedied. Come on Allo this can be many times better........ Despite my complaints, the Allo UsBridge is a great device when it is finally set up properly. And it gives a very good USB signal in combination with the Uptone Regen and a Sbooster LPS together with the standard SMPS.

    Jumper 28 & USB question

    Recent post from All says; From the manual : 1. Jumper on = feed power to DC convertor on Usbridge (and will feed both Sparky and Usbridge) or feed power to uUSB on sparky and it will do the same thing 2. Jumper off = you can feed power to USbridge (dc connector) and it will feed Sparky , but if you feed sparky only it will NOT feed the USBridge hat. Of course you can feed both sparky and usbridge independently . I guess there is a diode right there that gives the direction on the positive ..
  9. @volpone @Allander Please see my message to Allo.Com last week. And several posts before on the Allo Club pages. IMO Allo is extremely slow, very reluctant to give help or respond to customer questions on this CA forum and Roon Community too Now all is too cumbersome, too much tinkering and certainly not customer-friendly. This is also due to the multitude of updates that I have had to install during the last 3-4 months. Started with version 156 and already on 6.4. Ps. This install and also the different versions were certainly not error-free and hardly doable for a non Linux expert like me. In addition, it all takes up too much time that you can use better to listen to music than to find out how to re-flash and install an EMMC card. In addition, the current documentation is absolutely inadequate for a novice.That is a missed opportunity and makes it less fun that the aforementioned childhood diseases have not yet been adequately remedied. Despite my complaints, the Allo UsBridge is a great device when it is finally set up properly. And it gives a very good USB signal. This in combination with the Uptone Regen and Sbooster LPS together with the standard SMPS. Posted Wednesday at 01:51 PM Dear ALLO & DietPi-Team, I still have problems with connecting ALLO UsBridge and my DAC Teac UD 501. Despite that in Audio (via dietpi-config) 2.0USB is set. When I switch on my DAC in advance, the default 44.1 or 48.0 kHz is set despite my DAC can handle PCM 384 or DSD 128 . Ps. Allo previously advised to start the DAC first and then the Allo UsBridge (& Sparky). Why does not it work flawlessly? My suspicion is that the startup sequence Sparky <=> UsBridge is critical. When I started the Bridge first and then the Sparky a few seconds later. And during this start-up, the DAC also starts up in 60% of the cases. Conversely, first UsBridge and then Sparky gives ..... a somewhat worse result? Ps. the later start of the DAC does not work either. My preliminary conclusion is that if I do not start everything more or less at the same sequence it will not work properly. And that is pretty boring and I have to restart everything again. Is there also a rescan done by DietPi? Why is the DAC preceded by the start-up routine before and after the start seen as standard DAC (=44.1 and 48.0)? Would you please sort this out thoroughly? Many thanks in advance. I use a TEAC UD 501 DAC / Mac OS 10.13.3, HQ-player 3.20.4 and DietPi Standard Version 6.4 without Web Gui. In my chain I also Use the Uptone Regen to improve the signal. Ps. And I use 2x separate Power Supplies (Sbooster 5v,1.5 amp for the UsBridge and IFO (SMPS) Ifi-Power (5V/2.5A) for Sparky .
  10. Hallo Jussy/ Miska, @Miska Possibly a misunderstanding or a lack of knowledge on my part. I have asked you on 09-02-2018 if the HQ-player (original) NAA distro/package is working on an Allo UsBridge? As you can see in attached file you have said no. The same answer by Allo. Now you state that a 32-bit armf you build " for ages " will work on the Allo Sparky resp. UsBridge hardware? I am lost! Please advice / explanation what I have misunderstood. Very best regards.
  11. Dear Jussi, Thanks for your reply. It's a pity that HQ-player NAA software doesn't work resp. is available for this very nice ethernet device called Allo UsBridge (+ Sparky). For me is the understanding / programming of DietPI to difficult and too time-consuming . And it has so many features which I really don't need. Only HQ Player NAA-functionality with or without Roon add-ons=>>> I like to keep it KISS. Best regards,
  12. Hi Jussy, Just have read on FACEBOOK you released an ARM 64 distro for NAA. Does this work on a Allo Sparky respectively UsBridge too? Due to the fact the Sparky uses an ARM Cortex A9 Quad Core Processor at 1.1GHz. Thanks for yr response in advance.
