  1. ... maybe I have not expressed it correctly - what I meant was that if a DSP update is necessary it will be done as one part of the T+A firmware update. i.e. The DSP firmware is included in the firmware update file. After updating its own firmware the main controller will check if the DSP firmware from the update file is newer than the installed DSP firmware and if so it will update the DSP.
  2. The DSP processing has never been changed. See my post above:
  3. @sbenyo is correct with his assumption that the update of the DSP software is part of the T+A firmware update. But: A) Regarding the DSP update: 1.) The DSP is not in the signal path for DSD signals. So the DSD performance of the DAC8DSD is not affected in any way by the DSP software. 2.) DSP is only for upsampling PCM signals (all incoming PCM is upsampled to 352.8 / 384 kSps. 3.) The 4 upsampling algorithms (FIR short, FIR long, Bezier polnominal interpolation, Bezier/IIR) are unchanged since production start. So there is no reason and no need to do a firmware
  4. Dear Gavin, regarding your observations I would like to give a few addiitonal hints and clarifications: Re1: This is true. I know, that T+A is constantly monitoring the progress of the new Amanero firmware. As soon as this new firmware is mature and found to be working without any glitches with Windows and Linux, I am sure that T+A will release a new USB receiver firmware for the DAC8DSD. Up to now there are still some issues with the new Amanero firmware which keep T+A from releasing a new "T+A approved" firmware. Re.2: If you update your USB receiver firmware to the l
  5. 2006be11 is currently only available as original Amanero firmware (with Amanero VID/PID numbers). To use this firmware with Windows you need to use the Amanero Windows driver - the driver from the T+A website will only work with firmware having a T+A VID/PID. Using the Amanero driver 2006be11 should work with Windows and Linux - but I have not done extensive testing. So maybe other users can post some of their experience ? I will do some testing as soon as I find the time - I will then report my findings.
  6. Just to say it again: this device is NOT intended to serve as a universal DAC. It was not designed to be combined with Amps or active speakers. It is a DAC + Headphone Amp with the sole aim to drive headphones - and to do this without compromise at the highest possible quality level. Someone looking for a standard DAC with standard line outputs should better look for something different. For someone looking for a high quality Headphone Amp with a superb DAC section might find that this device is exactly what he needs.... If the majority of forum members feel
  7. HDMI is mainly intended as an option to connect DVD-A and SACD capable BluRay players. HDMI-ARC is just an additional feature of the HDMI receiver at no extra cost - so why not make it available ?
  8. In 'NOS' PCM mode digital input data is directly fed to the converter stages of the DACs. External oversampling (in the DSP in front of the DAC chips) and internal oversampling filters in the DACs are bypassed. In this way it is possible to directly feed the DACs with externally oversampled signals at 768 kSps and use an external oversampling of choice.
  9. It is possible to use the XLR out on the front panel as a pre-out. It is a very high quality analog out with 8 Ohms output resistance only - perfect for driving long cables to active speakers.
  10. Well, network streaming is not built in - but we have a USB power output jack delivering 5A/1A continous, 2A peak which could be used for a tiny ethernet to USB bridge or NAA.
  11. Well, in fact the three headphone outputs are all analog...😉 But don't get it wrong: This device is not intended to be a standard DAC with standard line or pre-amp outputs. It was designed as a no-compromise Headphone DAC - purely and solely with the aim to get the best out of the very best headphones. Who is looking for a DAC with XLR/RCA outputs to drive amplifiers/pre-amps will be better off with a DAC8DSD which has many of the features in common with the HA 200 but intended to drive amplifiers.
  12. This device is a dedicated headphone amp - so sorry, no pre-amp output on this device.
  13. Here is some information on the new T+A HA 200 DAC / Headphone Amp combo: https://www.ta-hifi.de/en/headphones/headphone-amplifier/ Key features; PCM up to 768/32 with selectable upsampling algorithms including time-domain optimized "Bezier" upsampling additional: 2 selectable NOS (non oversampling) DAC functions : NOS DAC with analog filtering and "pure" NOS DAC with wide analog bandwidth - the latter intended for high sample rate PCM (fs >= 96kHz) True 1-Bit DSD DAC up to DSD1024 native DSD up to DSD1024 from Windows and Linux sources
  14. ... I forgot to mention: DSD up to DSD256 is also possible with DoP. Maybe this information is useful for users with Non-Windows or Non-latest-Linux source devices.
