Hi all, I have had the fortune to test a large number of drivers and horns over the years. There are of course many very good combinations with new being added all the time, but its just about time and money "find" to the perfect combination. Some experience and knowledge also comes into...

Hi dualzmak, I do understand the gain issue and have discussed with member "beatelund", who is also very helpful. He also seem to come to +5db difference between the Okto and BSS, so that seems reasonable. I have adopted you latency of 1.23ms and that sound good on a quick test. I need to...

Great. Now even I understand. Thank you. A bit puzzling as that is kind of the same as I did. I fed the BSS a digital MLS signal via SPDIF and from there the internal DAC's and also Okto digital AES signal from the BSS digital output card (can chose SPDIF or AES out). I then compared to the...

Hi dualzmak, That is way above my pay-grade. I my case it is not that complicated as no USB is involved at all. My system (aktive 3-way (LCR) & 2-way system (rear) 5.2 (+ 2 subbs) = 15 channels used) uses a buildable DSP system (BSS) with the option of analogue and/or digital input and/or...

Great Michael. Thank you. Just for me to understand as I have never used a RME unit. You mention an ADC, is that a separate box or the ADC in the RME? Is the SPDIF loop-back internal in the RME or did you connect SPDIF out to in, by cable on the RME. Or was the loop-back done in a separate box...

Thanks for input. Sound like measured latency sounds reasonable with AES in som that should be fine then. Just expected lower. The latency is not really a problem as I can introduce a delay on the other DAC's which are all the same mark/model, so that should be just fine in the DSP. I prefer...

Latency and output level? Sorry if this has been covered in this massive thread, I could not find it. I did some measurements on my Okto 8ch with the latest FW (1.6). I wanted to check latency and adjust level to the rest of the system since I am using other DAC's in parallell. The Okto was...

Hi Michael, Thank you for clarifying. We can of course do both with reasonable accuracy. The only way to align the DSP curves, as you are stating, would be on the electrical output side from the DSP. -Or after the power amp. The system is full dual channel where we can have the electrical...

Thank you for the answers. I moved from passive to active XO/DSP back in 2003 and have been trying to catch up since :-) . I do have a measuring rig (HW/SW) and reasonable monitors to compare/listen. Many DSP's have passed the work shop since 2003 and it is excellent that SW & HW finally gives...

Must confess I have not read all the pages in this long thread but I have a question. In digital audio circuits the sound quality should be reasonable the same if well implemented but in DSP solutions they are not. I have tried many out board DSP's and they do not sound the same with...

I wanted to get 7.1 or 5.1 digitally from the PC to my preamp. Either as discrete SPDIF channels or as muxed in a single SPDIF. I do have a Lindy HDMI extractor and will try that to start with.

Hi all, Frequency measurements are well covered in this thread. But I do from time-to-time struggle with finding a good repeatable practice to determine time alignment and phase correction to correct in the DSP. And the order thereof. Genelec often receive good reviews and I think this not...

Hi all, Can any of these units do AC3/DTS passthrough? If not, any idea of a USB to SPDIF converter that can?

Hi all, Is there a modern version of the Oppo DVD players that can play DVD/BD discs and stream Tidal, Spotify, Netflix and others from the internet? I do have an Oppo 103, but there should be newer better video platforms. I do like their simple interface of the Oppo but it is getting a bit old...

I have no idea if it is relevant here but sometimes the more basic DSP amps does not have the fire power to implement the full DSP settings, hence the correction is truncated. This was very evident in the JBL M2 studio monitor DSP settings as the settings for the stand alone DSP from BSS and...

When using Spotify or Tidal on a PC or mobile device they both have built in volume controls. Windows also has a built volume control and maybe they are the same but presented in different places. They don't appear to be the same as I can change them separately. Many newer DAC's have built in...

Good work! Worrying that we have that amount of garbage coming out from the DAC. I thought the DAC would limit all of that but obviously not, and as @amirm pointed out, good DAC's only do their job and pass it on to the analogue side. I will make a test on my BSS DSP later in the week to see...

I did a quick check on a bunch of files including some hi rez files I bought. None gave the same amount of garbage as the DSD files. Some the 24/96 files in wav format I have bought did not shown any garbage above 20k, or at least 80db down. Using wide band amps may cause a problem for some of...

That is scary indeed. I will try to see if my system do the same. If so I will copy your suggestion to add a 20kHz XO @48db/okt.

@amirm As a result of your video and the above discussion can you please do an experiment for us. Please feed a high rez file (high sample rate >=192kHz), like in the video, that you know contain lots of above 20k noise (or whatever it is) into any decent quality high rez capable DAC and...
