    The latency would become too excessive after a few million taps at 768kHz for a LP filter. It is probably for DSD only that runs at MHz speed. Have you tried it?

    Audeze LCD-24 LIMITED EDITION - now including impressions and comparisons

    I have had the 4 for more than 2 years now, I have only demoed the 4z briefly. I didn't think there was a big difference either, for me it was more in the sound stage, the 4 is more 3D/holographic. You need to find something that works for you what ever that may be, some things just click and...

    Audeze LCD-24 LIMITED EDITION - now including impressions and comparisons

    I just watched meta571's latest Q&A #12, he currently has the 4, 4z, and 24. He said his fave of all headphones he has ever heard is the 4 (eq'd) and that he probably won't do a review of the 4z or 24 as he doesn't like them. I had a 2014 LCD3F which was magical and the drivers were changed in...

    Hugo TT 2 by Chord Electronics - The Official Thread

    That 1% for headphones just happens to be some of the best headphones in the world. For speakers it probably can't drive 99% of them. That is a pity because for a top class system you will probably need an amp. The TT2 as good as it may be is not in the same league. "Dave DX" could combine the...

    Audeze LCD-24 LIMITED EDITION - now including impressions and comparisons

    The article below has a bit of an explanation and has a diagram showing the structures. There is only 60 grams difference between the 4z and the 24 which is a more fair comparison since only the magnets differ(?). Interesting also, the 4z is more sensitive than the 24 (98 to 96dB/mW) but the 24...

    Audeze LCD-4

    Da Funk by Daft Punk, the bass in this song is so powerful on the LCD4 yet so clean and controlled. It amazes me every time I listen how it can possibly do this without self destructing.

    An excellent presentation by Rob, I watch them all but somehow I missed this one. Also, this is very interesting about hearing and correlates with what Rob has been saying.

    This diagram might help to understand sinc interpolation. Figure 1 shows what a sinc function looks like. It can be calculated from the formula shown. Note that the peak value equals 1 and it continues to plus and minus infinity time and never completely decays to zero. It is scaled so that the...

    It doesn't have to be real time, you can do a 256 million tap filter today with a little conversion utility that could be done with a few a hundred lines of code. It will still be 768kHz regardless of taps, smaller than DSD files, and it won't have any latency due to the FIR when played. You can...

    Hugo TT 2 by Chord Electronics - The Official Thread

    If I remember correctly, people were asking Oppo for a balanced cable so Oppo made one. Some amps work better balanced like the Headamp GSXmk2 so they wanted to use balanced. Balanced or not makes no difference, just don't turn it up if the amp has more power than the hp can handle.

    Sure, if you stop at 105dB and not 115dB. Not saying it can or can't run certain headphones, pointing out the differences for low/high impedance case and why it may matter by using an example. Sadly, it sounded utter balls with all my headphones so it was gone quick. This is off topic anyway...

    The HD800 is 300 Ohms, never tried it on the Mojo, so don't know how it sounds...but... Its a problem at both ends, low impedance you get current limiting and high impedance you get voltage limiting. Ever noticed how almost all portable headphones have low impedances, it's so they will work...

    What goes down the cable will be lot higher than 384kHz. 384.4kHz x 32bits = 12.3Mbps per channel. So you want a ferrite that targets the 2GHz range and stays away from 12MHz, the HF ones look best. Edit: For the mscaler it runs at 768kHz per BNC cable so double that above.

    Audeze LCD-4z - Impressions Thread

    Hmm.. there is a prototype mentioned in that Josh stream a few pages back. The LCD24? It had the same shell as the 4z tho. The 4z is an improvement but still awkward, time for an all new design. BTW, Google conversion is cm to feet so 5.7 feet (not feet and inches).

    Yes for the ideal sinc FIR case... with long tap length, 1M taps, you have to wait for half the samples because it looks into the future, so 500k samples which is too long for video. IIR has no delay but no good for this case. Rob did an asymmetric FIR to reduce it, has less taps for future.

    For the mscaler, it is a sinc function as per the sampling theory, its a formula you can use to get the tap values and a window function. For other situations it is not as clear, you have to design to meet specs and resources. Like the video filter on the mscaler, it has to have low latency so...

    Lets simplify things and compare to DSD1024... You can think of the pulse array dac as a "better" DSD dac. The pulse array already runs at 2048FS, that is like DSD2048. Elements are not like bits, they are levels, going from 32e to 64e is like adding 1 more bit, so from 5 bits to 6 bits. Dave...

    Quality of taps always matters. The number of taps depends on what you are trying to do and also what is possible with the processing power available. For what the mscaler is trying to do, we need an infinite sinc tap filter ideally, so we need quality and number here.
