    Watts Up...?

    I think this is the better way I conceptualize this (which is sort of what Rob Watts has said). When you have XLR to speakers and RCA to sub, let's say you are at a specific volume where you're pumping 2V to the speakers, then you're sending 1V to the subwoofer. Now if you have RCA to speakers...

    So I actually gave this feedback to PGGB programmer when the software first came out because the apodizing filter is only applied for 44.1kHz file automatically and not for say 96kHz. So he sent me a non-apodizing version where as he showed you can just click on and off. And indeed it did solve...

    Watts Up...?

    Some desktop Intel/AMD PC motherboard chipsets support Toslink but not at all sampling frequencies. My 2013 desktop chipset only supports 44.1Khz, 48kHz and 96kHz Toslink for some reason and definitely not 88kHz. This is why for people who want to try Toslink, I usually recommend getting a new...

    CHORD ELECTRONICS DAVE

    So I have the following conjecture about why most of the time, RCA is technically superior to XLR from DAVE. If you’re driving your amp directly, let’s say listening at a volume level of -19dB via XLR so you’re putting 1V via XLR into your amp. If you’re using RCA, your volume level would be...

    CHORD ELECTRONICS DAVE

    I bought it when it was first released. I would say it's basically left on all the time since then (late 2015). Still working great and still sound fantastic.

    Watts Up...?

    Thanks for sharing the MidFi Guy YouTube video. What I learnt was that: 1) Rob Watts may have found a limit for audibility of noise floor modulation, perhaps from his ADC research which I presume he’ll share once the DAVINA ADC is ready 2) Rob Watts will talk about his WTA filter algorithm...

    I haven’t listened to TT2 at all. But having hung around this forum for a while and having brought my Mojo, Hugo 2 and DAVE to my local Head-Fi meet and seen people’s responses and how they compare it to other DACs and amps, I would say the main issue is that people listen for different things...

    CHORD ELECTRONICS DAVE

    Ah. The TV. Now it all makes sense why your dealer suggested you just buy a new system with DAC for that space. Now I'm a bit curious, if you do end up with an integrated DAC+amp in the TV room, how would you stream music to the DAC+amp? I'm not sufficiently familiar with Lumin to know what your...

    Wait. Your photo only shows 1 lithium battery. Do you have two lithium batteries, one to Lumin, one to M-Scaler? Because I thought normally, (non battery), if you power Lumin and M-Scaler with the same linear power supply, you basically take out the USB galvanic isolation between the Lumin and...

    CHORD ELECTRONICS DAVE

    I think Chord has always said that it prices its products as a multiple of the cost of manufacturing. And some manufacturers as you pointed out usually price their products at the highest price point they can based on the prices of comparable products or they estimate how many products they'll...

    Hugo M Scaler by Chord Electronics - The Official Thread

    I feel like you're overthinking this. To me, there are theoretical issues and real issues. The real issue with getting the M-Scaler is that some people can't hear the improvements. The theoretical issue are the noise issues that you talked about. I wasn't aware of these issues and I enjoyed my...

    Hugo M Scaler by Chord Electronics - The Official Thread

    Chord manuals are always extremely confusing. The sample rates under the columns Single BNC & Optical refers to the HMS Single BNC OUTPUT & Optical OUTPUT, not Input. All the questions being asked are about using a Single BNC input with SRC-DX or using the Optical input. Part of the challenge I...

    Yes. Up to 192kHz. I only feed my M-Scaler using the optical inputs.

    Okay you’re right. The new photo posted today looks like a Mojo2. Haha, I wonder if we can lure @Rob Watts to comment on a hypothetical mobile product before the end of the month. Like what he’s learnt since mojo 1 about optimization of WTA algorithm, importance of WTA2 algorithms, addressing...

    Hugo M Scaler by Chord Electronics - The Official Thread

    I actually just use the stock Toslink cables that came with my M-Scaler and DAVE because I find third-party cables can often be so big that it's easy to incompletely insert the cable into the M-Scaler/DAVE socket, resulting in a smeared sound. Moreover, if you're going to compare, just make sure...

    Same bit-perfect source (no volume adjustments), same DAVE, same headphones, same song, -5dB to +20dB difference in listening volume compared to me.

    CHORD ELECTRONICS DAVE

    If you're going to EQ and your EQ just lowers the volume at certain frequencies, you shouldn't need to use Headroom management. However, if your EQ settings would increase the volume at certain frequencies, you should enable Headroom management. For example, if the maximum EQ is say +5dB at 1kHz...

    CHORD ELECTRONICS DAVE

    The moment you DSP the signal you’re sending to M-Scaler, you’re degrading the sound. First, the EQ/convolution filter probably is not sufficiently accurate despite supposed 64-bit accuracy. But the bigger issue is that Roon would presumably then have to dither that EQ’d signal back to 24/32-bit...

    Hugo M Scaler by Chord Electronics - The Official Thread

    I think to start, you can try going from your PC to M-Scaler using a Toslink cable instead of a USB cable to see if you like the sound better. There is a Toslink cable that comes with your M-Scaler (and I think Hugo TT2 too). Although not all PCs have Toslink output and even when they do, the...

    29th is my last day on call for the year so if I’m lucky, I can make it for the 29th evening. Perhaps that’s the best day for all of us so far.

    CHORD ELECTRONICS DAVE

    Having listened to the Topping at my local Head-Fi meet, I can say as with all DAC chip DACs compared to DAVE, I hear these same issues with non-Chord DAC chip DACs: 1) Noise floor modulation that makes the music sound bright and harsh. To me, that’s the sound that “Digital” is famous for and...

    CHORD ELECTRONICS DAVE

    The issue with the NAD M22 is that it is a switching amplifier. So even though it might have a lower noise floor and more power than the C275, the amplifier probably switches at around 500kHz whereas DAVE first upsamples to 705/768kHz and then further upsamples to 104MHz with noise shaping to...

    Watts Up...?

    So under Advanced sound settings, I just choose Audio Video Sync to be 660ms, Dolby audio processing on, select formats: Auto. And then on my Panasonic TV, I do have to use it to downmix to stereo. I am aware some TVs can’t do that. But mine works and sounds fine.

    This would be referring to Chord QBD76. I had it for years before my DAVE upgrade. I realized it was something special when I first heard it. Been a Rob Watts fan ever since.
