    HEDD Announces HEDDphone With AMT Technology

    My Metaxas Solitaire is the best speaker amp I've ever heard, by a great margin. Its main feature is the extreme bandwidth, which it shares with the likes of Spectral and the new Chord Étude. During an inspection I had the Swiss importer/distributor make a modification consisting of removing the...

    HEDD Announces HEDDphone With AMT Technology

    The DAVE provides 6.8 volts with a digital zero signal at +5 dB (1% HD). My –13.5 dB scenario is 18.5 dB lower than that – so there goes your peak-power hypothesis. :stuck_out_tongue:

    HEDD Announces HEDDphone With AMT Technology

    There are numerous examples (posted on this forum) showing that a weaker amp can sound better than a stronger amp as well. So don't draw hasty conclusions as to more power is better. Enough is enough. But certainly different amps will sound different, also in terms of quality and accuracy. It's...

    CHORD ELECTRONICS DAVE

    Except that what you lose with engaged crossfeed with your headphones you also lose with speakers without crossfeed (low-frequency channel separation), so this conjecture is illegitimate. What some might prefer, though, is the artificial widening of the soundstage at low frequencies through...

    It's certainly not ideal, but better than if it hadn't happened at all.

    Crossfeed settings are only accessible with a headphone plugged in, but still active through the line outs. So take care to disable crossfeed beforehand when you're going to listen through speakers! One more thing to note: The higher the crossfeed level, the higher the bass emphasis. That's A...

    Hi Jarnopp Yes, I have it since more than a week now, but actually wanted to wait with posting impressions, with just about 45 hours on it. However, since you're asking... It wasn't love at first sight at all. Wearing comfort was the least issue: The weight didn't bother me, just the...

    Hugo M Scaler by Chord Electronics - The Official Thread

    Rob's statements say nothing else but that you can renounce ferrited dual-BNC cables between M Scaler and DAC if you feed the M Scaler with battery power, hence break the loop via ground connection. This explicitly addresses the RFI from the M Scaler reaching the DAC via dual-BNC cables. As...

    The (new) HD800 Impressions Thread

    Note that my rating and appreciation for this combination is based on listening experience, not just numbers. And when it comes to fast reaction to the input signal, the Hugo₂ alone is definitely faster than with any additional amplification stage in the signal path – also and particularly to my...

    Hugo M Scaler by Chord Electronics - The Official Thread

    It's not quite obvious, and I never would have known about it if Rob hadn't mentioned it: The RFI produced by the M Scaler does its bad work only if it finds a loop to the DAC via earth on the power-supply side. If the latter is blocked by a battery, it won't be an issue. That's the state of...

    The (new) HD800 Impressions Thread

    Given the HD 800's high sensitivity, the Hugo₂'s power reserves are luxurious. Enough is enough. But you can't have enough purity and transparency, which you inevitably compromize with re-amplifying the signal – something you kindly omit in your argumentation. I own both the HD 800 and the...

    The (new) HD800 Impressions Thread

    The Hugo₂ can drive the HD 800 perfectly. Any additional amplification stage will degrade the signal. It would be like re-amplifying the signal from the headphone output, since line out and headphone out share the same signal path – no internal headphone amp to be bypassed.

    ¼" and balanced 3 m each, ⅛" 1.5 m. A better (sounding) cable is recommended, though (Lavricables, Norne Audio...).

    Hugo M Scaler by Chord Electronics - The Official Thread

    As a big fan of the DAVE/HE1000se pairing I'd say that's my mumber one recommendation. I have the HEDDphone on order, though, but the brief audition that has led me to go for it is not enough to compare it with the HE1000se. It's a bit more power hungry, but shouldn't pose a problem for the DAVE...

    HEDD Announces HEDDphone With AMT Technology

    In my case the M11 Pro only serves as digital source feeding a Chord DAVE via Hugo M Scaler. The DAVE's headphone output is quite powerful, so I'm optimistic that it will be a good match with the HEDDphone. It definitely is with HE1000se and HD 800, it could also drive a Susvara to my...

    HEDD Announces HEDDphone With AMT Technology

    Yes, I'm aware that high frequencies generally and especially those above ~10 kHz can't be reliably measured and the deviations with pinna shapes (HRTF) are another factor to be considered. That's why I just use the disposable FR graphs as a starting point, from which the obligatory adaptions...

    It looks like he was using sliders for adjusting the values instead of numbers. However, the difference between a Q of 4.38 and one of 4.5 may be audible under some circumstances.

    HEDD Announces HEDDphone With AMT Technology

    I will have a look at Oratory's curve as well (if I can find it), and then there's also Jude's measurements... Actually you're right – the dip is at 6 kHz, not 4 kHz (my fault). Jude's midrange looks quite different to Crinacle's. Nothing new: A single FR measurement can't be trusted, it's...

    Hugo TT 2 by Chord Electronics - The Official Thread

    I guess that's a misunderstanding. He explicitly stated that he wasn't using it with the rear (XLR) sockets – and that the adapter has worked fine with his Violectric V281 amp.

    +7 dB doesn't necessarily mean clipping. Clipping just occurs with signal peaks reaching -0 dB, = full level in the digital domain. That means a recording that never reaches higher than -3 db won't begin to clip before +10 dB.

    Hugo M Scaler by Chord Electronics - The Official Thread

    Meanwhile I have received a USB C → USB B cable, and my first reaction was: «Hey, USB sounds even smoother and finer resolving than S/PDIF!» But the comparison is flawed, as it relates to the last listening session of yesterday evening. However, I will definitely stick to USB, and be it just for...

    So apparently you can't answer my question, instead choose to be sarcastic. For controlling membrane movement you have to use motional feedback (à la Philips MFB or Backes & Müller's implementation). An amp alone can't control the movement of the membrane, it can only move it. The only sort of...
