    CHORD ELECTRONICS DAVE

    Also, while you're experimenting, make sure you don't have a server or laptop sat just a few inches above DAVE :) I made the mistake of placing HMS about 5 inches below DAVE until I thought "I wonder...". I believed the cases would provide enough shielding, but I was wrong. Luckily HMS with...

    CHORD ELECTRONICS DAVE

    A lot of Naim pre-amps can't cope with how loud DAVE is in DAC mode. DAVE's pre-amp mode sounds identical in terms of quality. Find the sweet spot for the volume so that the Naim gear doesn't get upset. You've probably discovered that radio frequency noise is an issue with DAVE. So I recommend...

    Maybe Rob's power amplifiers? Those of us who primarily listen with passive speakers will be happy.

    See my signature. Yes. See my signature. In my original experiments with clip on ferrites used on a USB cable I found that with about 10 ferrites there were sound quality problems, even though there were also benefits: bass and midrange were improved and mostly the treble, but there was an...

    CHORD ELECTRONICS DAVE

    I was at Nintronics all day yesterday listening to speakers, fed from Aurender -> USB -> M Scaler -> dual-BNC (stock? looked like stock) -> DAVE. We had exactly the same problem. Occasional clicks in just the right channel (usually gaps of 20 or 30 seconds between clicks). This was the final...

    Watts Up...?

    It is a LIE that clip-on ferrites make the Hugo M-Scaler connection over dual BNC to DAVE worse. If you hear a problem it's because you're using an intermediate number of ferrites. Of course if you sell cables that costs thousands of pounds based on the lie that clip-on ferrites make the sound...

    So this evening I was briefly sat not listening to music and I could hear hiss from my speakers! That's not right I thought, DAVE driving my speakers (91dB/W/m at 1.6m listening distance) is absolutely silent. Why is there hiss? OK, so I've got the volume a bit louder than normal, but DAVE never...

    If you are using the WAVE cables between HMS and DAVE, then perhaps the WAVE cables are not doing their job. But, to be sure, I would recommend putting lots of ferrites on your DAVE mains cable - see my signature. DAVE is sensitive to noise through its mains input, but it's not a massive...

    Try optical into Hugo direct, if you can, from your laptop.

    I didn't do that comparison as I'm only interested in making sure that the ferrites on the BNCs with HMS in pass through produce absolutely no change in sound quality compared with DAVE alone :) And USB and optical sound identical, proving that the ferrites on the BNC are doing what they're...

    The only comparison I've done is optical direct to DAVE with HMS unplugged from the mains and BNC cables unplugged from DAVE versus optical or USB (1m with no ferrites added, except it has two built in) into HMS with passthrough mode. I couldn't find any difference, so that was the end of my...

    My theory is that when you use a few ferrites, 10, say, the effect is strong enough at a narrow range of frequencies to result in a difference being heard. But at other frequencies the effect is too weak. I think this produces an "unmasking" effect, where a problem is revealed due to another...

    It seems unlikely that the FPGA is switched off while in pass-through mode, so continued RF generation is likely. Someone with a device that measures power draw should be able to determine if there's a change in power consumption from 1 million taps to pass-through. "Pass-through" mode is not...

    Watts Up...?

    Seems like it would be at the cost of a visit to a CanJam and persuading some people there who have the components to help with a comparison in a quiet room, e.g. after hours in a hotel room.

    The problem I have is when I start music playing, or when I manually change to another track, there is one or more pops. The first one always seems to be at about the same time into the track, which makes me think it has something to do with the way DAVE locks on to the clock. But that's just a...
