    Watts Up...?

    About a year ago I looked into that very issue with new filters. There have been some small benefits, but as you get higher in frequency the benefits of WTA diminish rapidly. It seems that the ear/brain is sensitive to the area of the transient error; as you double the sample rate the area of...

    Hugo TT 2 by Chord Electronics - The Official Thread

    No I haven't but I am very eager to give them a try. It's tough that the USA won't let us Brits in, as I could have heard them at Socal, and that CanJam London is now postponed to next year. Hopefully NY CanJam in February? Can I wait that long?

    CHORD ELECTRONICS DAVE

    Thanks for your kind comments, and no you didn't put me on the spot - I am always happy to clarify, and never worried at all about being challenged on technical aspects.

    CHORD ELECTRONICS DAVE

    Opto-DX will only isolate completely if both sides of the Opto-DX are battery powered - otherwise you would get RF leakage via the mains. But if you are going to the trouble of installing batteries you may as well do it on the M scaler - then you would get 100% isolation too. I can see why you...

    Hugo TT 2 by Chord Electronics - The Official Thread

    4 ohms with TT2 SE is absolutely fine as the OP stages were designed to suit low impedance loads (like my B&W 803 D3) which are 3 ohms from 100Hz to 800Hz. Whether the volume level is enough depends upon you and how far away you are from the speakers, as you will only get unclipped a max of 95...

    Watts Up...?

    I have no knowledge on the Primephonic app. But it sounds like the app is not converting compressed music bit perfectly - it is upsampling too. You need to ensure that the app gives you the original sample rate of the file - that's the reason I show the incoming sample rate. The sample rate...

    Watts Up...?

    The display flickering is due to lack of lock. Sounds like Dave needs to go back to Chord for a check-up.

    Your best bet is to contact Chord support - either through your distributor or direct to Chord.

    Watts Up...?

    So the power dissipation is pretty constant 12-13W whether it's muted or just playing as a DAC or regular headphones. Driving 8 Ohm loudspeakers the power will increase from this. Yes standby on TT2 is fine - the primary power circuits are all working, but the OP stages are off. If I wasn't...

    It does - see page 34 on manual on Chord's website. I don't write the manuals, and its not an easy job either! Happy listening.

    CHORD ELECTRONICS DAVE

    A lot of work has been done on this very issue, and more work is ongoing. Suffice to say that I should have some news next year. I suspect that you are correct - to perceive depth properly we need the depth cues to be preserved in amplitude and relative timing (phase) as accurately as...

    Watts Up...?

    Electronics are more reliable if left on. If you are worried about the 12W or so power consumption, then use the standby - this keeps the clocks running. I keep my TT2 and Dave on all the time.

    Watts Up...?

    I can't really comment on Chord's launch plans, but Covid is making things very tough for any manufacturer with long and complex supply chains - let alone the uncertainty of being able to do events and shows for new products. Fortunately, Chord have a policy of maintaining large stocks for...

    Hugo M Scaler by Chord Electronics - The Official Thread

    The problem is that you are not appreciating the scale of the problem. So a little while ago, I was listening to the sample rate conversion for the ADC project. This used my 67 bit Lagrange interpolator running at 104 MHz, and I initially started simply with first order, and pS interpolation...

    Watts Up...?

    TT2 is quite a bit warmer (in a good way) in tonal balance than Hugo 2; so when I travel, I take a TT2 with me for hotel use, as the SQ difference is worth the hassle. But it's no where near not a big enough difference to use a TT2 on aircraft (unlike the M scaler for example). So Hugo 2 is...
