    Any point of external DAC+AMP with new MacBook Pros?

    I have a M1 MacBook Pro 16 with these new updated headphone outs. I use a Khadas Tone Board + JDS Atom Amp 1 with a Sennheiser HD650. I can push volumes to uncomfortable levels using the built-in 3.5mm port on my MacBook, even when using DSP + -4 dB ReplayGain + headphone EQ. My question is...

    20 meter between PC <> DAC

    Hi, how would you recommend connecting a PC with a DAC which is 20 meters away? AFAIK, I have two options: - active USB 2.0 cables - Toslink cables With both solutions I'm worried about if there is degradation in jitter and also bit-loss. Also, for the Toslink cable, I'd need to basically buy...

    USB-C cables: active / passive / E-Mark chips effect on audio quality?

    I have a Macbook Pro M1 and I'd like to connect my USB-C desktop DAC to it. My question is that there are a zillion types of USB-C cables and I'm totally confused about them. Basically, all I'd need is a very simple USB 2.0 data cable with Type-C plugs on both ends. What I can see in the shops...

    Acoustic music energy distribution

    I'd be interested, that for acoustic music or human voice (that is non-electronic music), how is the energy distribution over frequencies. I'm asking this because I'd like to know if a Topping PA5 or a Hypex NC122MP would be objectively better for acoustic music. Basically, here is a mix of the...

    Are amplifier clicks and pops damaging speakers?

    I have an ICEPower 125ASX2 based poweramp, which when I turn it on makes a very slight pop noise. It really is not loud, much more quiet compared to how I'd listen to music even at night. My question is that do I need to worry about this damaging my speaker, if I turn the amplifier on/off once...

    Basic question about connecting mains (IcePower DIY build)

    I have a VocoPro Feather Amp FA-500 board, which I bought for its 100% genuine IcePower 125ASX2 board + case + connectors, and because it's been on a good sale at $100 (+ shipping + import duty ended up $175). The official IcePower board itself would be 200+ GBP in Europe. Out of the box, it...

    AB testing tool for macOS

    Hi, For the HD Audio Challange II (which I absolutely recommend to everyone in the forum interested in our hearing), I'm looking for a macOS based software which allows me to do this. It needs to be bit-perfect and support 24/96 audio playback. I've tried the "Lacinato" tool, but it makes a...

    iPhone + USB DACs any good? Bit-perfect? HD?

    Hi, Is there anyone who did any test on the bit-perfectness of an iPhone when used with USB DACs? I was thinking about making a Raspberry Pi streamer, but I was thinking that if I can use my iPhone that'd be much better. Not one more computer with an operating system, which needs to be updated...

    Recommended internal cables for amplifier kits

    I'm trying to build / mod some Class D kits (ICEPower, Tripath modules). So about internal cabling, what are exactly the recommended cables for power, signal and speakers? I have some questions. - power: I don't understand why is it better twisted than straight. In the walls, in the power...
