The "black box" statement is false. In fact, high frequency noise can cross into a device's power supplies and ground plane. Some products are more susceptible to it than others -- generally a device with a beefy power supply with lots of capacitance will reduce the noise input a great deal...

They take your AC mains power, run it through a transformer and generate a pure AC output on the other end. The concept is that by doing this, all the high frequency noise that comes in from the public utility lines is kept out of your audio system. They are popular solutions with high end...

Well I've spent over $500 on carpeting and acoustic panels. My entire living room was made into a listening room. I got a pair of those new Chane 1.4s (bookshelves) and a Teac integrated (which claims to use an ICEPower amp so it shouldn't be garbage) to power them. Veiled, rolled off, BORING...

Most people say that after a certain point, high end headphones stop making sense and money is better spent on speakers. But the hard truth to face is -- speakers aren't nearly as resolving as high end headphones, and getting than the center image from loudspeakers takes an optimal room...

I'm sure people who are into pro audio have browsed the Sweetwater catalogue and lusted after Antelope Audio gear. They may be endorsements but are they outright lying? I'd assume professional audio producers are more clinical and balanced in their listening impressions than hobbyists. Would a...

  The mathematical formula are useful for engineering, but worthless in a context of understanding natural phenomena which is what we are discussing. The natural phenomena in question are electrical currents. Are square waves, in fact, electrical currents? Do they differ fundamentally from sine...

I don't think you were addled by sighted and expectation biases. More likely you suffered from audio memory smearing.    Besides, I don't think anyone would have a severe expectation bias over $6 headphones.

With my lo-fi headphones (HD668B, K553) and mid-fi headphones (HD600) not only is EQ recommended I find it necessary to correct the worst FR imbalances. With any of my hi-fi headphones (HE-6, TH900, Utopia) EQ is worthless and all attempts result in making the headphones sound much worse than...

The claim that MQA unpacks high-resolution audio in an MQA DAC is true. Wether using Tidal or streaming an MQA file via other software, the blue "MQA studio" lights up. It even works if you transcode the 24-bit FLAC to ALAC. Others with Mytek DACs have reported MQA files showing up as 88 or 96...

The Mjolnir 2 is my favorite Schiit amp. I've auditioned most of them except for the little baby ones and the Lyr 2. The Ragnarok had this very annoying upper-mid grain / hash issue with the volume turned up, possibly caused by its reported current starvation / bias control issue. The Joutenhiem...

I bought an Meridian Explorer 2 to evaluate the impressive specs of MQA -- high definition audio packed into a 44.1 24-bit stream, DAC correction and analog-to-digital studio correction. The high definition claims are definitely true.

  I responded to the question with "of course".   I went on the explain some key benefits that a hardware balanced DAC will bring.   The fact he felt the need to ask that question to begin with suggests he's laboring under some kind of misunderstanding about what "balanced audio" is. I...

Jitter is consciously perceptible at fairly high levels. Any modern DAC, even little baby Chinese DACs, have a clock that are good enough to reduce jitter to levels that are not perceptible as jitter. So the battle isn't with old-school, extremely obvious jitter.   Instead of just explaining...

You guys are seriously contorting yourselves out of shape. A square wave does not have infinitely fast rise and fall times. The difference between a 1 and a 0 is infinite, and can only exist in our imagination. We pretend that a voltage change across a given threshold inbetween slices of time...

I commented on the analog transmission of digital signals. Trying too hard to find fault in something I said several posters jumped on it. Although I'm starting to wonder now if they are legitimately confused about the difference between digital and analog. Digital is 1s and 0s. But 1s and 0s...
