    Testing audiophile claims and myths

    I'm jumping in late here... but it seems to me that the ENTIRE point has been missed. If you want to make an analogy between images and sound then the color range of a JPG image is NOT a good choice. The main issue with lossy compression is NOT the EQ or frequency range of the music - although...

    Testing audiophile claims and myths

    First let me admit that I sort of skimmed the video.... I did watch all of it... but not all carefully. First - I agree with you entirely - there is no reason for "a more expensive cable" to be able to do ANYTHING better than a cheap cable in terms of actually transmitting the signal to the...

    Testing audiophile claims and myths

    I would agree - provisionally. Some audio circuit designs are very sensitive to even minor variations in supply voltage. However, some circuit designs are virtually immune to them, and can tolerate huge variations in supply voltage with to measurable change in performance. The specification...

    Testing audiophile claims and myths

    That makes perfect sense to me. With analog sources it's quite possible for a noise like a tick or pop to very briefly exceed the maximum level of the normal signal - by a very significant margin. A tick or pop coming from a vinyl album may also contain very high levels of very high or even...

    Testing audiophile claims and myths

    Let me try to clear up a few things. A balanced signal does not include a "hot" and "cold" signal - even though they are sometimes described that way. The (+) signal is a full level in-phase signal and the (-) signal is a full level signal that is inverted (exactly 180 degrees out of phase with...

    Testing audiophile claims and myths

    I agree entirely... to a point. You have no absolute reference.... but at least you have a relative reference.... and that works for you in two ways. 1) If you have some favorite music that you always use when auditioning equipment then, even though you may not know what that music sounded...

    Testing audiophile claims and myths

    There are a whole bunch of little "DSP boxes" with a variety of purposes. The popular "Mini DSP" boxes, which are really just general purpose audio DSP boxes you can load a variety of software on, can be loaded with a variety of filters and software - including crossover filters, room correction...

    Testing audiophile claims and myths

    That's been my experience. I would note that the different streaming services vary wildly in terms of what they have available. The new Amazon Music service seems very good - and has lossless files. Spotify probably still has the best coverage - but their sound quality is sometimes lacking...

    Testing audiophile claims and myths

    I don't get your comment. At least so far, I can stream all the music I want, AND own actual copies of the stuff I really care about. If you're referring to the fact that we always seem to get screwed by somebody, at least if they can figure out a way to make a few extra bucks... that isn't...

    Testing audiophile claims and myths

    I'd have to say that I fall firmly on BOTH sides of this one. I personally NEVER read the liner notes on CDs. If I'm curious about the details I generally just Google them. Therefore, when I acquire a new CD, it immedlately gets ripped, and the plastic gets tossed into the closet in a box...

    Testing audiophile claims and myths

    To a degree you are correct.... however there are major differences between video and audio.... and, in the end, I expect them to make a significant difference there. What you have described about "what we all expected cable to become" is actually largely what it has become. My cable service...

    That's what I would expect based on their description. According to what they say, their process burns the same data onto the disc, but does so using a slightly more "conservative" physical format. As with most specs, the Red Book CD standard sets a minimum and maxiumum range for pit and gap...

    That sounds like a good - and readily available - solution.

    Testing audiophile claims and myths

    Amazingly - some people just like to know how the stuff they use actually works. However, in this case, a lot of people seem to have less favorable experiences with CDs than you have. (Which tends to make many people even more interested in how they work - and the details about why sometimes...
