| Purifi Class D: Junk? I will note one thing though- I've seen a number of SMPSs (Switch Mode Power Supplies) used in class D amps. I think its a bad practice. They work, sort of; the problem is that class D amps go from almost no current draw at idle to quite a lot ... | |
| Purifi Class D: Junk? If you like or need volume, that "pathetic" 20W amp sound quite anemic. So it doubles to 1 ohm. If I have inefficient mainly 8 ohm speakers it will still be anemic. There is no magic in a 160W into 1 ohm amp that halves in power all the way to 8 o... | |
| What makes speaker's sound big? Meh, that is low fi budget constrained. Everyone knows the best cables are good for at least 72 hours. | |
| Purifi Class D: Junk? 02-21-2021 7:17pmWhat you are hearing is what class d amps do they produce high wattage with low current to save money on energy and expense of manufacture to make more money for the manufacturer and they will not have the required current to ... | |
| The guru on fuses: So, you of course have measurements confirming your hypothesis, not to mention calculations putting some bounds on the effects? You are pretty much stating the obvious, like cables have resistance, but without quantifying it does not mean much. | |
| What makes speaker's sound big? ^^^ --- Well this is pretty much made up nonsense --- ^^^Not much else to say. This is just ignorance of how to properly integrate subs. | |
| The guru on fuses: OMG ... do you even know how "sound" travels in a material. Transverse waves are not the only method. Even solids have longitudinal waves. When vinyl is cut, it is intentionally cut at reduced speeds to reduce impacts of vibration ... you know th... | |
| Purifi Class D: Junk? This is what it says, "Furthermore,the NC500 OEM is an unbuffered amplifier leaving the implementation of an input buffer up to the manufacturer. The NC500 is practically devoid of any sonic signature so this external buffer is a good way of tunin... | |
| Internal Wire Gauge? Yes bad use of wording by me, jacketed is more appropriate, as opposed to shielded, however, there are a ton of wires that would be suitable, meet UL (or other standards), and have a 600V rating. However, unless you passing near another wire and/o... | |
| The guru on fuses: It was a fine but failed attempt to appear superior theaudiotweak, but digitally, if someone cared, you can actually differentiate from the initial signal and reflections quite effectively in the digital domain similar to how Kippel can achieve an... | |
| What makes speaker's sound big? Audiogon, where the science of audio goes to die ....For a point source with an unencumbered spherical radiation, SPL reduces by 1/R, or it is 1/2 at double the distance (-20log(0.5) = -6db. Sound intensity (power) reduces by R squared. Human's ar... | |
| The guru on fuses: I have read your posts Miller, unlike you, people, like actual professional people in the music industry, come to me when they want to learn. Real things, like actual things that happen, not made up stuff. You keep up with that delusion. maybe bet... | |
| The guru on fuses: Glad I have you thinking and exploring things you never had..See what Caykol wrote. That is what I am thinking. | |
| What makes speaker's sound big? Clean SPL (in your room), Clean Bass Extension, Your eyes.Everything else is just meaningless fluff.You can either achieve a desired SPL, at your listening location, over a desired frequency range, in an undistorted fashion or you cannot. That S... | |
| Internal Wire Gauge? And yet $100,000 CD players (and amps) are built on PCBs using generic copper, typically FR-4 substrates, though I have seen the odd PTFE, though their is little justification for it.PTFE (Teflon like) insulated wire does not need to cost an arm a... |
