| new GAN amplifier No that is not an opinion that is a experience. The drive requirements for a set of bipolar transistors and a set of mosfets is much much different. Add in different biasing requirements, different thermal compensation, different bandwidths for a ... | |
| The Truth About Power Cords and there "Real" Price to Performance dimora,Did you know the instaneous voltage drop on a 50 foot run of 12awg can reach 3-4 volts when you get the 30+ amp peaks of some power amplifiers? You had not mentioned whether you were discussing cords or house wiring at that point as well, ... | |
| The Truth About Power Cords and there "Real" Price to Performance Of course, that had nothing to do with the GT audioworks speakers working reasonably well in typically awful trade-show rooms, nor the designer undertstanding how to get the most out of his speakers in that situation .. nor all the other good qual... | |
| new GAN amplifier This, what you wrote below, I cannot just accept on the face as factual. The drive requirements, biasing, temperature compensation, bandwidth vs. drive, etc. are so significantly different between a BJT pair and MOSFET pair, that unless you essent... | |
| How Science Got Sound Wrong terry9,Here is a paper, it is about ultrasonic imaging, but that is simply a scaling issue w.r.t. frequency. It has nice graphs that clearly illustrate the ability to extract timing information and shows them as a function of sample rate. Even at ... | |
| How Science Got Sound Wrong Once again, GeoffKait enters the argument, makes personal insults and jokes, adds absolutely Nothing to the argument, and hijacks the thread making it useless. Unlike Geoffkait’s posts, which are nothing but personal attacks, deflection, and obtus... | |
| The Truth About Power Cords and there "Real" Price to Performance mambacfa,Not to rain on your parade, but if your test had been made blind, i.e. you had no clue what cord was attached at any point in time, your test would have validity. You may think you have superhuman hearing, but you could have just as easi... | |
| The Truth About Power Cords and there "Real" Price to Performance Not sure what your correct gauge for the circuit is supposed to convey. I am not arguing one way or the other, I just don't see the relevance. Peak currents on the AC waveform can be higher than average rating to AC waveform modulation at the equi... | |
| new GAN amplifier How can you know "what to listen for" wrt transistor type when you don't even know the underlying amplifier topology and distortion mechanisms, intentional voicing, damping versus frequency, bandwidth, etc. You simply can't. You can't take some... | |
| How Science Got Sound Wrong terry9, here is an example that someone created that shows an example of what I am discussing w.r.t. subsample timing:.https://www.dsprelated.com/showcode/207.php https://www.dsprelated.com/showarticle/26.phpThis is fairly simple paper that looks... | |
| How Science Got Sound Wrong The problem is GK, is that he is Not a world expert, not even remotely on the underlying topic of this whole article. He is an expert on physics and and neurobiology. He is absolutely not an expert on digitization, digital signal processing and re... | |
| new GAN amplifier I am going to go out on a limb and say you wouldn't know without being told if the amplifier had FETs, BJTs, etc. Topology is going to make far more difference to the sound. | |
| How Science Got Sound Wrong Your brain measures the phase difference of the same signal reaching both ears. Errors in phase of a sound primarily from one speaker will not affect the measurements. Errors in phase from a sound from both speakers only matters if the phase shift... | |
| The Truth About Power Cords and there "Real" Price to Performance You can never record and make any analysis with microphones or YouTube. Has to be live. I am in Atlanta regularly. Count me in! | |
| The Truth About Power Cords and there "Real" Price to Performance Have to disagree. Your greatest determinants are your speakers and room, followed by your TT setup if you are doing vinyl, and then your amp. limbc2 posts11-15-2019 7:00pmIf you hv ultra deep pockets, its nice luxury to spent BIG sums on hifi to ... |
