| Diminishing returns? What is this "last 5-10%" concept? Is that also not linear? Is it iterative, or recursive, or fractal, or exponential? Or something else? It can't be turned into numbers, its a qualitative change. For the closest analogy, find one of those a... | |
| Confusion about TDA7388 @hollowman : Just as on DIYA and AS, you're trolling. | |
| Confusion about TDA7388 You can't parallel the outputs for more power no. More power requires more volts. But you can parallel to drive a lower impedance driver and get more power into that. You'd need capacitors to parallel the outputs due to the DC offset.ST-BY means '... | |
| Review: Holo May (L2) DAC and the Musetec Audio (LKS Audio) MH-DA005 DAC Compaired Excellent write-up. Especially appreciated is the choice of music (differing from the majority of DAC reviews) as I'm a classical lover. | |
| Can LM224 be used to process an AC signal? To have an LM324 (the more well-known variant of this chip) handle an AC signal its necessary to have either two power rails (positive and negative) or a mid-rail generator circuit.Better to ask this question on DIYAudio I reckon. | |
| Are all amps being built wrong? ... why are amplifiers not built as a high impedance current source? Mainly because speakers are designed to be driven by a low impedance voltage source. When amps and speakers are co-designed though there exists the possibility to use current ... | |
| how is digital sound created? It’s all part of error correction, all part of the Reed-Solomon code, and I actually quoted the exact math that applies. If you're claiming that interpolation is all part of R-S coding that wouldn't be correct. Interpolation is specific to audi... | |
| how is digital sound created? You are mistaken. Interpolation is "guessing" by definition (in this context) and interpolation is part of the CD standard. @yage was talking about 'error correction' and indeed that is done without guessing. There is a stage beyond error corre... | |
| Help! Is there standardization in i2s? I2S is an electrical specification, not a mechanical/physical one. Vendors using it outside their box normally turn it (I2S is single-ended) into an LVDS set of differential signals. The allocation of those signals to physical pins in the HDMI con... | |
| How can i improve the sound of Iphone 11? I found a step-down trafo (2:1) improved the SQ of my Meizu phone. A bit bulky to carry around though. | |
| Class A Power in A/B amplifiers? George - yep, and the old torch bearer is yapping at my heels! Eeeek! | |
| Class A Power in A/B amplifiers? The class A power for a classAB amp is a function of the standing bias current in the output stage. But also relevant is the load impedance - running with 4ohm speakers will halve your classA power compared to 8ohm. | |
| Philips TDA1387 and TDA1545A digital-to-analog converter (DAC) not getting the point of all this Trolling is the point. | |
| TDA7492P vs. TPA3116D2 I've not heard TDA7492 but TPA3116 was rather weak in the bass with an unruly top-end - could not recommend. Both are rather old designs nowadays - more modern ones to look into are TPA3221 and MA12070 and both of these sound a LOT better than TPA... | |
| what is the purpose of the analog part in the DAC The "I/V stage" is an analog stage and it is required at a minimum. The job of the I/V stage is to take those DC pulses as an input and help to try to form that into an analog waveform. This isn't accurate. Not all DAC chips need an I/V stage,... |
