| DC Offset Blocker/Killer - where to buy in the USA You got a bit of bad advice. Mechanical transformer hum comes from having DC on the AC line. Isolated lines or ground do not help you. First check your AC for DC. An electrician should do this.This can be caused by lights and dimmers elsewhere in ... | |
| The Future of Audio Amplification Maybe the question we really should be asking Kosst and George is this:What, exactly, are the audible effects of switching distortion in a Class D amplifier, and can you give specific examples, with speakers, that you have heard this from? Like al... | |
| The Future of Audio Amplification Also, this nonsense about caps burning up early due to the switching technology is a lame attempt to scare people in an era where fear reigns supreme. Good electrolytics last a long time. Enough of this fear mongering. In the amps or speakers... | |
| The Future of Audio Amplification I don’t recall the amp model, but Pass installed a pot on the front of the thing to dial in the distortion character ranging from a few hundredths % positive phase second harmonic to a few hundredths negative phase. Pass makes the opposite argume... | |
| Magicos are chesty Not really, these are all gated measurements.Wow, sounds pretty high tech. | |
| Computer power cord upgrade, is it worth it? The issue with PC's is to keep the noise the power supplies generate out of your AC. A shielded cable will reduce EMI/RFI from being emitted. These are cheap. Keeping the AC cord plugged in outside of your audio gear's noise/surge protection is al... | |
| The Future of Audio Amplification No one has provided a logical, technical counterpoint to kosst's argument regarding class D other than experiential vignettes. No one has proven the measurements Kosst has alluded to are audible on the other side of a speaker. All Kosst has done ... | |
| Hum in a phono cartridge? When you unbalance the phono cartridge, you connect ground to neutral. If you mean AC, then no. Otherwise, are you calling ground the preamp shield conductor and neutral the catridge (-) ?? | |
| The Future of Audio Amplification @georgehifi There’s a reason for it, it’s there and real, and if you can’t hear it, fine. But please, don’t tell others they can’t, when they can, and the measurements back them up. George, All you do is tell others they can't be happy with Clas... | |
| Magico A3 vs S3 MKI Vino, Where there seems to be the most disagreement about the Magico’s has to do with the lower voice and piano registers as well as the treble tilt. I encourage you to listen for yourself, and make sure these areas are what you like. Some have su... | |
| Hum in a phono cartridge? @cleeds OK ... help me out a little here. But even if it gets grounded at the phono input, that is a single ground reference. Where's' the competing ground that the phono catridge attaches to? I'm not trying to be difficult here... I'm just genuin... | |
| The Future of Audio Amplification The evidence of my ears are telling me Class D must do distortion right. Go figure! Exactly. I’ve also heard megabuck class-A amplifiers around the time I got my Class D. Honestly preferred the Class D. I’ve had several audiophiles in my home and... | |
| The Future of Audio Amplification Go to Stereophile and look at the last 5 or 6 class D amps they’ve measured. Unless JA applies a low pass filter on the AP the output signals look horrendous. Even with the low pass filter, they all have ringing. I was just looking at the Below C... | |
| Random blast of 0db white noise. Why would a DAC output an analog signal when losing lock? Because the DAC gets confused about where to start reading music within the data stream. Think of the data not as music, but packets, or envelopes. Each packet has more data than just music... | |
| Hum in a phono cartridge? So, my statement was "Balanced and isolated"Where is the ground contact happening at the cartridge side? I'm honestly curious, as I've not touched a turntable in decades. |
