| high frequency intermittent noise I am afraid the US are sometimes a third world country, and this is one of those areas. Hope you can figure this one out. Can you find someone with a mobile phone to stand next to the subway line, or can you hear the trains when the windows are op... | |
| high frequency intermittent noise Those ancient subway trains can probably produce quite a bit of power line pollution, but I would expect that system to be completely separate from the domestic power, given that trains run on much higher voltages. Still, your domestic power syste... | |
| high frequency intermittent noise I could not quite figure out what happened when yo used a battery powered radio. Does it come through your power lines or through the air? | |
| For tube sound, which is more important: preamp or power amp? Price may be high but manufacturing cost not necessarily. | |

| Room acoustics REW is indeed very good. And to see what is going on the waterfall graphs are most instructive. They show that peaks are not just peaks but are also an issue in the time domain, by lingering on and giving you that feeling of ’slow’ bass.For those ... | |
| Top Audiophile Ethernet Cables - any comparisons? Am I right that the executive summary of the event is that, apart from the enjoyment, neither of you was able to reliably tell a difference? | |
| Question from newbee: misic streamer for beginners Chromecast Audio, for $35? It willl play Tidal, Spotify, TuneIn internet radio, etc. The inbuilt DAC is pretty decent and good enough to start experimenting. If you want something better, you can later add a modern high quality DAC. | |
| AURALiC Aries price reduction From what I can see your GT40 only has a usb input so it will not work with the optical digital output of the Chromecast. You would need to use the analogue output of the Chromecast. Its built in DAC is not bad at all, so I guess the sound quality... | |
| Would you buy a 12-14 year old Integrated? Amplifier design has matured a long time ago, so new is not necessarily better. I have three power amplifiers. A Quad 303 from 1970, a Quad 405-2 from about 1992 and a Quad 606-2 from a bit later again. All sound absolutely fine, even if the bigge... | |
| Room acoustics This may be the moment to introduce the so-called Schroeder frequency, named after the German physicist Manfred Schroeder. The Schroeder frequency denotes the crossover frequency between the chaotic behaviour of sound waves above it and the discre... | |
| Room acoustics I have to sign off now (it is evening where I live) because I am expected at a birthday party. Please continue. | |
| Room acoustics OK, maybe we need to look into that then, because graphs are very illustrative of potential problems. Most telling are waterfall graphs, as these show that peaks also linger on. If people talk about slow bass performance of a speaker/sub they are ... |
