| Scratched woofer surround rubber No. Most of the suspension is in the spider, not the surround anyway. | |
| Luxman 509 or McIntosh 8900 @deadhead1000That's my experience too, but my time with Mc is so short I hesitate to say anything. What speakers were you listening to with each though? | |
| My room has "zero" slap echo. Do I need room treatments? Without measurements, the best advice I have for you is to listen to your speakers 2’ away from them. The difference between that and your normal seat is your room. Best,E | |
| If I upsample digital flac 16/44 to hires 24/192 is the sound equal to native 24/192 It all depends on what device or process you are using to upsample your music.No, not really. No upsampling algorithm can reproduce harmonics as in the original session. They can however improve the frequency response and jitter performance of t... | |
| Measuring line noise and power conditioners In your recent responses, you say RFI. We are referring to EMI.My bad. What I hear ain't luck. Having a device that can measure what I hear ain't luck. Coincidence and bias are real, which doesn't mean you haven't done enough experimentation to... | |
| Male to male XLR question OP:That’s the convention. The pins point to the destination, so outputs use male, inputs use female. Makes stringing large numbers of cables together a lot simpler in a professional environment where you have mic and amp runs. | |
| Series Mode - Licensees The only reason not to buy SurgeX seems to be I can't tell if they are in business or have been folded into another org. | |
| Measuring line noise and power conditioners My point to all of this is that cleaning up AC noise in the audio frequencies is as important or more than RFI. We should be looking at devices and measurements which clean up both. Think of most power conditioners as essentially filters, much lik... | |
| Measuring line noise and power conditioners It’s hard to imagine noise on your line only affecting one portion of the frequency range. So in other words if you reduced noise that’s being measured above 20khz why wouldn’t you expect that same filtering to affect the entire range even in area... | |
| Measuring line noise and power conditioners If we are talking about this meter:https://www.alphalabinc.com/product/plm/You are measuring starting at 20 kHz and going up. That is, these devices START measuring noise at the upper limit of human hearing. While many surge protectors claim to b... | |
| If I upsample digital flac 16/44 to hires 24/192 is the sound equal to native 24/192 Hey Sam,If you upsample from CD you cannot get more data. The Zero Order Hold filter looks like a really bad idea compared to Bezier curve models. You are adding odd order harmonics due to the square nature of the sample reconstruction. So, you ... | |
| Need to upgrade speakers Keep the Luxman, but get brand new speakers. Don’t go vintage unless you like to DIY. The turntable and tape players really depend on how you listen to music, and how you want to collect it. Right now I'd suggest you go all digital with a streame... | |
| Power strip question This comes up so often that I wrote a blog post and put my thoughts here:https://inatinear.blogspot.com/2019/04/power-management-for-frugal-audiophiles.htmlBest,E | |
| How Does a "HI-LEVEL IN" Affect Impedance Load? Sub speaker level inputs are usually in the range of hundreds to tens of thousands of Ohms. So, doing the normal math for parallel resistance (which is close enough to impedance for us to illustrate) :R = 1 / (1/8 + 1/10000)where 8 is the speaker ... | |
| Why does a Music Server require high processing CPU power? Here, take a look at the GNU gzip code:https://savannah.gnu.org/projects/gzip/That may help you understand. Every instruction takes CPU time. The faster the CPU, the less time that instruction takes. Best,E |
