| A pragmatic view of cartridge expenses / many questions First I spent on everything else, that doesn't wear out much. Then I built an ultrasonic record cleaner, and cleaned all my records a few times. Then I bought a big Koetsu.Factory rebuild costs a bomb - but, after 1000 hours, there is minimal wear... | |
| No "Room Correction" Topic option. Why? Don't forget the cost of labour to put up two layers of drywall and slather with green glue, instead of just one layer. If you're not doing it all yourself, that is.Good luck! | |

| No "Room Correction" Topic option. Why? Barts, it's actually a whole lot more than soundproofing. The thing is to make the walls rigid, so that they don't flex in response to sound energy, especially sound from the speakers.If the walls do flex, they act like exceedingly low grade woofe... | |
| No "Room Correction" Topic option. Why? Chorus, I suggest that you also consider the lights themselves. LED's and fluorescents tend to create electrical noise which can get back into your equipment - certainly through the line, but also perhaps through EM radiation.Does not apply to str... | |
| No "Room Correction" Topic option. Why? Tomic, you might like to know that both M1 and BuildSecure are low-odour, low-VOC, non-toxic substances. Unlike some other construction glues I could name. And elastomeric is only common sense in an active earthquake zone. | |
| No "Room Correction" Topic option. Why? Egan, you are absolutely right. The first thing one notices upon entering my music room is the quality of the silence. Not only are there no distracting noises, but the room has a positive quality of its own - sorry, but that’s the best descriptio... | |
| No "Room Correction" Topic option. Why? @tomic601 I used several hundred tubes of M1 caulk/glue and 20-30 tubes of BuildSecure construction glue, which is marginally stronger. Both are elastomeric. | |
| No "Room Correction" Topic option. Why? Decided against green glue and acoustic drywall. For one thing, it isn't a glue, IIRC. I had some experience with low VOC elastomeric glue, and went with modern incarnations from Chemlink.Also, I suggest a supplier of commercial/industrial special... | |
| No "Room Correction" Topic option. Why? There has been solid science done on room size and dimension at the School of Acoustics at the University of Salford.They found that MOST rectangular rooms are poor, a quarter OK, and a few are good. Look up 'room ratios', but be prepared to desig... | |
| Game Changing Tweak Bemused, have you done this experiment? What was the result? | |
| Game Changing Tweak Bemused, I think that you will find that it's a matter of degree. The equations for filters are well known, see for example a Radio Amateur's Handbook from the 50's. You will note that EVERY LRC filter filters EVERY frequency - the question is, ho... | |
| Game Changing Tweak Mijo, do I see ghosts in my closet? Not any more.My ’unit’ does not have a bad power supply - at least by my standards. The DIY power supply for my DIY amps has ripple which is lower than the noise floor of my test instruments, and calculates to b... | |
| Game Changing Tweak And that assumes clean AC power. Add a lower frequency carrier wave ... | |
| Game Changing Tweak @ladickinsonAgreed about confirmation bias. But this may be something more. Power supplies filter, yes - but as you know, it's a matter of degree, and the devil is in the details.An LRC filter removes a percentage of the ripple present in a DC sup... |
