| A Few Turntable Measurements using the RPM Android App @terry9 There is a well-defined method for measuring wow and flutter and rumble, which only differ in frequency and source, but not in nature. This method turns out to be quite complicated. Whether the RPM app developer used this method or not is ... | |
| A Few Turntable Measurements using the RPM Android App @rauliruegas Hi, Thanks for the link. Surprisingly, the wow and flutter reported for the Double X by the author of the article you referenced is the same as the wow value I reported above for the AS WOW XXL using the RPM app. This result is encour... | |
| A Few Turntable Measurements using the RPM Android App @brev Yah, it is fun making these measurements. I wish that the developer would publish his/her methodology. For example, what algorithm is used for the WOW calculation? Is it one of the standards? I don't think we'll find out any time soon. Apps... | |
| A Few Turntable Measurements using the RPM Android App @mijostyn The belt is brand new. Just put it on about a month ago. The old belt had stretched. The measurements I reported using the RPM app were done with the new belt. I was shocked by the poorer performance of the WOW. Acoustic Signature does... | |
| A Few Turntable Measurements using the RPM Android App @terry9 Like with many quantities, the speed aspects of turntable rpm can be described as a mean surrounded by skirts on either side. I say this with trepidation, because the turntable noise is not a stochastic (random) phenomenon. It can have res... | |
| A Few Turntable Measurements using the RPM Android App @lewm I have not been able to find specs on the Nottingham or the Walker tables. It is quite difficult to make comparisons on table performance without basic speed and vibration specs. I will never buy a table again without seeing these specs. On... | |
| A Few Turntable Measurements using the RPM Android App @ossicle2brain My Acoustic Sounds WOW XXL table is an excellent case. From a cold start, it needs a push on the platter rim to begin spinning. One never knows when it is up to speed. There is no feedback. The REW app provides some idea. The app h... | |
| A Few Turntable Measurements using the RPM Android App @duckmanst3 Hi, I'm not questioning the accuracy of the hardware, although that would be nice to know. I'm concerned about the logic and math used to make the calculation. That info has not been published and probably won't be because (I bet) the ... | |
| A Few Turntable Measurements using the RPM Android App @ossicle2brain One way to find out how much weight is too much is to add weight to the table, then measure the RPM and WOW with the app. Continue to add weight until the speed changes or the WOW increases. This will probably happen before anything... | |
| A Few Turntable Measurements using the RPM Android App I should point out that the RPM app has not been independently verified for rpm accuracy. As I reported above, the repeatability is good. The WOW 2 sigma reported by the app has also not been verified. In particular, the method of calculating the... | |
| ZYX "House" Sound @rauliruegas : Thanks for the discussion. I've learned a lot. I appreciate your patience with me. I am looking at the Technics SL-1200 G and GR. The prices are reasonable. Performance looks exemplary. I come from a technical background - Optics, ... | |
| ZYX "House" Sound I do use the resonance calculator. I always check before installing a cartridge. I have a number of headshells and weights, so I can tailor the mass to obtain resonant frequencies between 10 and 7 Hz. That is, if I know the arm's effective mass. I... | |
| ZYX "House" Sound @lewm That is the slyest compliment I've ever heard. Gave me a chuckle. Thanks. I do agree that the components with moving parts will affect the sound and sound a bit different as they age. I consider speakers, phono cartridges and the listening... | |
| ZYX "House" Sound @rauliruegas The Technics Sl-1200GR you post a link to has grabbed my interest. It does look like there's a lot of value for a very reasonable price. Thanks for the reference. Will the Koetsu, the Shelter and the ZYX cartridges shine on this tab... | |
| ZYX "House" Sound @rauliruegas Thanks for showing me the Technics table. Very good example of good value. If I didn't already have four tables, I might seriously consider it. I don't use the Denon as much as the DD-40, primarily because I don't like the look. The ... |
