Open up your phono, line, and power amps and you'll see all sorts of "filters" such as transformers, resistors, capacitors, chokes, etc. It seems to me that the audio signal is always necessarily "filtered" once that stylus and its motor assembly picks it up off the record surface. Sorry, but that's not very convincing to me. Sounds like you're simply repeating your analog rhetoric without much scientific knowledge on the subject to back it up. This is your response? I thought you knew what you were talking about. It's obvious that your music/sound priorities are different from mines that are to lose or add the less to the cartridge signal protecting its sensible integrity to be nearer to the recording.ĭear Actusreus: probably you don't know how filters works so take a look on internet to learn about other that what Onhwy61 posted. You like aspirns: good, nothing wrong with that. I don't like to take an aspirin for a headache but is better to know why that headache coming and then fix it. If any one of us has a problem with those woofer movements and the system set up is correct then something on the audio system links is running wrong or exist a mistmatch in between or simple bad design item and in this case we have to change it. I would like that you can explain how is that a cartridge signal that pass for a rumble filter that is an additional electronic stage is not degraded ? IMHO the best rumble filter is NO rumble filter, especially that in normal condition we don't need it. Now, maybe I'm ignorant on the subject or I'm missing something or you know for sure something I don't. I'm not against your prefrence because you are satisfied with and is you whom have to live hearing it. With all respect all those satisfied owners of rumble filters are ignorant of what I'm posting here.ĭear Hdm: I think that if you take 10 persons with the experience you have and ask about their preferences on use a rumble filter or not use it you could get 9 answers that they don't use it and don't like it ( me between them. Of course that a filter seller always will tell you that you need it because that's how is taking money from you. The audio signal does not needs to be filtered to avoid those woofer movements what that is telling you is that you have a problem in your system set up and that it's. Forget about rumble filters or any kind of filters. I repeat all resides to have a right overall system set up. ++++ " So I am wondering why dont a lot more companys sell these things if they are so important? " +++++īecause is no important as you can think. What we have to do is to revise the overall system set up to find out where it comes the feedback that makes the woofers moves. Do you have a Rega dealer local? Can you ask to borrow a RP3 (either the whole deck or maybe the glass platter) to see if it reproduces the woofer pumping? Does anyone know if acrylic platters are prone to reproduce more woofer pumping (I thought they reduced vibrations) as the Xpression III and Matt's P3 both have acrylic platters?ĭear Mattmiller: If we take care on the overall audio system each link set up usually we have no need for a rumble filter.Ī rumble filter as any filter where the audio signal pass always degrade that signal in many ways and IMHO do more harm than help. I am using the factory RP6 subplatter and glass platter, but I just ordered a GT RP6 reference subplatter. Since you are using a Rega P3 with GT upgrades (I assume subplatter and acrylic platter), I'm not sure where to turn on this. I sold the Pro-ject gear and did not look back. Once I upgraded the table to a Rega RP6 with same cartridge, same wall shelf and same Jasmine LP2 mkII, the woofer pumping was gone. I uses an Ortofon MC-3 turbo on the Xpression III. I got woofer pumping with both preamps (the Pro-ject phono tube box had a subsonic filter, tried it in both postions, the Jasmine does not have a subsonic filter). I tried both a Pro-ject phono tube box and a Jasmine LP2 mkII for phono preamps. I had woofer pumping with my Pro-ject Xpression III.
