Rumbly feedback
Hello fellow A'goners. About a year ago I set up a wand 10.3 on the pedestal they sell as my turntable (brinkmann bardo) does not have an option for a second tonearm. Overall, I'm extremely satisfied with the performance. It has an ortofon Winfeld Ti mounted on it and the detail of the cartridge mates to the musicality of The tone arm is a truly magical match. Recently though, I've been listening to a bit more bass, heavy music and a couple of recordings that are mastered at very low levels. When I play these recordings at moderate volumes I get an intermittent bassy rumble that seems to come through. If I turn the volume down it dissipates and additionally, if I place my first two fingers on the pedestal, it goes away immediately. This rumble does not occur if I use my other tone arm which is the brinkman 10.1 with a custom vas cartridge mounted on it. I'm wondering if anybody has any ideas on how I could dampen the pedestal some to try and avoid this feedback.
@dogberry I think that's exactly it. As I said, when I press down onto the pedistal with just a little force the rumble goes away. It's like if I brace it to the HRS platform a little better it solves the problem. I wonder if a heavier pedestal would solve the problem. @mulveling I think the problem is more the last thing you mention, where the woofers are sort of flapping in a pattern and it's audible. What do you mean by rack bracing? |
@mulveling I think I have pics of my system in my virtual system. It don’t have a big tall rack. I have a lower solid walnut custom piece that weighs a ton. I dont thing it’s flapping from that and, as I mentioned, it’s only the tonearm/cartridge combination mounted on the pedestal, the tonearm attached to the turntable does not have this problem. I’m wondering if bracing the pedista to the HRS platform might solve it since when I press on it it goes away. I just ordered some very long Velcro straps to do this. We’ll see what happens! |
