| Woofer pumping possibly due to tube amp when playing vinyl @ last_lemming, What cartridge(s) are you using with the Prime? It's a good chance that someone reading this thread may have the same combination and they can check to see if they are having a similar issue. | |
| Woofer pumping possibly due to tube amp when playing vinyl Should have mentioned that there is a resonance calculator on the Vinyl Engine site that can be used to estimate resonance based on the effective mass of the tonearm, compliance of the cartridge and the weight of the cartridge/hardware. No substi... | |
| Woofer pumping possibly due to tube amp when playing vinyl Very good advice from @atmasphere. Many records are available that have tracks for testing both lateral and vertical resonance of an arm/cartridge combination. Certainly worth measuring if you haven't already. | |
| Update on Audiogon Member Almarg I can't count the number of times I've scrolled through long threads on Audiogon only stopping at the almarg posts to help me separate the wheat from the chaff. His contributions were always informative. But, more importantly, they displayed a p... | |
| Woofer pumping possibly due to tube amp when playing vinyl The operable range of the speaker is usually described as the range in which it will reproduce sound, which is why a +/- dB specification is the norm. That doesn't necessarily describe the range of frequencies that the speaker can physically resp... | |
| Woofer pumping possibly due to tube amp when playing vinyl @ last_lemming, have you measured the vibration at the turntable platter directly? I have an app on my phone that will measure vibration on a surface in the X-, Y-, and Z-axes. It might be instructive to get some sense of the magnitude of any di... | |
| Sub Sonics and woofer pumping Given what you’ve said about the rumble being worst in the lead in groove it would be worthwhile to try a periphery ring. I use one and it is very beneficial in terms of vertical movement of the record. | |
| I underestimated the impact a new cartridge would have "I started out in the 1960s and ’70s with MM cartridges including a top of the line Shure V-15 @kayleerex1 V15 wasn’t even a top of the line from Shure :)Top of the line is Shure ULTRA 500 Series"Ultra series Shures were introduced in the '80's. ... | |
| One Channel of Magnepan Mini Maggie sounds lower than the other The mini maggies are dipoles and very sensitive to position. Were the speakers they replaced also dipoles? Is the proximity of the left and right channel mid/high panels to the walls similar (e.g., is one much closer to a wall or corner than the... | |
| What do/did you do for a living? "Not top tier, but sure puts a smile on my face." Sounds your system is doing EXACTLY what it's supposed to do. | |
| What do/did you do for a living? Neuroscientist. Have studied visual, auditory and infrared systems at the cellular, subcellular, and genetic/molecular levels. Most recent concentration on neuroimaging (mostly functional magnetic resonance imaging - fMRI) the developing human b... | |

| In Defense of Audiophiles, Bose, Pass, Toole and Science Good analogy whoopycat. We should continue to investigate the nature of audio reproduction, perception, and appreciation. Certainly, at this point in time all of the meaningful measures have yet to be defined and curiosity about what is missing... | |
| Finally took the Bryston 4B Cubed plunge professorsvsu - congratulations on your 4B-SST3. Bryston makes excellent equipment and is an outstanding company. I agree with the synergy between Bryston and Audio Research. I have a 4B-SST2 that is paired with an LS28 preamp and I think it is... |
