| AUDIO PRICE INSANITY PRICE VS. PERFORMANCE WORTH IT? Calvinj - I downscaled from a large Krell /Dynaudio system to an OTL tube system, and for me, this works great. I have looked for used quality components and upgraded from there. It is sad that part of the audio gear becomes over-priced, but it is... | |
| Why are my woofers pumping? Since the problem is mainly gone, the thread should end soon. But it would be nice with a conclusion. I had woofer pumping, I changed some things in my system, and then the pumping (or most of it) went away. Why? Not clear. Maybe the most likely r... | |
| Why are my woofers pumping? Resonance - a red herring? If so, reducing effective mass on the SME V may not be a good idea (+1 to Atmasphere, and others, for setting me on this track). Therefore I thought, OK, let me go back to a normal setup of the arm. I screwed the upper b... | |
| Why are my woofers pumping? Tighten the center shaft - meaning: the housing of the spindle. cleeds - thank you, yes I bought the Atlas new and it shows no obvious signs of wear so far. You are right, it may be a spindle / bearing problem. So I want to eliminate this factor.... | |
| Why are my woofers pumping? Before going on, I need to tighten the center shaft (with the magnets) to the plinth on my Hanss T-30. It is fastened by four screws from the underside of the plinth. Does anyone know the type and dimension? The screws are very hard to see unless ... | |
| Phono stage I would like to correct a rather broad statement I made above. The Aesthetix is very quiet with the best low noise tubes. These are not very expensive (new production). Even with somewhat worn (but wonderfully musical) Telefunken NOS tubes in the ... | |
| Why are my woofers pumping? Han_n - yes I will test this more. The "low cut" option may be what I lack. Toddc2 - thanks, I have followed up. I mailed an audio tech the other day, is it likely my woofers are getting worn out? Even if I don't hear clear problems? Answer: afte... | |
| Why are my woofers pumping? Thanks, all! I think we can conclude that1) the Atlas / SME V combo is very “receptive” in the lowest frequencies, and that in some resolving systems this may give unwanted effects like woofer pumping. 2) this is mainly a resonance problem, not a ... | |
| Why are my woofers pumping? There must be other Lyra cartridge / SME V owners out there, who have or don't have woofer pumping - ? Would be nice to hear from you! And maybe J Carr from Lyra could give a comment?Atmasphere's advice reminded me of the old trick with the SME V ... | |
| Why are my woofers pumping? Invictus005: I've tried your suggestion now, holding the plinth, but it makes no difference. This is a very heavy player (83 lbs). I used the runout on the Hifi News test record. And noticed, once more, that the woofer pumping is much reduced, com... | |
| Why are my woofers pumping? tzh21y - yes I think the same. Maybe even small things help, getting the resonance up. Stripping the arm of all extra mass and changing the counterweight position, like Atmasphere suggested. Invictus, Almarg - I don’t think the player is the probl... | |
| Why are my woofers pumping? Thanks, all! Great to get so much expertise input!Cartridge is probably OK, not worn, no sign of wear, or mistracking. Like I said, it is not the Io phono stage, since when the stylus is lifted from the groove, the woofers stop pumping. I have tri... | |
| Why are my woofers pumping? Thanks, Raul. I will test some of your suggetions - platter mat - and report back. But like I said before, it seems very basically "physical" - it happens before eventual mechanical turntable etc problems. | |
| Why are my woofers pumping? From the A-gon opinions so far, here, such examples are not very interesting. It seems that the SME V can work OK with the Atlas, but it is not the ideal arm - ? I will look for other cart / arm combinations, when my current one runs out, and I ha... | |
