| Lyra Atlas experiences Hi there - an update on my Atlas experience.It has now run - maybe - 1500 hours. My model was made in 2013. I try to use it sparingly. I have no clear signs of cartridge wear, so far. It has changed tone, seems a bit more mellow now, not sure, can... | |
| Why are my woofers pumping? Status: I enjoy my SME V / Atlas combo, even with some woofer pumping and - maybe - possible distortion. Yesterday I tested Kula Shaker: K2, on LP vs Tidal digital. Result: digital = no clear woofing (as before), but poorer sound. Distortion - som... | |
| Why are my woofers pumping? One more test. Changing the connectors from the Aesthetix Io phono stage to the Einstein preamp from balanced to single-ended. Result; much less woofing with single-ended. But much poorer sound too! More flat, congested, less involving. Even when ... | |
| Why are my woofers pumping? vpi, and others - two camps in this thread, "fix the cause" or "fix the problem" - if I want to fix the cause, and change the tonearm, keeping the Atlas, although I dont have the financing to do it now - what would be a good match, with a resonanc... | |
| Why are my woofers pumping? Some more testing. The woofer pumping problem is still there, maybe a bit reduced, but not fully solved (sorry for too general statements above - I thought it was solved). It is very dependent on the record - some LPs have more, some have less. I ... | |
| Why are my woofers pumping? Thank you vpi. Always something new to learn. | |
| Why are my woofers pumping? Since this thread is getting over and finished - the woofer pumping has stopped - I will only update if I find some clue, what the problem was. So far, I have not been able to recreate it. Maybe it was caused by a troubled spindle - not quite in p... | |
| Why are my woofers pumping? Some of you have suggested that acoustic feedback may have played a role for my "woofing" or woofer pumping. This is relevant not least in a four speaker system, like mine, where some drivers are pointed towards the back wall (with the record pla... | |
| Why are my woofers pumping? Hi Raul, thanks, I reread your former post, where you wrote: "even at 100hz the Atlat compliance and effective mass puts the resonat frequency in a " solid " 8hz." I get results closer to 7hz (arm mass 10.5, screws 0.5, cart 11.6g). It all depend... | |
| Why are my woofers pumping? Correction: the Atlas has a 121 ohm load (not 100) - and sounds fine.Replacing belts - yes, new ones ordered. I will give the spindle a drop of oil, and fasten the spindle housing when I get the right tool.BTW, reading up on the Hifi News test rec... | |
| Why are my woofers pumping? The Atlas sounds real good, now, with 100 ohm loading (+1 to Atmasphere). Playing Nik Bartsch: Continuum (great sound) for example, but also older overlooked classics like Joe Walsh: No peace in the city. I love this cartridge. The woofers are ene... | |
| 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.... |
