| Why are my woofers pumping? The interesting thing is: it happens at certain intervals per revolution of the record (playing silent grooves between tracks). If I turn up speed to 45, the pattern is repeated, only faster. This seems to indicate that player rumble or drive prob... | |
| Tube pre-amps: balanced a big deal? Balanced is great for long, long runs, otherwise for typical in home usage you wont notice anything else besides the free 6db gain. This statement is problematic. Many balanced systems don't give you any extra gain. The real reason that balanced ... | |
| How much do I need to spend to get a preamp that sounds better than no preamp? George excerpted a quote from Nelson Pass's website. It makes it look like Nelson had a certain position on the subject, but if you read what follows, you might see that such is not the case. Here is that further text (I've included the end of the... | |
| Contemplating DEVORE SPEAKERS (and others)....LONG audition report of many speakers The Devores are an excellent speaker, but if you really want to hear what they do, use a tube amplifier. They are a great load for tube amps and they don't need a lot of power- I recommend 30-60 watts as a minimum in most average rooms. | |
| Why are my woofers pumping? Based on Atmasphere's advice, I also tried higher loading, going from 475 ohm to 121 ohm (not so easy on the Io, changing a jumper at the back). Result? Musicality: great. "Echoes" sounds a bit sweeter, more mellow. I realize, I am moved by the... | |
| Why are my woofers pumping? OK... what do you want to know? | |
| Why are my woofers pumping? @invictus005 To which part do you address the 'huh'? | |
| Why are my woofers pumping? @o_holter A simple way to decrease the compliance of the cartridge would be to load it. I would try 50-100 ohms and see how that works out.Its not a sure bet- if you load the cartridge too low, its output will decrease, and in turn you phono pream... | |
| Why are my woofers pumping? @o_holter Raul's suggestion that the cantilever suspension is failing could be an explanation, but the problem I have with that is the cartridge must be pretty new so this seems really unlikely.I looked at the specs of the ARC used in the review; ... | |
| Why are my woofers pumping? Atmasphere - you may be right. But Lyra does not warn, and web debate does not complain, using the Atlas on the SME V - so i wonder.It might be that some of those debaters don't have the bottom end bandwidth in their systems that yours has.I went... | |
| Why are my woofers pumping? Your cartridge has a compliance value that is too high for your arm. You could reduce the effective mass. That can be done with different weights on the counterbalance (a heavier weight, closer to the fulcrum), lower mass arm or a lighter cartridg... | |
| Phono Preamps with "balls" ? It could be a good alternative in your designs instead the out of production devices you were using.We don't use any out of production devices. We have an internal design rule called the 20-year rule that prevents us from doing something like that... | |

| A Question on Speaker Driver Efficiency This is exact quote from cj1965 post:In theory, half the voltage applied to a driver will result in half the sound pressure in the output (-3db). Res ipsa loquitur, huh?Obviously he didn't actually do the math, but based this on belief instead- th... | |
| Decware and SET Low Power Tube Amps with Hi Efficency Speakers Both the Decware and the ZUs respond well to a little more power than most SETs can provide. A lot depends on the room- how lively, how large, how close you are to the speakers, and your own tastes.One dealer of ours was using our MA-1s (140 watts... |
