| Need suggestion on tube amplifier with XLR inputs What is the cutoff frequency of the sub? That will make a big difference as to how much power the mids will need. Can you rearrange the drivers in that box so that they are in series? | |
| Duelund Capacitors?? Steve, the resulting value is defined by the formula C1 x C2/C1+C2 , in this case about 0.45uf. BTW this is the same formula for resistors in parallel. | |
| Loading Tube Equipment for Audition/Comparison Your understanding of preamps is correct.If you have no input on an amplifier, generally you won't need a load on it either. The best way to accomplish that is with a shorting plug on the input so there is no possibility of a signal.Some amps are ... | |
| Need suggestion on tube amplifier with XLR inputs If you have 3 midrange drivers in each channel I would put them in series since you have an electronic crossover- that will make them easier for a tube amp to drive. However Jim and Spencer are both making good points- getting the system to blend ... | |
| Symdex speakers any information on these? Hi Lee! Its good to hear you are still around! You may recall that we showed together at CES back in the early 90s.All the Best,-Ralph | |
| impedance vs sensitivity Sensitivity and Efficiency are two specs that try to express the same thing from different points of view. The different points of view are the Voltage Paradigm and the Power Paradigm, which are opposing concepts of how to design and test amplifie... | |
| Where does fatique come from? Our ears use certain odd-ordered harmonics in order to determine loudness. We are very sensitive to these harmonics; if they are altered even by trace amounts we will develop 'listener fatigue' as it was know as in the old days. Anything that can ... | |
| Please suggest good balanced Preamp FWIW, the line section of the MP-3 has 4 tubes. The MP-1 line section has 6 tubes. Either way, the tube warranty is for a year. If you are one who is into swapping tubes, then I recommend you run the unit without the cover until you have sorted ou... | |
| binding post break in IME When you disturb the wiring of an amplifier it will have to break in again before you can hear what you did. A lot of people ascribe this break-in period to the part that they installed, but it appears that a lot of the time that is not the ca... | |
| Musical full-range in the $3-4K range used? Duke sold a set of speakers to one of my friends here in town, so I got to hear them in my system before delivering them. I really was not prepared for how good the speaker was! Very well integrated, good bass extension (into the upper 20s to my e... | |
| The best phono stage out there? Jcarr , we certainly agree about that! There are so many things that have to be taken into account that any designer that focuses too closely on any one aspect may well be doing so at his/her own peril. I think, like you (I imagine), that while it... | |
| Al Stiefel of RMAF Has Passed Away Al and Marjorie have always been special to me. I've always been grateful for their work on RMAF. I was really shocked and saddened when I saw the announcement this afternoon. All the Best to you, Al! | |
| The best phono stage out there? Jcarr, while I agree with most of what you have said, and I also feel that its a bad idea to make generalizations, especially in **this** sport, I can safely say that I have yet to see a decent circuit where feedback was also a good idea. Certainl... | |
| Tube amp recommendation Hi Jax2, my point has to do with equipment matching. An SET driving a 92 db speaker is going to get clipped a lot if you listen to demanding musical passages. On a speaker like that, you would need a lot more power- 60 to 100 watts, in order to ge... | |
| Tube amp recommendation FWIW if the amp is good, its good with rock, hip hop, electronic, classical- whatever.Contrary to opinion above, the size of the woofer and the ability for the amp to control it really is a red herring. A small amp controls a big woofer just fine.... |
