| Woofers going crazy when playing vinyl I would check with VPI and see what they think of the effective mass/mechanical resonance issues with regards to playing that cartridge in your arm.The mechanical resonance should be between 7 and 12 Hz, if its off, you can get crazy woofer pumpin... | |
| Why not horns? Well I can't be the judge of that- I have no idea what the waveform looks like once its in the air. But compared to a pile of speakers that are supposed to be pretty good at that sort of thing I don't find good horns to be lacking. I find bad horn... | |
| Listening off grid with batteries You might also consider setting up a wind turbine to supplement the solar. Most of the people I know that run solar though have come to rely on the panels alone though, as there are no moving parts.As to the system, Getting the most efficient spea... | |
| Why not horns? Unsound, what do you mean by 'waveform integrity'? Is this in the circuit of the speaker or is this the output, etc and how does this relate to phase angle, if it does?I'm pretty sure that Duke is trying to get the best fidelity out of his speaker... | |
| Balanced vs Unbalanced? Koegz, in a nutshell, that is the whole point of balanced line operation. The system was created to eliminate interconnect cable problems.There is a standard that has to be conformed to in order for this to be true. If the conformance is not there... | |
| Balanced vs Unbalanced? OK Herman, yeah maybe a little, or maybe more than that :) But really, its pretty easy. If you drive the cathode of the input tube rather than the grid you have what is called a grounded-grid circuit. You need a coupling cap to do it. Turns out th... | |
| Designer Hall of Fame Yeah, a Clint Eastwood with lazers!! I understand he demonstrated a high power lazer to a class that he taught, punching a hole through a brick wall. The next day supposedly the FBI showed up and classified it. | |
| Balanced vs Unbalanced? Herman, Yes, that's true. I've found in practice though that it does not seem to come up. Also, again the CCS circuit plays a huge role in this- even if there is a mismatch in the tubes, you don't seem to get any extra noise.BTW, any tube amp with... | |
| Why not horns? One thing that Duke did not cover is the drivers in use in the horns. Many speakers have breakups which contribute to distortion; if a horn driver exhibits this the result can be really bad. I know of at least one driver that has no breakups in th... | |
| any audiophile guitarists out there? Kijanki, I used to play out with bass a lot. These days, I play out with keyboardshttp://www.myspace.com/thunderboltpagodaThe tracks on the myspace are from live shows a few years ago. | |
| Balanced vs Unbalanced? Herman, look at it this way: a differential amplifier does not care if it is getting a single-ended or balanced input signal. It will act exactly the same in either case. So if the input signal has two opposing inputs that have slightly different ... | |
| Does "perfect alignment of cart" eliminate 100% ? Some arms are more affected than others, yes. Mistracking in the inner grooves might also be caused by the mechanical resonance of the arm/cartridge being slightly too high.Electrical loading of the cartridge can help too.Some preamps will exhibit... | |
| Balanced vs Unbalanced? Rleff, it really depends on the speaker rather than the technology. Its the 'all else being equal' part that prevents an answer beyond that. Either one can be awesome or suck really bad. | |
| 6922 6DJ8 or 12 AX7 tubes better for preamp? 6SL7s have similar gain to 12AX7s. IME they are often prone to microphonic issues and so have to be very carefully hand-picked. Of course in a LOMC phono section *all* tubes must be picked for low noise. It is this reason why truly quiet NOS tubes... | |
| 16-ohm driver question Yes. If your amp was set up for 16 ohms, the output transformer would have less distortion. That translates to greater transparency and smoother sound. You will also get a little more power. |
