| are some phono stages more resistant to hum? Lloyd, have you tried temporarily using a cheater plug (a 3-prong to 2-prong adapter) to isolate the safety ground pin on the power plug of the phono stage and/or the turntable? That would break a ground loop between the two components, and enable... | |
| General comments on SOTA This thread from a couple of years ago addresses your question. As might be expected, opinions are diverse.Regards,-- Al | |
| DAC w/ low-voltage XLR analog outputs for EMM XDS1 RGS, have you considered simply putting a pair of balanced in-line attenuators at the inputs of the headphone amp, such as those made by Rothwell. Here is further background.10db of attenuation would reduce the 5 volts to about 1.58 volts. 20db wo... | |
| Preamp or power amp has more impact to resolution? If the source and preamp are unable to deliver the goods there is nothing you can do about it downstream.On the other hand, if the power amp or speakers or room acoustics are limiting the resolution of the system, you can't do anything about it up... | |
| Fuses that matter. Geoff, I would put it that all of the technical rationale, technical data, and technical speculation that I have seen offered to explain the claimed benefits of expensive fuses, and Bryon has done a particularly noteworthy job of unearthing much o... | |
| Why is the market for used Levinson amps so slow? Levinson wasn't the engineer who designed the components; that was Tom Colangelo, who went on with Levinson to form Cello. Levinson isn't a EE, he's a musician / recording engineer sort of guy.Levinson the man moved on from Mark Levinson the compa... | |
| Fuses that matter. Hi Bryon,A diode will conduct current when the voltage at the terminal FROM which the arrow is pointing is greater (i.e., more positive, or less negative relative to some reference point) than the voltage at the terminal TO which the arrow is poin... | |
| Fuses that matter. Hi Bryon,Thanks once again for providing the reference. I applaud HiFi-Tuning for providing these measurements. However, IMO they provide the basis for a good case as to why fuse upgrades shouldn't make a difference, or at least a difference that ... | |
| Would like USB ADC w/ input level control You might want to consider a completely different approach, which would allow you to eliminate the computer and the digital noise it generates from the a/d conversion process.That would be to purchase a portable digital recorder, that records onto... | |
| Fuses that matter. Hi Bryon,Just to clarify, I think that in number 3 you are referring to other fuse-related variables, perhaps unexplainable ones.Also, where I referred to rectification, filtering, and in some cases voltage regulation as reducing the magnitude of ... | |
| Fuses that matter. 05-12-12: BryoncunninghamThere's a guy over on the Polk Audio forum who claimed his measurements corroborated both that fuses measure differently and that even fuse directions measure differently. You can see his measurements here. I don't really ... | |
| Fuses that matter. 05-12-12: GeoffkaitAs a skeptic, don't you think truth would be better served by actual investigation rather that idle speculation from the comfort of your Barko Lounger? You might consider taking a tip from PT Barnum who said, folks would be bett... | |
| Fuses that matter. Geoff, let me pose a simple question. When a seemingly absurd claim of sonic benefit from some tweak is offered, do you consider that there can EVER be a finite limit to its apparent degree of absurdity beyond which it is justifiable to dismiss th... | |
| Fuses that matter. Since the scope of the discussion seems to be broadening somewhat, I'll make a couple of general observations about differences that are alleged but that seem to have no rational basis, or at least no rational basis that is quantitatively supporta... | |
| REL subwofer High Level vs Low Level connection Ryriken, I suspect that you mean that he says to use the main speakers full range, as opposed to high pass filtering their inputs (i.e., filtering out the deep bass content of the signals that are provided to them). That's a different question tha... |
