| Audio Horizons fuses.... won’t buy them again... I am done George.... No more... About time. | |
| Audio Horizons fuses.... won’t buy them again... Oh well......Try this type of slo-blo fuse in your power amp/s. It has built in wiggle room. Still confused, and testy as well.Then you should have directed this directly at the OP, not just as general comment at me or anyone’s amp or amps, to gi... | |
| Hypex N core module FWIW the squarewave response you linked does look pretty bad. Our tube amps can do better than that! Of course it can, any linear amp can, not just yours! It’s very good for any Class-D without the need of special external output test filters.htt... | |
| Hypex N core module Now the parts we work with are not that expensive, but we found a way to eliminate deadtime. This allow us to switch at much higher frequencies. Naturally your not going to tell us how it’s done, I’m hope for you that you can do it, but also scep... | |
| Hypex N core module Now the parts we work with are not that expensive, but we found a way to eliminate deadtime. This allow us to switch at much higher frequencies. Ralph, what is the approx ringing of the square wave I linked to in the 1st pic, it is the switching ... | |
| Hypex N core module Here is an example of today’s switching frequency trying to be filtered by Mark Levinson No.53 with the $50k usd Class-D. They tried very hard by as you can see by the 4 massive x filter chokes added together (paralleled or series or both) to give... | |
| Hypex N core module Several MHz isn't a problem. We're working with inexpensive devices that can easily do 5MHz and beyond. Technics have produced a Class-D amp (SE-R1) that has double today's switching frequency speed so the output filter has less of a chore to ... | |
| Hypex N core module Here are the 10khz waves of Class-D both done by Stereophile tests, one with and one without the Stereophiles special AUX-0025 passive low-pass low power filter. This filter can't be used while listening as it would burn out almost instantly.Wit... | |
| Hypex N core module The filter can do its job properly at current frequencies. There is an advantage to going to faster switching frequencies- lower distortion. Sorry this is not correct, that is why when Stereophile do their bench tests they have to use a very spec... | |
| Hypex N core module mitch2 I have no idea whether my impressions are related to the switching frequency George describes, but they could be. I owned and used in my main system a pair of the Acoustic Imagery Atsah monoblocks made from Bruno Putzeys' highly rated... | |
| Least expensive discrete resistor ladder NOS DAC? More Soekris filters here, including the "near NOS" one as well.https://hifiduino.wordpress.com/2015/06/27/r2r-dac-benchmark-filters-for-now/ Cheers George | |
| Audio Horizons fuses.... won’t buy them again... You’re drifting from the subject. No, sorry, your confused. Try this type of slo-blo fuse in your power amp/s Never ever do this if the manufacturer hasn't used it, or you may cook many components, instead of a couple if it goes faulty.Cheer... | |
| Least expensive discrete resistor ladder NOS DAC? nitewulfThe Schiit and Soekris dacs aren’t NOS dacs, they are r2r but oversampling.I know the Schiit isn’t NOS, but from what this seems to say, the Soekris has many user sellectable filters, and NOS mode is just but one of them.Soekris Filters:"... | |
| Audio Horizons fuses.... won’t buy them again... For all I know it is a picture where the fuse was subjected to an overloaded condition beyond its’ ampere rating for a period of time. Believe what you want, next time you switch on a high current draw amp, see if you can see the resistive elemen... | |
| Info wanted on Krell KMA 400's steffo Info wanted on Krell KMA 400’s Don’t believe for one minute they are 400w Class-A, having the 400 figure, they would have been conservatively rated at 400w Class A/B into 8ohms, bench tested usually a Krell will be more, like 450-500 Class... |
