| A question of loading... In 2018 thread where wyn posted and before the first wyn post you posted not one but twice:""" When you load at a very low value (like less than 100 ohms) its possible to reduce the cartridge output and also decrease high frequency tracking abi... | |
| A question of loading... The issue that's false is that exist mistracking when more current running through the cartridge.I don't think anyone has stated that this leads directly to mistracking. The issue is that mistracking not that cantilever stiffness. It's you who ... | |
| A question of loading... So not going with education huh? A.Porter place he was running his low impedance MC cartrige around 400-500 and when I listened to it ( I/O phono stage. ) I told him that something was wrong with and I suggested to change the load impedance to ... | |
| A question of loading... "" To claim that the loading affects the measurable frequency response of the cartridge is bogus. However, if inappropriate loading bathes the phono stage in copius amounts of high-frequency noise, it may start to distort (unless the designer... | |
| A question of loading... 47 steps in attenuators seems to be another inexplicable industry standard.@fsonicsmith That's because if you don't go entirely electronic with the volume control, its insanely expensive to get a custom switch built with the exact number of steps ... | |
| A question of loading... Ken uses a SUT that doesn't really have a lot of boost because I think he believes that as the step up increases, the loss is SQ is too great.That's been our experience too. The more stepup you use the less bandwidth you get. We regularly run car... | |
| Best cost no object tube phono @mijostyn IIRC the MAT02 used in that circuit is nla. But I think you can make a MAT12 work. Most of the frame-grid triode family (includes the 6DJ8/6922) tend to have microphonic problems. So you really have to screen them. | |
| Best cost no object tube phono Btw, atmasphere I don’t care about class D amps. I was very specific about: design of SS phonolinepreamps. Of course you don't - that would not help your argument. The bigger point here is the need to be right for the sake of it, rather than being... | |
| A question of loading... Ralph-thank you for your very polite and informative response. I apologize for my strong words directed at you. No worries- and no offense taken. But I appreciate your words.What is odd, and I am not quite understanding this part, is why with my ... | |
| Schiit Freya damage by giving it an electric static discharge on the volume knob. I still think this may be a design faultIf this happened as you say due to touching the volume control and a static discharge occurred, then yes, this is the case. Static discharges are common in the US during winter and any electronics used insi... | |
| Purifi Class D: Junk? Seems unlikely that this would be the case in both channels (assuming that's the case). Since this is a stereo amp, perhaps an issue with the power supply?I agree. I don't know how the Purifi module works, but if its anything like ours there is ... | |
| Best cost no object tube phono It's not me who needs to show it but you that are an audio manufacturer and I know you can't do it because you have not the adequated knowledge levels with SS designs.So I've been making all tube preamps for over 30 years, with two patents in th... | |
| Purifi Class D: Junk? Sounds sort of metallic, "buzz-y", which is why I want to call it a distorted sound.That can be caused by an offset problem at the input of the comparitor- if its something like that I would regard it as a malfunction. | |
| Best cost no object tube phono Raul, perhaps take your trolling elsewhere. In case you read it, this thread is about tube phono sections, not some solid state unknown as you seem to always push; the one that you have that no-one else can get; that is a cheap junk store techniqu... | |
| A question of loading... OTOH, do tubes have a distinct advantage?? I would say that they do when it comes to overall SQ, plus the decreased likelihood of overload, BUT they are never 100% quiet...at least IME. There is always some minimal hiss..and this leads me to be... |
