| 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... | |
| Purifi Class D: Junk? I can't agree with this statement Atmasphere, it really depends on the power supply, how it was designed, and circuit limitations.Most switch mode power supplies for power amps I see for audio are not power factor corrected. They tend to be sin... | |
| Best cost no object tube phono Btw, I named my personal unit Essential 3180 because it has at least two important upgrades from the 3160. All those customers are satisfied with.And you know what: unfortunatelly you will never have the experience to listen/own the 3180. You c... | |
| A question of loading... You are showing your ignorance Dover. 47K is not standard for a MC and not standard with the Etna Lambda, which I am listening to as I type this. 47K is the standard for MM. Not for MC. Actually 47K is the standard input impedance for all phono ... | |
| Purifi Class D: Junk? Take it up with the likes of D’Agostino, Curl, ect ect manufacturers of the greatest amps that are recognized as being able to drive speakers with loadings that make Class-D’s run for the hills, they will tell you the same thing.Actually they w... | |
| I have been wanting to try using a tube amp. Looking at the speaker and its specs you'll need a pretty powerful amp, although a lot depends on your room. As far as I can make out (Focal is pretty precious about what specs they are willing to publish), this speaker is four ohms in the bass an... | |
| Purifi Class D: Junk? Show us just one that’s not, and can almost double it’s rms measured wattage from 4ohm to 2ohm. The true indication of not current limiting, like many good A/B bjt amp.George, seriously, you would do yourself well to educate yourself on how amps... |
