| Class D amplifiers. What's the future look like? Speaking of bass and guitar players, with tubes you can tune and fine tune the sound by tube rolling. And with SS, any class ? @inna Many guitar and bass players rely on their effects 'pedals' to sculpt their sound. So a lot of the time they ju... | |
| Class D amplifiers. What's the future look like? I wish my ears were more forgiving. I think I could make some Class D work for my ears with tube line stages and dacs, but, i really don't want to deal with the confoundedness/pestilence/mainteance crap with tubes anymore... @deep_333 @inna I ... | |
| Class D amplifiers. What's the future look like? @deep_333 I've seen that list of quotes before. They got debunked due to their age. A lot of those quotes you listed are from nearly 20 years ago. At that time I was of the same opinion as seen in them. One way you can date the quotes: look at ... | |
| Annoying trend? New vinyl equalization and compression @mahler123 The radio stations have their own compression they've used for decades, even back in the 1960s. I don't doubt Colombia was using compression though. I was commenting on much more recent releases. | |
| Class D amplifiers. What's the future look like? Why is there this "push" to Class-D in the first place? What do you gain? In what way would they ever be sonically better than a good Class A or AB amp? @moonwatcher Class D offers something that is very hard to achieve with A and AB amplifiers... | |
| Annoying trend? New vinyl equalization and compression I doubt that Technics is selling all their new turntables to just the high end market. When we were mastering LPs for a digital source file, we would try to make sure that the file had no DSP other than normalization. In that way we could master ... | |
| Class D amplifiers. What's the future look like? They will go the way of cd players, in ten years no one will need them. Ralph and others perhaps have some time to cash in. He does not prefer his class D to his and many others tube amps. He won't fool me. @inna I don't think if I was trying t... | |
| 300b lovers If you do direct-coupling correctly, it can be very reliable. I don’t think it wise to direct couple throughout the circuit though! The advantage of a direct-coupled cathode follower driver tube are several. First, there is more current available... | |
| Annoying trend? New vinyl equalization and compression Compression is used because it takes less time to engineer the LP side. You just start the source file (or tape) and let the cutter do its thing. You might spend 4x as much money if you don't use the compression, trying to sort out how to cut the... | |
| Preamp for a GaN-FET amp... It would seem that while tubes have the preferred distortion ratios, their total distortion is higher than all solid state preamps. So, what is it that is creating this preference and is this something that solid state preamps can "copy"? @sna... | |
| Preamp for a GaN-FET amp... then why isn't GanF also the future of preamps. @snapsc The issue is technical. The issue is something called Gain Bandwidth Product, which is important in amplifier design, if that design is using feedback. With conventional solid state and tu... | |
| Can a tube short without blowing? Can a tube short without blowing? @txp1 Yes. Usually when you get a pop, its the tube arcing, often due to an internal short. But it might check just fine after that, or it might be dead or anywhere in between. Its a pretty good bet the tube wi... | |
| 300b lovers They now dominate high-end audio, which was not true thirty years ago. I remember going to some CES shows with hardly any tube amps at all, never mind DHT’s, and now they are everywhere. While it is correct that there are more tube amplifier pr... | |
| 300b lovers Nice article! Too bad direct coupling wasn't tried. That would have been fun to see. | |
| Help and opinions needed on pre-amp situation The Lumin S1 was their top of the line/flagship offering prior to the X-1. In the menu it has a setting for "Analog Output Level" and has "Normal" or "Low" for choices. Not sure if that has anything to do with what @atmasphere Ralph mentioned abo... |
