| 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... | |
| Warm vs Revealing—the struggle for balance Anyone else doing this back and forth? @w123ale No. Whenever you have increased detail that is also fatiguing (bright and harsh), the fatigue is often the result of distortion. You know you're making progress when the presentation is detailed... | |
| 300b lovers Here is an example of direct coupling: http://www.single-ended.com/Lagarto/shishido/811A.png Is 6f6 grid load easy enough for SRPP? ECC82 can be changed for 6sn7. @alexberger It needs grid stop resistors. Its usually a good practice to bypas... | |
| Help and opinions needed on pre-amp situation @veerossi To add the phono section to the MP-3 is inexpensive if its ordered that way. Regarding sound quality there are a number of variables. The most common thing you run into is that most of the balanced line equipment made for high end audio... | |
| 300b lovers With 5687 you can get even wider bandwidth especially on bass. @alexberger All tubes have response to DC. If you hear a difference with the ability to play bass, its not the tube type that's causing it. The reason we like to use 6SN7s is there ... | |
| Preamp for a GaN-FET amp... @alaindexe I get trying to move away from tubes. But I think you'll find that the common wisdom is still to use a tube preamp with the solid state (in this case, GaNFET class D) amp. Our class D is designed to be easy to drive with any kind of pre... | |
| Balanced XLR vs RCA for phono stage There are advantages to the AES48 standard, but I don't think it's accurate to say that only amplifiers meeting the standard are "truly balanced." By way of example, most (if not all) ARC amplifiers are differentially balanced yet don't comply w... | |
| Digital input amp @jeffrey125 Thanks for the correction- I knew that once upon a time... | |

| Balanced XLR vs RCA for phono stage XLR from my SACD player sends a slight increase in volume compared to it’s RCA output. Is it the cable, or is it the player’s output? In any case, use of XLR from that unit is yielding a slight volume increase. @macg19 When you see an increase ... |
