| 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 ... | |
| Working with 78’s @europeansoundtrack , @mke246 is giving very good advice. No 78 I know of uses RIAA EQ. In the late 1950s a number of preamps had several of the more common 78EQ curves built in. One of my favorites was the Harmon Kardon Citation 1. It also had sw... | |
| Digital input amp "Doubles the power when reducing impedance" So what. Any good amp can. "Switching, but not class D". OK, they did not say what it is though. "Exactly like class A" Nope. Not at all. "More efficient" Yea, so is class A/B, G, H and D. ... | |
| 300b lovers And the colorations from different part selections are not the same as SET. This makes sense when you reflect on it ... the balanced circuit is cancelling most, but not all, colorations, and the residue left over can be unwelcome and surprising. ... | |
| Best Full-Function Preamplifier If you want the best, isn’t it better to go with a line stage and outboard phono preamplifier? @vonhelmholtz , @lewm beat me to the punch but the simple answer is 'no'. When the phono section is built in the designer has better control of the ... | |
| ? about Smoking Power Amp @mfiddles A dummy load is usually a high power resistor that won't fail when subjected to amplifier power. That way you can run an amplifier without having to listen to it. If run with no load you won't learn if the amp will hold up. Usually you'... | |
| ? about Smoking Power Amp @mfiddles D753 is a diode in series with the 10 Ohm resistor, R783. The screen for the resistor might be visible once you clean the board. This resistor is in the protection circuit and is not part of the amplifier circuit itself. So the amplifi... |
