| Are Pre-Amps necessary? IME this always comes down to cables. I used to know this guy named Robert Fulton who, more than anyone else in the world, founded the high end audio cable industry. He had his special RCA cable that sounded better than the average Radio Shack cab... | |
| Single driver vs traditional 3 way loudspeakers Well I may have ead something in the descript about the odd spiked phase plug as helping eleiminate some beaming effect.It doesn't. It allows you to hear highs that you would not otherwise.That is why any 'full range' driver is nicely supplemented... | |
| Why so many tubes? Paralleling tubes or going push pull can increase power but also can muddy the sound. The word 'can' in the statement above prevents it from being false. Going PP can also **decrease** muddiness by decreasing distortion. The trick is to not combin... | |
| Class A into Class AB @itsjustme FWIW, 0.5 Ohms is a good assumption for an emitter resistor in an output section. 1 Ohm is not! | |
| Single driver vs traditional 3 way loudspeakers has that spiked center phase pulg which eliminates beaming.This conclusion is false. What the phase plug does is prevent cancellation from one side of the cone to the other, so the highs generated can actually be heard. It does not prevent beaming... | |
| Hagerman Audio Labs Humbucker This is to solve a very specific problem- hum when Grado and Rega are used together.Years ago I found a simpler method. The motor is ungrounded. So I ran a wire connected between the motor case and the tonearm ground. No more hum with the Grado ca... | |
| Looking for new speakers for large audio room Most of the speakers brands most of you recommended aren’t being sold by any local dealers in Thailand Due to the size of your room unless you have a very high powered amp horns of some sort are probably in the mix. So do you plan to only work wit... | |
| Why so many tubes? Yeah but Ralph you are Da Man with stuff like this so I have to ask, what about going the other way? Why not use one great big high power tube? The reason I ask is some guys I respect are going that way with SET and real happy with it. Of cours... | |
| Amperex 6DJ8 tube construction I can add a bit to that. The getter is used to trap all remaining air molecules in the aluminum of the getter. After all the air is pumped out and the glass sealed, the getter is fired with a very high voltage. The air is thus trapped in an alumin... | |
| Why so many tubes? There's a 50cc class of racing motorbikes. Back in the 50s and 60s it became all about how many cylinders you could get to displace only 50cc. Things got real small and because things really didn't weigh all that much revs were over 20,000! So the... | |
| Looking for new speakers for large audio room @shawarma Classic Audio Loudspeakers makes two speakers you might want to look at. The first is the T1 and the second the T3. They are 98dB so will be able to fill your room with a moderate amount of power (I suggest about 100 watts minimum). The... | |
| Why so many tubes? Seems like a complicated way to reproduce music. And yes a little bit of laziness involved, but electrical engineers make lousy writers as the subject is a difficult exposition. So some of tubes are the same as the power transformers? And I am o... | |
| Then there were 2 arc uses printed circuit boardsit is neither a positive nor a negative+1 | |
| How important is the pre-amp? That was the standard and had the very significant advantage of simplicity of the signal path. More recent marketing efforts promote balanced connectivity. Balanced topology imposes twice the circuitry into the signal path. Abandoning single-e... | |
| Then there were 2 ARC is point to point vs Rogue circuit board?Huh? That's news- I've never heard of a hand-wired ARC product. All that I've ever seen have employed circuit boards. |
