| High Current vs high power The Rowland 8Ti is a good example of what I was talking about.Into 4 ohms it is rated 400 watts, but the current figure states(from the website): 50 amps continuous, 100 amps peakIts pretty obvious this has nothing to do with power! 50 amps contin... | |
| Preamp Noise with High-Efficiency Speakers My comments on voodoo are just that some believe that an active preamp can actually add real musical information that the source isn't providing, this shatters me that some can believe this.You won't get any argument out of me on this! I am of the... | |
| High Current vs high power ^^ Yes, audiophiles have seen those pesky spec sheets for amplifiers for decades, but so little on them tells us what is going to sound right that you still have to do the audition. More fodder for the objectivist/subjectivist debate... | |
| Tube vs. SS Dilemma After looking at the Stereophile review, I suspect that this speaker is better being on the four ohm tap than the 8 ohm tap of many tube amps. Musicgeorge11, it is also obvious that you had some bad tubes in your equipment- refer to your comment a... | |

| impedance question and tubes Since speakers often do not have linear impedance curves, you do often have to try other impedance taps to see which offers the best performance.'Light loading' can be good for the power tubes but can also introduce more harmonic distortion, which... | |
| High Current vs high power This is a commonly misunderstood concept in amplifiers. What is meant by 'high current'?Does it mean that the amplifier behaves as a voltage source, and so can double power as the speaker load is cut in half or does it mean something else?It means... | |
| Preamp Noise with High-Efficiency Speakers George's Lightspeed is IMO one of the best PVCs made, but- If then you don't like this, by all means colour it to your liking with a active preamp of your choice, this is why ALL active preamps sound different as they are not a strait wire with ga... | |
| Tube vs. SS Dilemma Musicgeorge11, it may be that your speakers were not particularly tube-friendly. If so you will not get your tube investment dollar out of the amps. You didn't mention your speakers in your post, so this is mere speculation. What kind are they? | |
| Has anyone tried a "leather" turntable mat? I once knew this guy that got raw pigskin from the local slaughterhouse. He would make platter pads from it- his idea was that hands held instruments- why shouldn't skin hold the LP too?His LPs got greasy, he had to keep the pad in a mayonnaise ja... | |
| Preamp Noise with High-Efficiency Speakers George, you can't count on a preamp having a 47K input impedance- that is for phono, not a line section, which might often be more like 100k. Amplifiers frequently have 100K input impedances too. When you run impedances that high and then introduc... | |
| Tubes vs Solid State Zombie thread come back to eat your brains!You don't have to know anything about the technology of tubes and transistors, or even the sound of them to know that something special is up with tubes. Tubes were declared obsolete about 55 years ago- t... | |
| Preamp Noise with High-Efficiency Speakers If after that you still prefer an active preamp, then it's the colouration/distortion of it you like, which is a bandaid fix for something else that's wrong.Its not a bandaid- an active line section can control an interconnect cable and reduce its... | |
| Preamp Noise with High-Efficiency Speakers The problem with a passive is that it can act to functionally reduce the value of the coupling cap that might be in the source, such as a DAC. In doing so this is how bass impact can be lost. The other problem is that the system will be a lot more... | |
| Do we still need 6550 or KT88 tubes? I've heard from service technicians that the KT-120 are just terrible (that seems to come from a reliability viewpoint). 6550s and KT-88s will have a home for decades to come in guitar amps and vintage audio gear. So yes, we still need them. |
