| Sonic atributes ultralinear vs tetrode vs pentode Trelja, choosing the midpoint on a scale may be simple math, but it's not simple dimensional analysis. Since wpc is a ratio scale with a meaningful zero, the proportions that Ralph referred to apply in this case. If this is confusing to you, you m... | |
| Sonic atributes ultralinear vs tetrode vs pentode "What first needs to be recognized is that 0 is not one of the endpoints for a comparison between triode (20 wpc for the example at hand) and pentode (60 wpc). UL (40 wpc) is exactly midway (IOW, 50% not 66.67%) between the two. As such, the word ... | |
| Steve Jobs we will miss you "Pete Seeger doing "Sweet Low Sweet Chariot" It's interesting that Seeger would sing for a capitalist such as Job. Seeger an admitted committed communist singing about the one thing he hates more than meat eaters and that's individuality."Wow. I'm... | |
| Your First System Wind-up WW II olive drab suitcase 78 player. Built a Dynaco SCA-35 in 1964, to go with new AR speakers, and a turntable cobbled together from a Motorola mono system of my parent's. Not loud, but quite a bit better than the 78. Wish I still had all... | |
| The downward spiral..... Well, if you really want a downward spiral, I'm listening almost exclusively to a cheap mini watt tube amp, while at least 12k worth of pre and power amps languish in the closet. It's disgusting, but I really prefer the cheapest tube amp around to... | |
| So, what DON'T you spend money on? No fancy amp yet--sticking with McIntosh 6900 integrated and miniwatt tube. Cheap speakers. Haven't bought any music in years. Over 12000 tunes on ipod ripped from CD and vinyl collection. Spend most on awesome guitars. | |
| How can a 40 watt amp outshine a 140 watt amp Thanks Bryon. An intellectually honest way of setting up the experiment would have been to test whether a listener ever gets it right more often than chance. A totally different analysis, and a money losing proposition for him, I suspect. | |
| How can a 40 watt amp outshine a 140 watt amp How can a 40 watt amp outshine a 140 watt ampSo, I've resisted responding here for quite a while, but temptation has overcome me. My first thought is that the challenge is pretty silly, in that it relies on crippling the better amp, or jacking aro... | |
| Why no heated gear? "The entire tube, inside and out, will eventually reach the same temp whether heated from within or from outside."From that unimpeachable source, Wikipedia:"Vacuum tubes require a large temperature difference between the hot cathode and the cold a... | |
| Why no heated gear? I don't know about your garage, but mine won't heat up to the operating temp of an internal combustion engine. | |
| Reliability of Cary Audio Products "This is useless data. The only valid data is generally collected by the manufacturers themselves or through some larger, high volume dealers."Data generally speak for themselves. The sample may be problematic, but unless the respondents are lying... | |
