| Amp fan cooling without dc current in the 110 line I'm real skeptical that a normal PC case fan can inject noise into a line. More likely it's the switching power supply making noise. | |
| Is it the beer or do speakers/electronics really need some extended warm-up period? I usually let my amp warm up for an hour or two before listening. I throw on just something for the first 15 or 20 minutes before sitting down to really listen and that seems to make a difference. I don't know if the speakers or amp, but there's a... | |
| Are medium power push pull tube amplifiers more articulate than high powered units? I'm a real happy camper with my simple push-pull F5. I've got it making about 40wpc and that's plenty. I've become a big fan of simple. I'm not so sure about tubes. Never played with them. I've been thinking about a tube pre-amp which seem to me t... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? I'm thinking it's easier to tailor an amp to a pair of speakers. I'm not religiously opposed to loop feedback. As with many things, it's in how it's applied. Speakers like Focals are most definitely designed for a voltage source. That rules out a ... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? The problem I've got with the concept of "perfect" or "zero distortion" amps is that it really doesn't matter. How perfect is that amp with a loudspeaker drawing current all out of phase, pumping power back into the amp, and presenting impedances ... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? @roger_paul The harmonics arise from unavoidable variations in gain. All gain devices have capacitance, inductance, and resistance. There simply isn't such a thing as a perfectly linear gain device. The only way to make a device behave in a more l... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? Circuits vary the pitch through intermodulation distortion through summing the fundamental with harmonics. That has nothing to do with the speed of electromagnetic waves passing through circuits at damn near the speed of light. It’s the compound a... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? I'm sorry. I'm just not buying this. I'm sitting here listening to an amp that's flat -.0dB DC to -.25dB@500kHz and will produce text book perfect square waves to 200kHz. And it does it in P-P class A. I'm no engineer, but I'm pretty sure there ar... | |
| Why are tweeters so high off of the ground in many tower speakers... The tweeters on my Focal 936's are something like 39 inches high. I barely notice and difference if I try to sit tall and ear level with them, but standing makes a noticable difference. I can't believe I'm going to say this, but I'm actually going... | |
| Ugly vs Gogeous speakers I agree with Shadorne. The Vivid speakers do have a certain organic soft fecal character to their shape. | |
| Ugly vs Gogeous speakers I really like the shape and colors the Focal Sopra No.2 comes in. On the other hand, I think JBL has made some of the most hideous speakers in history. I feel like whoever styles those things has some strange obsession with butts and anuses becaus... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? I got the point. I think he makes his point very clearly. | |
| Directionality of wire I think we're all laughing at you. | |
| Are future improvements in Amp/PreAmps slowing to a crawl? @roger_paul I appreciate the offer, but at the moment I'm involved in a serious legal situation involving my daughter and I need to apply all of my available resources to that effort. | |
| Are future improvements in Amp/PreAmps slowing to a crawl? @roger_paul Sorry. Your prices are way out of my league. I can build some very nice pre-amps and mono-blocks for price you want for a pre-amp. My F5 cost less that $1000 to build and it's a very nice amp. |
