| high power tube amps vs ss To that end I would like very much for either/both to cite some tube amps that are as fast as any ss amps they've heard so far. Imo, you can't get there without serious speed in an amp.One way to measure speed is rise time, the voltage you can rea... | |
| high power tube amps vs ss I do not consider Dynaudio speakers and tube amps to be a natural match by design in general, and would not do that without hearing first but that's not to say you might not find something to like there if you heard it. Agreed- in spades! | |
| What's with 4 ohm speakers? Those of us with a little technical knowledge accept and expect it because at lower frequencies dynamic loudspeaker driver output is proportional to voltage.The statement is ambiguous. We know that doubling power is 3db, and that there is or shoul... | |
| high power tube amps vs ss I'm a big fan of Nelson Pass, Ayre and Ridley Audio. That's my short list... I think there are a few other candidates out there but I've not been able to hear them. | |
| What's with 4 ohm speakers? Ngjockey, Pipedreams has done something like that. I've seen Pipedreams that were 4 ohms, and the exact same model in 16 ohms.Seems to me the ZU Definition, normally a 6 ohm speaker, is also available as a 30 ohm speaker. | |
| When an amp puts out 90 watts.... You might want to read more about this:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpAn amplifier does not have to double power to sound musical and to also have a lot of authority. | |
| Do 45 RPM records need higher anti-skate setting? Omsed, you seem to know something about this so perhaps you can explain some things. Doesn't the skating force vary from plus to minus depending on where the stylus is on the LP, assuming an optimally setup radial-tracking arm?Also, if the platter... | |
| What is a really good sounding low volume system?? Rrog, if you get their subwoofers, yes. We don't run their subs here, just the Bella Twins, as they have proven adequate on their own. FWIW I'm not a big fan of subwoofers- getting them to blend is a real challenge. One of the best I have seen is ... | |
| Current amp vs Voltage amp Mapman, thanks for your comments.I think there probably is some sort of point where the odd ordered distortion is not detectable. The problem is, we can hear that which is very difficult to measure! So how do we tell?? Test instruments don't seem ... | |
| Current amp vs Voltage amp Plus Ralph's paradigm (based around avoidance of use of NF as the best means to avoid those nasty odd order harmonics + the rest seems to stem from that), FBOFW, is more unique and "radical" and a huge minority relative to the norm these days, so ... | |
| Current amp vs Voltage amp I just do not buy into the assertion that power paradigm and no negative feedback is the only way to make music sound real.That's fine but it will not change the reality:The problem here is that the human ear is more sensitive to odd ordered harmo... | |
| Do 45 RPM records need higher anti-skate setting? Skating forces are a function of the rotation of the LP and the tracking error of the arm/cartridge. So if you increase the speed of the rotation, there will be more energy (skating force). | |
| What's with 4 ohm speakers? It's easier to design a speakers with a steady low impedance than a steady high impedance, something that some amps seem to have an easier time with. Historically there have been more speakers that can produce wave form fidelity with a lower imped... | |
| Current amp vs Voltage amp Historically speakers with lower impedances are more likely to be able to produce wave form fidelity than speakers with higher impedances.[facepalm]I can't let that one pass[/facepalm]. Its well known for decades that the Quad ESLs have had very l... | |
| What's with 4 ohm speakers? Some misinformation here:They're not hard to drive if you have a good amp. Also, 4 ohms is an average.4 ohms is not an average. Plus, you can see in the specs of all amps that its not a good thing. No matter what amp you have, the distortion will ... |
