| Pre-amps with seperate power supplies ..... Years ago before we made our first preamp we began using IEC connections on our amps (which continued with our preamps) for the simple reason that audiophiles like to tinker.If the power cord is integrated into the equipment that means they might ... | |
| When an amp puts out 90 watts.... ZOBEL networks always have to be set up for a particular situation. Sometimes a choke needs to be in the network to prevent High Frequency rolloff. | |
| Do 45 RPM records need higher anti-skate setting? So the idea that a 45 rpm disc cut with greater modulation to also require slightly greater anti-skate sounds like its not that far-fetched. | |
| Do 45 RPM records need higher anti-skate setting? So far John's argument about variable friction does not seem to be addressed, or did I miss something?I've had conversations with several tone arm manufacturers; they seem to agree that there is no standard for anti-skate forces to be applied to a... | |
| What's with 4 ohm speakers? Or is there some type of industry standard and everyone measures these type of things the same way?They are supposed to, anyway. Of course the room is important, about 1/2 of the total system sound, IME.>The statement is ambiguous. We know that... | |
| Do 45 RPM records need higher anti-skate setting? Lewm, I think the part about centrifugal force to be a red herring. We don't need to discuss it further. | |
| When an amp puts out 90 watts.... I have seen some pnm impedance measures in stereophile that show wide impedance flucuations from 4 to 16 ohms at various frequencies. Far frm the constant high impedance that an amp like that would probably do best with. That depends on the amp. I... | |
| high power tube amps vs ss Since I have set up my system to be absent of loudness cues, it frees me to set the volume to the level that seems appropriate for what I am listening to. A solo guitar being quieter than a full orchestra for example. For example, do the harmonic ... | |
| high power tube amps vs ss The huge unflatness of the ear sensitivity chart would also seem to debunk any claims one might make about being able to hear flat frequency response. If you hear it as being flat, it in fact cannot be. Significant equalization would have to be ap... | |
| high power tube amps vs ss Regardless of design paradigm, isn't it the frequency response and distortion measured in the end that matter? These are components designed with certain criteria in mind that are obviously not interchangeable and must be matched together somehow.... | |
| high power tube amps vs ss But Ralph, I think you may have mentioned yourself that if a "pure" Power Paradigm tube amp that doesn't use negative feedback and that has a somewhat high output impedance is matched up with a speaker having a "bumpy" impedance curve, there could... | |
| 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. |
