| Why will no other turntable beat the EMT 927? Raul, I'm calling bogus on your last post. You idea of EQ is skewed. Once played back, LP has less phase shift than digital, owing to its superior bandwidth. Phase shift introduced in record is canceled out in playback. In terms of distortion digi... | |
| Why will no other turntable beat the EMT 927? there can be no comparison IMHO either in design or practice between the precision, significance, magnitude or commonality in practice of the errors common or possible with the half century old 33 1/3 vinyl system compared to modern digital.Analog... | |
| Pre-amps with seperate power supplies ..... I bought my Cardas power cords at CES in 1990, about 5 years after we switched to IEC connections. By that time Cardas was already doing quite well for himself :)I do remember thinking that I didn't want to deal with how people would cut up the wi... | |
| HELP-woofer moves alot when playing lps A rolloff point at 18Hz will cause phase shift up to 180Hz- IOW, 10X the cutoff frequency. The phase shift will manifest as a loss of impact, increasing as frequency is decreased. This might not be all that noticeable if the speaker has an LF cuto... | |
| Preamp for headphone use The Atma-Sphere MP-1 line stage can drive headphones like that directly from its main outputs. | |
| What's with 4 ohm speakers? Jjrenman, you are absolutely correct. People commonly assume that Efficiency and Sensitivity are the same but that is only true into exactly 8 ohms. | |
| Pre-amps with seperate power supplies ..... Seems to me Fulton was making power cables. Its been a long time but I seem to recall Sumiko had something too. | |
| When an amp puts out 90 watts.... Bifwynne, Our amps don't use any feedback at all, yet they can work quite well with speakers that have some pretty wide impedance variation. It all has to do with the intention of the designer of the speaker. ZOBEL networks are one way you can get... | |
| Pre-amps with seperate power supplies ..... Atmasphere, Years ago before you made your first preamp aftermarket power cords were not popular. I first became aware of after-market power cords in about 1985. Not sure how long they have actually been around, but at least since then... that is ... | |
| Do 45 RPM records need higher anti-skate setting? 45s are NOT cut with greater modulation (if they were the sound would be louder through the speakers), the goal of the mastering guys is same volume, so the idea that different anti-skate is required is far fetched. Same anti-skate.I have quite a ... | |
| 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... |
