| What do the different tube amp types mean? there are no practical OTLs using 300bs, 211s or KT88s; just for the record???Correct; for example at one of the links above, there is a 300b-based OTL. It uses 4 power tubes per channel and makes 6 watts per channel (for comparison an SET using o... | |
| What are the smallest speakers that are clean and flat down to 20hz? 3 dB at 20 Hz which is half as loud at 20 HzTo be audibly half as loud is usually considered 6-10db on account of the ear being on a logarithmic scale. I really mean the speaker does not roll off much or at at all at 20hz in a typical room. Ho... | |
| Tube Power Amp Suggestions @bigdish You say your speakers are 91 db; do you know the impedance? What speakers are they? | |
| Interconnects, some have directional indicators, why? we’re talking about metals that are 99.999999% pure in the case of copper. This is a common myth! No copper produced for audiophile or other uses is better than 99.99%. Anyone telling you anything else is lying. The fact is that while copper can b... | |
| Interconnects, some have directional indicators, why? @jea48 “There it was, right in front of me in black and white! The current does not flow around a loop setting up a magnetic field as I had, along with countless other engineers, been taught in high school and university. It is the other way ro... | |
| Interconnects, some have directional indicators, why? My post relates to the proposition that the electromagnetic wave that is the audio signal **in** copper wire or any conductor is comprised of photons, as are all electromagnetic waves. For a given value of 'in' I suppose increases or decreases t... | |
| What are the smallest speakers that are clean and flat down to 20hz? Headphones!Grado made a line source array that they showed at CES one year, just for fun. It made decent bass but it had a lot of drivers in it. Seems to me it was over 6 feet tall and they won't be manufacturing it. Otherwise you're simply going ... | |
| Interconnects, some have directional indicators, why? Photons. Hmm. Maybe that was the mail order NASA school...Actually, photons conducting in a wire is about as likely as you working at NASA which is to say neither happened. | |
| Interconnects, some have directional indicators, why? AC current is not flowing through the fuse. Energy is, in the form of an electromagnetic wave. That energy cannot exist without the current flow. You are correct in that electromagnetism is always there but it can’t exist without current! This lin... | |
| Solid State Amps for Quad ESL 57? with a much higher DF-that is, with a relatively high impedance, like many tube amps have. Damping factors of probably at least 20, which is probably 10 times higher than the Atmasphere S30. No wonder my friend’s friend got no bass from the S30... | |
| Interconnects, some have directional indicators, why? Sorry to report, atmasphere, the dude from Audioquest was actually referring to folks like you who insist that any directionality in the sound is due to the shield and who keep insisting there is not such thing as wire directionality whether it... | |
| Interconnects, some have directional indicators, why? Uh, I don’t think so. That was kind of the whole point of the Audioquest dude’s article on wire directionality. You know, the article you apparently mis-read. Besides, if a shield was connected at both ends of the cable you couldn’t really blam... | |
| New Mag-Lev Turntable But... when you dampen you can also lose extension. If you are really experiencing this then the damping is not working as you surmise. Its impossible to overdamp for vibration if the damping is indeed working correctly! | |
| Interconnects, some have directional indicators, why? @jetter Usually the shield is connected at both ends.<facepalm>Jea48 wrote,"The audio signal travels down the wire in the form of an electromagnetic wave from the source to the load."Bingo! All the young dudes carry the news, the young dudes... | |
| Interconnects, some have directional indicators, why? There is the widely accepted version of directionality: In most audio-grade shielded interconnects, as compared to standard coax, negative has its own internal conductor and the metal shield is attached to ground at only one end, thus defining ... |
