| Current amp vs Voltage amp Hi Unsound,Yes, "such a ss amplifier would almost always be able to provide more linear output regardless of whether they are ESL's or dynamic speakers, and that would hold true whether or not the impedance swings were wide or not." (Assuming that... | |
| Current amp vs Voltage amp 05-05-13: UnsoundAl, the wouldn't sensitivity of the speaker vary along with the impedance? Sensitivity, defined as the sound pressure level (SPL) generated by the speaker at a given distance, in response to a given voltage at its input terminals,... | |
| Current amp vs Voltage amp Hi Unsound,I suspect it to be true that more often than not speakers having widely varying impedances will provide flatter frequency responses when driven by solid state amps. But if so, that would simply be because more often than not speakers ar... | |
| Current amp vs Voltage amp A note on terminology: Unless there are some extremely unusual exceptions out there, all audio power amplifiers amplify both voltage and current, so the terminology in the subject line of the thread is a bit misleading.Solid state amplifiers havin... | |
| Current amp vs Voltage amp Hi Bruce (Bifwynne),I've looked at the references you provided, and read your post, and I think that everything you've said is essentially correct.Basically, your VS-115 has a lower output impedance than many or most other tube amps, on a given ta... | |
| Is soundstage just a distortion? 05-03-13: GeoffkaitIt's a little ironic that there are such things as records and CDs that test for soundstage since the soundstage you get is going to be limited by the, uh, limitations of the system you play them on. Kinda like seeing an ad for ... | |
| Current amp vs Voltage amp I think that you'll find this thread and this one to be informative.Also, if you haven't already, see Atmasphere's paper on Paradigms in Amplifier Design.Regards,-- Al | |
| Is soundstage just a distortion? Hi Mapman,Are you able to rule the room acoustics in your tests as a factor?I would think that listening from 2 feet away, directly in front of the tweeters, pretty much rules out room acoustics as being responsible for the effect I described.Mayb... | |
| Is soundstage just a distortion? Thanks, Newbee. To clarify, though, what I was saying is that my experiences listening to the warble tones on the test record I referred to led me to believe that it is the nature of our hearing mechanisms themselves, completely independent of ref... | |
| Is soundstage just a distortion? Regarding the question about soundstage height, while I can't say this with 100% certainty, experiences I've had listening to a test record containing half-octave warble tones have led me to believe that our hearing mechanisms perceive certain par... | |
| Turntable Swamp. . .what to buy? Another vote for SOTA.I think you will find this article to be well worth reading.I have an early SOTA Sapphire, which is approaching its 30th birthday. It works as well as when it was new, without ever having required servicing. I have never felt... | |
| Cable Length Query Sounds like an excellent plan, Marcus. The Sim Audio preamps appear to all have low output impedances (e.g., 50 or 100 ohms). You will be using balanced interconnects. The impedance of the Ethos speakers descends to very low values at high frequen... | |
| Cable Length Query Emerson, yes the JW Audio Cryo Nova is described as AWG 12, consisting of two solid core conductors twisted together. A 15 foot length of that cable is reasonable in terms of resistance and inductance, relative to the impedance characteristics of ... | |
| Monitor close to the wall to replace Allison 4s Ok, I see what you are saying, Denis. I hadn't understood the reference to 4 runs of single cable. So you are biwiring to each speaker from the outputs of each of the two channels of the amplifier that is dedicated to that speaker. As you say, tha... | |
| Monitor close to the wall to replace Allison 4s Denis, if there are any connections between the high frequency and low frequency binding posts on the back of the speaker they should be removed. Speakers having separate pairs of binding posts for the high and low frequency sections of the speake... |
