| Who makes That there's a "black box" aspect of synergy or a witch's brew of "X" factors going on in an amp that come together (or not) when driving a particular speaker.To this point, I seem to recall that a while back Al may have posted something in anothe... | |
| Who makes Hi Al, the significance isn't. IOW, yes, to your first question. As to the second, no, simply because, well, the term is IMO mis-used. To be clear here what I am saying is that the actual impedance of the circuit is not changed. IOW what is reason... | |
| tube amps and electrostatics ^^ yes. But then you are dealing with 20 ohms or more in the bass. A 600-watt transistor amp just became a 250-watt amp.This is why tubes work so well- the higher impedances are not as challenging. In the case of the Sound Labs, this means a 150-w... | |
| Who makes Al has it right of course. If I can add something, those high Joule numbers mean that it will be harder for the output stage to modulate that power supply. This reduces IM distortion at higher output powers. Nice huh?Bombaywalla, I think you have ... | |
| tube amps and electrostatics Bruce, I would not loose heart!The issue that makes ESLs hard to sort out is that their impedance curve is related to a capacitor rather than drivers in a box.But the allure is of course that ESLs are very fast and revealing, and if set up right, ... | |
| Who makes Mapman, I agree with your comments buy you might be missing something: how the use of negative feedback affects this.As you probably know, most transistor amps (especially ones that can double power nicely even to 2 ohms) employ negative feedback.... | |
| tube amps and electrostatics Ralph and Al, the discussion begs the question of how can one know whether an ESL was voiced to be driven by a tube versus SS amp. Obviously Sound Lab ESLs were designed to be tube friendly, ergo Ralph's comment that his amps have been coupled wit... | |
| tube amps and electrostatics Here is what is real... the feedback used in transistor amps is what keeps them from destroying the speakers. That same feedback is also one of the things that makes a transistor amp bright. It can do that to tube amps too, but tubes can run with ... | |
| tube amps and electrostatics Al, as most here already know, is one of the more knowledgeable contributors on this website. I feel really fortunate that we often agree :) Al did indeed get it right, as usual. The problem you often run into when trying to use solid state with E... | |
| Who makes Cdc, FWIW, the example you cited of the Zamp cannot be correct at least not into any known speaker load.The power formula is P= Voltage X CurrentWhen related to Ohm's Law the power formula can all be shown be P=Current squared x ResistanceThe lowe... | |
| tube amps and electrostatics And what you would have also heard was a more defined and extended treble because those quads and these (ML's Acustats and other els's) go below 1ohm in the treble and start that impedance dip at 10khz.Tubes I aggree with these speakers still soun... | |
| Who makes ^^ Cdc, its actually simple math. All speakers are driven by power and if the amp can make the power into the speaker the voltage and current will be exactly the same regardless of the amplifier.Obviously there is more to it than that- what is goi... | |
| tube amps and electrostatics Regardless, the ability of an amp to double power as impedance is cut in half is not an advantage on an ESL. This is because the speaker really wants to see constant power regardless of its impedance at a particular frequency, as the impedance cur... | |
| Who makes The way to get a conventional solid state amplifier to operate in the Power Paradigm would be to add some current feedback, but not so much that it acts like a 'current source' device. To my knowledge, no such products exist - for now. If you want... | |
| just an observation for comment The LP collector rule of thumb is to seek the original LP from the first stampers from the country of the recording's origin. Its rare that any reissue will sound better. This is because there is a feedback loop between the record label and the ar... |
