| tube amps and electrostatics Impedance can be measured with a potentiometer of about 50 ohms or so, a signal generator and a DVM. It takes some time, as with this technique you have to put points on a graph.You put the pot in series with the speaker and drive the combo with t... | |
| The future of preamps Audiolabyrinth, Krell states that the gain of their amps is only about 25db. FWIW that is quite unusual (I had assumed their gain to be a more typical 30db), so in a high power amplifier you would indeed need more than 4 volts to full output. The ... | |
| tube amps and electrostatics The B&W 802D is, FWIW, an excellent example of Voltage Paradigm technology. The woofers are each 8 ohms, but also 3db less efficient than the 8 ohm mid range and tweeter. They are in parallel, which requires the amplifier to double its power i... | |
| The future of preamps Wadia is still very much around. Owned by the same company that owns ARC. They are a good example of why an analog preamp is handy- their volume control is an example of what I was talking about earlier.Audiolabyrinth, I can tell you with great co... | |

| The future of preamps The loss of transparency introduced by the preamp needs to be counterbalanced by other sonic benefits.Actually if the preamp is working right, most people experience an increase in transparency, not a loss. I have already mentioned one reason why;... | |
| To Tube or not to Tube...... Mikewerner, one argument for tubes you may not have considered: semiconductors are going obsolete all the time. Just try finding output devices for a MOSFET amp made in the 1980s and you will see what I mean.In the tube world we don't have this pr... | |
| tube amps and electrostatics Bifwynne, another speaker you might look at is Audiokinesis. His speakers are not only more efficient, they are also very easy loads (some of them are 16 ohms) without crazy phase angles, yet also quite musical and good bass extension.I think you ... | |
| The future of preamps Hi Al, take a look at this link on DIYaudio:http://www.diyaudio.com/forums/solid-state/161371-krell-current-audio-signal-transmission-c-s-t-current-mode-technology-cmt.htmlScroll down a little and you will see something very similar. I rather doub... | |
| Are Rodgers ls3/5a as good as advertise? & Why Fun little speaker! Tube amps only- its 16 ohms. 35 watts is all they handle. But that is all they need too, as you are only supposed to be a few feet from them. Limited bandwidth obviously, but what they do they do well. | |
| tube amps and electrostatics Bifwynne, speakers get a reputation for being 'hard to drive' for a reason. What you might want to think about is the impact on the amp. It does not matter tube or transistor, if the amp is driving a hard to drive load the result will be more dist... | |
| The future of preamps A preamp has four functions:1) control gain2) provide any needed gain3) provide input switching4) control the interconnect cableOf these functions, most digital sources provide one, which is to control gain. Unfortunately, Redbook specs call for t... | |
| Quad ESL 57 system upgrade help requested Stacked Quad ESL57s don't take a lot of power so you don't need a big amp. We've had a good number of people use our M-60 in that sort of installation with good results. Without question though with ESL57s you are looking for a good tube amplifier. | |

| 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... |
