| 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... | |
| 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.... |
