| Balanced or Not Al, I think I know a better way than that, but it requires a mod to the amplifier. But it is a very simple mod!Any amplifying device (tube or transistor) has two inputs. On a tube this would be the grid or the cathode. Taking that a step further, ... | |
| Best Electrostatic loudspeaker? Best Electrostatic ?!?!Yes. The very best. Made by Sound Lab. Why is it the best? Its the one that plays the deepest bass and has the greatest dynamic range. That is why- otherwise, Quads, ML, etc. are all quite convincing (and excellent IMO) due ... | |
| Solid State for Rock and Tubes for Jazz, Yes or No Mapman, I don't know how many times I have dropped this link but here it is:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpIn short, damping factor has little to do with getting bass, in fact if you have too much that is wor... | |
| Passive Pre-amp: Improves overall sound quality?? Lets list what a preamp does:1. source selection2. voltage gain3. attenuation4. buffering (impedance matching)5. tone control (older preamps,typically)Let's get rid of #5 for now- passives don't have them, most good line stages don't either.To tha... | |
| Dielectric grease and tubes There should be no arcing on any tube socket if it is in good condition and no grease is needed. Some sockets can be damaged by arcing caused by a failure of the tube, if this happens the grease will not protect anything. | |
| How to get the impact of a live concert? Wolf, the SPL meter would probably work fine, just place it near the speaker so you don't have to run huge volumes. If you are really intent in this borrowing a sine/square generator should not be that tricky.BTW, a sine generator does not do this... | |
| Recommendations for Speakers that sound like Snell No-one has mentioned the B yet, which was also an impressive speaker. With 22 Hz response, it could shake the walls, and with its obliquely aimed rear-firing tweeter it imaged quite well. It was easier to drive than the AIII was, I thought it soun... | |
| Passive Pre-amp: Improves overall sound quality?? Yes a lot has been written about the passive/active debate.In a nutshell, the math (on which all electronics is based) goes against you when you run a passive system. The Lightspeed is no exception. You can improve the situation slightly by using ... | |
| Solid State for Rock and Tubes for Jazz, Yes or No If the tube amp is happy with the load, IME you won't find a transistor amp with more slam. You don't need a super low output impedance to control 15" woofers either! Its all about how the amp interfaces with the load.more:http://www.atma-sphere.c... | |
| Capacitor question Charles1dad, in an SET The power supply is a lot more critical than it is in a fully differential amplifier! IOW an all-film power supply in such an amplifier will not have nearly the effect that it has in an SET. | |
| How to get the impact of a live concert? Hi Wolf, sure:You need an amplifier of any type, a speaker, a VU meter and a sine/squarewave generator.Run the sine through the amp and speaker. Put the VU meter on the amp/speaker terminals and set the level for 0VU.Now cover up the meter, turn t... | |
| Soundlab Speakers - Budget Amp Suggestions Grannyring, from what I understand that shunt resistor is a problem for any amplifier, even transistors. There is a reason it is rated for so many watts- amplifier power is used to heat it up. It does not matter what kind of amp you have.If you re... | |
| How to get the impact of a live concert? Wolf, General Electric proved that that the human ears uses odd ordered harmonics to determine the volume of a sound back in the mid-60s. Its not really open to debate anymore- its more about- what to do about it?IMO what their research indicates ... | |
| Coherent Speakers. 'Clear'? No mention of amps... this *does* sound like an ad. | |
| Soundlab Speakers - Budget Amp Suggestions Grannyring, what mod did you perform? Did you remove the big resistor? |
