| Is my preamp useless? ^^ The quick answer is here:http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1426779273&openflup&16&4#16 (earlier in this thread).The longer answer is that mathematically, no passive control is going to work perfectly as intended if i... | |
| Best Preamp = No Preamp? When Mercury Records recorded at Northrup Auditorium in Minneapolis, to do so they parked their recording truck behind the building and ran about 200 feet of cable from the mics to the recorders mounted in the truck.You can read about their truck ... | |
| Describe ube sound vs solid state Unsound, just because an amplifier cannot double its power as impedance is cut in half is not the same thing as saying that the amp cannot do flat bandwidth on a given loudspeaker. There is more to it than that! | |
| Tube Amp - Output Power Fuse Protection You need to know plate voltage and how the tube is biased to determine dissipation and how hard the tube is run. They won't tell you. So simply look at the watts per channel, and divide it by the number of tubes. 80 watts per channel out of two KT... | |
| Electrostatic speakers and low volume resolution Well, you may not have enough power at higher volume levels... | |
| Electrostatic speakers and low volume resolution Broadstone, from the sound of it all you have to do to confirm or deny my theory is to hook up your integrated amp. With less power, you will be pushing it harder and likely not using it in the lower power region. Try it and see if your low level ... | |
| Best Preamp = No Preamp? George, did you know our preamp can drive 32 ohm headphones directly? My speakers at home are 16 ohms and it can drive them too. Yet it is a tube preamp. The line stage is a miniature power amplifier. It has a low output impedance that is the same... | |

| Is my preamp useless? A preamp does these things:1) provide volume control2) provide any needed gain3) provide switching for various sources4) control artifact from interconnect cables.Of these the last is the least understood. Since you don't need any gain my recommen... | |
| soft thump and driver moves...even with no signal Ha! Called it. Its not likely that its a bad connection on the tube socket- that would sound different. Your handling of the preamp tubes has likely stopped the errant tube for a while, but my forecast is that it will be back eventually.You swappe... | |
| Best Preamp = No Preamp? Most SS sources (excluding tube ones) have an output stages that can equal and sometimes better many preamp output stages, especially tube ones.So the myth that a preamp can drive the interconnects to the amp better is a "furphy", and started by p... | |
| soft thump and driver moves...even with no signal If this occurs fairly often, first thing to do is swap the interconnects from the preamp left for right and see if the problem moves to the other channel. If so, the problem is in the preamp. If not- its likely one of the driver tubes. | |
| Electrostatic speakers and low volume resolution Broadstone, that is true to a certain extent but should not be held as gospel! Generally speaking though, Martin Logan speakers are tricky for any tube amp due to the low impedances of less than 1 ohm at high frequencies. Quite often though they c... | |
