| Is my preamp useless? ^^ This post is incorrect, as the problem is not the control but the interconnect it drives, and of course the drive actually comes from the source- I explained this in my prior post.Why is it then, when you put different active preamps in a syste... | |
| Describe ube sound vs solid state Actually global negative feedback cannot to that in an amp. What it can do is force the amp to put out *half* has much power into an impedance twice as high- and therefore satisfy the voltage drive model of 'typical speakers'. So add enough feedba... | |
| Electrostatic speakers and low volume resolution You are quite welcome. Should I point out that tubes have a reputation of doing low level detail better than transistors? The more resolution you have (and ESLs have a lot) the easier it is to hear this.However since you have Martin Logans, in ord... | |
| Describe ube sound vs solid state ^ I got that and meant the same thing. "Typical speakers".Just because an amplifier does not double power into half the impedance does not mean it cannot drive such a speaker perfectly well, without frequency response variation. Doubling power is ... | |
| 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... | |
| Describe ube sound vs solid state Geoff, you may have missed Atmasphere's second from last post. I just wish he would name names.Ridley Audio. http://www.ridleyaudio.com/Technology.htm | |
| 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... |
