Chime in.What's the Best Cassette Recorder ever ? Zombie thread to eat your brains! | |
Tube Amps and Friendly Speakers - Back Impedance ^^ to clarify, its not about orientation.Sensitivity is 2.83 Volts at 1 meterEfficiency is 1 Watt at 1 meterIf the speaker is 8 ohms, they are the same.Now imagine a speaker with 90 db sensitivity.If the speaker is 4 ohms, the speaker will have an... | |
Tube Amps and Friendly Speakers - Back Impedance What you post is true, however: impedance affects sensitivity.Correct- but its important to understand that impedance has no effect on *efficiency* whatsoever. IOW, efficiency is the measure of *power* driving a speaker while sensitivity is the me... | |
Best Class A amp with SLAM The ability to weld and sound sweet are not necessarily mutual qualities!If the Krells were working for you how about find another set?? | |
Tube Amps and Friendly Speakers - Back Impedance ...most of the speakers on the 2013 Stereophile Class A list have some pretty wicked impedance and phase angle graphs, suggesting non-optimal tube amp matches.Stereophile does not recognize anything other than the Voltage Paradigm. So loudspeakers... | |
Let's share secrets of Lamm 6C33C tubes Jedinite24, and everyone else here:One way to reduce arcing on otherwise new tubes is to light up the filaments of the tube without applying B+ to it. Leave it in this state for at least 4 days and nights.This process is called preconditioning and... | |
VTA and SRA? ^^ No. Assuming the LP is flat, absolutely vertical is 90 degrees. Because the cutterhead that made the LP has to be angled slightly, the playback stylus is too. This is generally about 2 degrees, but must be considered an approximation, as it is ... | |
Tubes vs Solid State - Imaging, Soundstaging, 3D I suppose the standards that are applied do correlate to some extent with human hearing rules. It would be hard to see how products could be sold if not.What I am saying here in the last few posts is that for the most part, the measurement standar... | |
Tubes vs Solid State - Imaging, Soundstaging, 3D if I hear something that sounds good but does not measure well ( to some reasonable reference standard that it probably should) a little question mark will likely go off in my head asking "why".Now you know why, the technical specs don't jive with... | |
Tubes vs Solid State - Imaging, Soundstaging, 3D Few things are ever "universally" realized.Does not make sense to me that such things would be ignored by the experts whose products can benefit.Its all about the dollar. People often purchase audio gear with their eyes rather than their ears. The... | |
Calling all Horn lovers paired with amazing high-efficiency woofers of unknown origin that can actually keep up.Duke, as I understand it John (of Classic Audio Loudspeakers) builds those woofers himself, even winding the voice coils and field coils. | |
Tubes vs Solid State - Imaging, Soundstaging, 3D Assuming the noise floor is low and can't be heard anyhow, what is there to hear below it?Al's comments above are the correct answer to this. Chaos Theory points to the 'why' of it- the amplifier with feedback is operating in a chaotic fashion whe... | |
Tubes vs Solid State - Imaging, Soundstaging, 3D So hearing hiss is better than not hearing harmonics that can't be heard? I must be missing something?Correct- you are missing something. The hiss which is the noise floor of a zero feedback circuit is at a low level, just as the noise floor of an... | |
Tubes vs Solid State - Imaging, Soundstaging, 3D Al and Learsfool wanted to know more about the low level detail thing. Here it is.This has to do with the rules of human hearing/perception. Apparently we have the ability to hear into a noise floor and perceive detail which is interesting as norm... | |
Calling all Horn lovers Mapman, I've heard Duke's speakers in some pretty small rooms and they have worked great! I've also heard them in some larger rooms with excellent results. |
