Turntable Pre-Echo Sound....?
And of course that distortion is inaudible, contrary to the far lower distortion introduced by, say, a digital facsimile of the same recording, which everybody can hear!Bob P. 
Is analog & vinyl anoying? Is it worht it.
I think that the carrier signal was at 44K Hz, but certainly above 40K. That of course forced cartridges to track at much higher than previously.The response, however, wasn't necessarily flat to 44K and many carttridges achieved the higher frquenc... 
low vs high gain
Chris, only if your preamp is incapable of driving the amp to full output at the lower gain will dynamics be affected by the lower gain in the power amp. For example, if the gain at 32db settings means that .5 volts at the preamp output will drive... 
low vs high gain
Generally, with variable gain on power amps, one sets the gain as low as possible for the max volume level one wishes without demanding more than whatis posible from the preamp. This gives the best SN at the speakers.In your case, use the 26db if ... 
Cable Costs Relative to System
Joeyboynj, pray tell us how you specify your PCs if you don't know how or why they change the sound. 
HiFI Fuses ?
Benie, I always thought that looking for explanations on how or why things work was called curiousity or having an open mind. Simply stating that one doesn't care about 'why one hears a difference' or stating that why or how something works isn't ... 
HiFI Fuses ?
TBG, I need more than apocrophal evidence that direction matters, since I don't even detect any difference in even 'ordinary' fuses let alone 'directional' ones.By the way, what is directional about these fuses, besides the arrow (I presume) marke... 
HiFI Fuses ?
Which misinformation? So AC current does not change direction? Ground and neutral are not necessarily the same. Even if the 'directional' fuse were a partial diode, it would act as such in either direction installed since the current reverses as m... 
HiFI Fuses ?
Ah yes the directionality feature, which might make sense IF the current always flowed in the same direction. Unfortunately AC current changes direction 60 times a second and makes the direction that a so-called 'direction oriented' fuse a moot po... 
Break in period
Yes, Shadorne, I have always wondered how people can hear the difference between 0.002% THD on SS amps and 3% 'natural' harmonic distortion on tube amps over speakers with some 5-10% THD and sometimes up to 100% when the speaker 'doubles'! Methink... 
Nakamichi Power amps
Don't know about those, but I have a Nak 620 (circa 1977) and it sounds great and provides about 100w/ch into 8 ohms and 150w into 4 ohms. Interestingly enough, this amp operates in 'pure' class B with low feedback. With feedback removed, the Harm... 
Tubes and forced air cooling ...
When you are 'drawing' the heat away from the tubes using induced draft, what air do you think that the tubes air are getting to remove the heat? The same cold air as if you had the air 'blowing' directly on the tubes as in forced draft. It doesn'... 
Cooling fans for tube amp
Again, induced or forced draft doesn't change the amount of air cooling the tubes nor its quality. Even if the pressure is positive inside the cabinet, dust enters from the room in the air being blown in by the fan, unless one has a filter on the ... 
Cooling fans for tube amp
Forced draft or induced draft, it doesn't matter, the tubes don't know whether the air is being 'pushed' at them or 'pulled' by them. Usually, however, one can get more air flow for the same size fan in a forced air setup, but the difference isn't... 
Are DIY Cables Worth It?
Since speakers run on AC through the wires, how does one determine which is the 'return' run of the cables on which to use the double run? And how can that make a difference since the current direction changes up to 20000times a second?
