| MM cartridges and capacitance Load and cable capacitance will interact with the inductance of the cartridge's coils to produce a resonant peak in frequency response, at upper treble or ultrasonic frequencies. Increased capacitance will raise the amplitude and lower the frequen... | |
| balanced connection, better than single ended? 10-03-10. Phd: The Audio Research amp that I purchased is a true balanced design. But more importantly I like the way it sounds. I used to own it two years ago and never took advantage of its balanced technology but was thinking that this time I s... | |
| solid state vs tubes 10-02-10: KoegzAtmasphere; I owned the ZERO gold ic and sp's. They were ok. I was never really thrilled with them. You spend that kind of $'s, even second hand, you should be ecstatic. I never noticed the improvement you speak of. I am not saying ... | |
| Modwright LS 36.5 or BAT VK-51SE I should add to my previous post that high output impedance that is primarily resistive, and is therefore high at high frequencies as well as low frequencies, can result in upper treble rolloff due to its interaction with cable capacitance. But th... | |
| Modwright LS 36.5 or BAT VK-51SE Since the output impedance spec of the Dude is not provided, it seems to be a situation where you'd have to hear the preamp in your system to decide if it matches or not. You'd want to be listening for rolled-off highs. I don't know what a resisto... | |
| One Super high end cable or mid level set? Pani & Mceljo,Keep in mind that with typical components at typical volume settings, signal amplitude (voltage) out of a cdp is not much different than the corresponding preamp output, and will often be higher in fact. Likewise for the amount o... | |
| SET Amp question Is there anything that will minimize the speaker SET interaction?In the case of speakers that are voiced to be used with high damping factor/low output impedance amps, such as typical solid state amps, I would expect that the tonal imbalance probl... | |
| Do power cords make an audible difference? Some background on this age-old philosophical question can be found here:http://en.wikipedia.org/wiki/If_a_tree_falls_in_a_forestGo ask the displaced squirrels whose former high rise is now little more than a duplex.Before Jim provided this charac... | |
| tube watts vs transistor watts? Magfan, as you've frequently and correctly pointed out, phase shifts (reflecting the degree to which a speaker's impedance is capacitive or inductive at various frequencies) are a key factor in how difficult a load a speaker presents to the amplif... | |
| tube watts vs transistor watts? An excellent (although unnecessarily lengthy) thread on tube watts vs. solid state watts, from last March, can be found here. Several of our most knowledgeable members contributed some good insights, some of which (mainly on a theoretical level) h... | |
| Do power cords make an audible difference? A friend of mine told me that if I could not hear the difference of a power cord he loaned me, my system could not be high end. Maybe he was right. I didn't hear any difference.IMO it is a common fallacy to assume that system quality and musical r... | |
| Do power cords make an audible difference? Sebrof: Tuesday night I was wearing blue jeans and my system sounded very good to me. Wednesday night I was wearing slacks and it sounded just a little better. I do not conclude that slacks make my system sound better.For a specific example that s... | |
| Cable Options from Breaker to Receptacle My suspicion has been that the power cords and cables that utilize a multitude of separately insulated small gauge conductors have been inspired by Litz wire, which is a technique that has long been used in high frequency applications, transformer... | |
| Cable Options from Breaker to Receptacle Stranded wire, especially a twisted lay, will pass high frequencies better, exactly what you don't want to do with 60hz ACJim, even though this comes from a fairly distinguished source, I'm not sure it tells the whole story. Assuming the power amp... | |
| gold lion 12ax7 , au7 Its all perspective, and it drives me crazy sometimes, I have RCA cleartops , bought them from rogue, the test well but are bright and edgy in my system. I dont like them at all. I've been wondering if a factor that might contribute to the variabi... |
