| Mosfets: The way to go for SS amplification? "I've done a "search" here and elsewhere and not gotten a good answer as to why it may be superior to JFET"You need to seek out some good books on the subject and explore the facts on your own (that would be my definition/approach of getting a "go... | |
| A few questions about DAC basics "Does the DAC connect to the preamp via analog in or digital in to the receiver?"Analog in--hence digital-to-analog conversion: signal goes in digital, comes out analog."I am also assuming that the DAC handles the digital signal in such a way as t... | |
| Need suggestions for small room speakers That's really small! Maybe headphones? Ok serioulsy, my long 2 cents: if big bass isn't a priority, a nice pair of 2 way mini-monitors with 6.5" drivers should be more than enough. Even a 2 way with 5.25 inch mid/woof will probably give you some g... | |
| Quality of Stereophile Class A speakers at 2K? I haven't looked at Stereophile in years--and seeing what comes up about them I'm not missing much. I thought their definition of Class A was "state-of-the-art." Class A restricted LF meant that definition minus that last octave of bass. I'd give ... | |
| Two Amps One Pair Of Speakers This is why you remove the jumpers when you biamp: so they're not connected anymore. | |
| Two Amps One Pair Of Speakers "Even in cases where someone bi-amps in a single system, there are two amps driving the speaker which in many/most cases is connected internally via crossover - regardless of how many binding posts are on the speaker."I don't think anything's "con... | |
| Class A, B, C? What do they mean? http://forum.audiogon.com/cgi-bin/fr_srch.pl?&1&procsrch&3&4&The first five or six hits cover you question in various ways. Search "class" in the archives if the above doesn't work. | |
| Class A and B differences? I retract partially--you may be right on the Class AB. But they both seem to be of the impression that to quote "Class AB is less linear than either A or B" and "is not really a seperate class of its own..." Or "Class B is by far the most popular ... | |
| Class A and B differences? "but when you mention class B I believe you are refrring to class A/B."No, I think he's right. "Class" A/B (althought there are plenty on the market) really isn't a class: its an amplifier that goes from class A mode into class B mode when the pow... | |
| amplifier's "slam-factor" An output impedance of 2 into an 8 ohm load gives a DF of 4, not 2 as incorrectly stated. (This is ignoring the change caused by the cable) Although if you look at tube amp specs you'll often see ones claiming DF's of <2. I believe the Cary 300... | |
| amplifier's "slam-factor" Aball, the damping factor is calculated by dividing the resistance of the speaker by the output impedance of the amplifier: DF= Z(load)/Z(out). For an amp to have a damping factor of 100 into an 8 ohm load its output impedance would have to be .08... | |
| Someone explain human hearing of subbass...... "Is our hearing not as sensitive to subbass frequencies at low volume?"In a way, you're getting into what is called the Fletcher/Munson Curves. The "loudness" switches can't do a very good job at it do to the variations in LF performance in loudsp... | |
| Should Class A Amps be left on?? From "Audio Power Amplifier Design Handbook" 2nd ed. by Douglas Self page 362 final paragpraph:"Readers of hi-fi magazines are frequently advised to leave amplifiers permanently powered for optimal performance. Unless your equipment is afflicted w... | |
| Budget system not up to expectations... "Sadly, I think the Onkyo/lampcord sounds slightly better"It might actually. I tried the AP oval 9 a couple years ago in my 2ch system that was about $10k then (Hybrid tube/ss circuits). It didn't do anything performance wise and I went back to my... | |
| Build me a killer Rock/Metal Rig for 1K I read'em all; alot of people here have certainly put forth some effort. I'm not going to tell him to bail since he does have to listen to something. The Aragon hifiguy recommends is a good choice. I'm not big into balancing the coloration "du jou... |
