the 4 ohm rating
Bigjoe,You are drawing incorrect conclusions.For one, the requirement for an 8 ohm load as opposed to a 4 ohm load is a constraint on the speaker designer. All product engineering and design is a series of trade-offs.By placing this constraint on ... 
"High Current"
Sean,I really have to disagree with your remarks on the KrellFPB-300cx. [ Are you sure you are familiar with the "cx"variant?]I have access to some pretty sophisticated test equipment -with pico-second resolution - and the Krell 300cx matchesits f... 
"High Current"
Gregm,The Krell Class A "Full Power Balanced" cx-series "double-down"all the way to 2 ohms.Take the "baby" of that line-the FPB-300cx: 300 wpc at 8 ohms,600 wpc at 4 ohms, and 1200 wpc at 2 ohms. See:http://www.krellonline.com/html/m_ClassA_p_FPBs... 
Why do my speakers "POP" when I turn off preamp?
Jea48,The input impedance to an amp is quite high. Therefore, itdoesn't take much signal for the amp to see it.If you install a shunt - or even if you try to short the output - that shunt or short is still in parallel with theamplifier input. [ An... 
Why do my speakers "POP" when I turn off preamp?
Dawgcatching,When C-J wrote your manuals, perhaps they were assuming thatyour C-J tube preamp would be paired with a tube power amp,and that your SS power amp would be paired with a SS preamp.That way, your tube power amp would be powered down [ t... 
Krell FPB 200c lack of Power?
Xupakabras,Arthur [Aball ] is correct above.The volume control is NOT a power control - it's a GAINcontrol.An amp like your Krell can both be more powerful but haveless gain than an other. As I recall, Krells have a gain of about 25 dB. There are ... 
Why do my speakers "POP" when I turn off preamp?
Dawgcatching,When you shutdown your preamp - it's circuitry goes througha "shutdown transient". That is as it loses power, the circuitry goes through a type of "death throw".Some amps and preamps have a "muting circuit" to disconnectthe output bef... 
Ok it is time for my dumb question on the day
Harnellt,Think of it like the "cruise control" on your car.You set your cruise control to 45 MPH, and your car isstarting to climb a hill. It will naturally tend to slowdown going up hill. The cruise control will open the throttle to produce more ... 
Is a pre/pro considered digtal or analog ?
Saki70,A component is "digital" or "analog" depending upon what typeof signals it handles.A run of the mill "preamp" with analog signal in, and analogsignal out is definitely "analog".A DAC with digial in and analog out - is "digital"A pre/pro has... 
How do you shield a Center speaker?
I have to agree with Merganser.It's difficult to "shield" magnetic fields.The bucking magnet solution is probably best. From outsidethe speaker, the magnetic fields of the two magnets - thebucking magnet and the one in the speaker driver - will es... 
Krell KSA 50 vs. todays ss amps?
Dave,A well designed amp is a well designed amp - regardless of its age.Amplifier technology is pretty mature - that is it isn't like computer CPU technology where every year the processorsget better because Intel can put more, smaller, hence fast... 
Martin Logan Logos vs Theatre vs Cinema
C123666,The current Martin Logan center channels are both hybrids - just like ALL of Martin Logan's current lineup.It's difficult to make a dipole unit produce the kind of long wavelength bass sound - the fact that it's a dipole means that the bas... 
Are There Any Inherent Advantages to Class A amps?
Jeffrey,We are NOT splitting hairs - go back and read Steve's post -where he states, "Class A amps BY DEFINITION amplify through 360 of the duty cycle. Class A amps ARE NOT push pull!!!"A true Class A amp does not have two "mirror-image" amplifier... 
What is the benefit of low efficiency speakers?
Uppermidfi,There's no benefit, in and of itself, in the lower impedance.However, you have to remember that speaker design, like theengineering of anything - is a series of trade-offs and compromises.The designer may trade-off a low impedance for s... 
Major Questions Concerning Tube Amps..??
D_edwards,I don't mean to be presumptive, that DMH wouldn't understand specs. However, from reading many questions on many forums -including this one - I can see that there is a lot of confusionwith regard to specs.As you probably know, since you ...
