PRODUCT DETAILS
Matching the amp to the speakers load.
Forget wattage figures, as when it comes to reproducing music they are pretty meaningless figures on their own, far more important is the dynamic range PER Watt and then how many Watts per channel. If the dynamic range figure PER Watt is truly huge, all of the detail will be present no matter the volume level.
The lower the noise and distortion(s) 'floor' is then the greater the signal dynamic range PER Watt will be and the more natural and lifelike and louder it sounds, it's also exactly where all that finer low level detail is buried.
On both amp designs the HT power supply noise will be around minus 138 db, this is not including the valve circuits 'natural' added rejection figure. The Lithos regulated input and driver stages ( and active valve bias control circuitry) greatly exceed the HT rejection figures!
You need to know the minimum impedance figure your speakers provide as what they don’t tell you is the normally quoted 8 Ohm 'nominal' speaker you own, may well dip to below half that figure, or worse!
It's ok though, as the hifi industry (no names) has been getting away with that one for many years now. Well at least we can provide you with a design solution for resolving that industry wide speaker design issue.
If you are like us, and just want the music to sound as real as can be, you are not going to get the desired end result with the way the current amp / speaker interface has been dealt with industry wide.
Pretty much all power amplifiers on the market are of the voltage feedback type as both of ours are, the lower a speakers nominal impedance figure, the more voltage feedback is needed to drive the load, the more feedback used the worse it will sound!
