damping factor and amplifiers

[Macca]

And don't forget RISE TIME! Babey Yah!

But I notice that HFW have started quoting damping factor in their amplifier reviews...

[DSJR]

They regard a figure of "50" as a high value. My amps are around 1000 (500 in bridged mode).....

Inboth my system and HiFi dave's setups, my Quad II's (with low bass damping I suspect), didn't appear to have much bass extension, sounding rolled off if anything, so *just* using one factor isn't enough..

I've also heard decent valve amps appearing to have as much "power" as a solid state equivalent with three times the WPC or more. I wonder what it could be?

So, in what circumstances would a low damping factore be required?
I ask this because some amps have switchable damping factors - 2 of mine, included.

My impression was that as a rough guide low damping factor gives 'more bass but loose' bass and high damping gives 'less bass but deeper and tighter bass'? Dunno about the valve power thing - maybe that's the slew rate in action

There were several people using Class D at Bristol. However Cass D amps can have a high, or a low damping factor depending on how they are designed.

thanks dave , i didn`t spot any .
