Mr. han_n
I'd call CH Swiss to check about your M1 Amp.:
" Dear Michael,
Thank you for your interest in our
products.
The damping factor of an amplifier
being the ratio between the connected loudspeaker's impedance and the
amplifier's output impedance, we can not publish a single number.
We would need to publish a damping
factor for each possible load (like any amplifier manufacturer should), but
also for every setting of global versus local feedback ratio of our amplifier
(which is user-adjustable on the fly from fully global to fully local, with 9
evenly-spaced steps in between), as this setting has a direct effect on the
M1's output impedance.
At full global feedback, the M1's
output impedance is measured at 0.013 Ohm. So in a 8 Ohm loudspeaker, this
means a damping factor of 615.
At full local feedback (no global
feedback at all), the M1's output impedance is 0.09 Ohm. So in a 8 Ohm
loudspeaker, this means a damping factor of about 90.
As a loudspeaker cable of a few
meters probably has an impedance of more than 10 mOhm, it might actually have a
dominant effect compared to the amplifier's output load, at full global
feedback.
I hope this answers your question.
Best regards,
Loris Stehlé"
If we go for the best I would say that the M1 \'s DF is >500.
But when I looked into your speakers: Gryphon Pendragon
http://www.gryphon-audio.dk/media/1408/manual-pendragonv2.pdf
I found that the bass unit is self amplified by a 1,000W amp. It is connected to your Pre. by XLR and no speaker cable is required.
The Mid/High unit is a ribbon. So a regular wire (12 AWG would do). Even thou your system is very expensive, you can save big on the cables. :-)
The Bi wire - Bi amp on the Gryphon Pendragon
Mid/High unit won't give you any improvement. only cost way more, if you think of another pair of CH M1's ($37,000.- each).
