I think that the C1 offers a lot for it's size and can be "hi fi" sounding or relaxed given the upstream components and it is certainly the more forgiving of the 2. C1 does sound terrible at low volume and I had some serious gear behind them. Crank them and they are certainly more of a party speaker than the magicos.I agree regarding the low volumes. The originals need to be cranked up to sound their best. That being said the MKII is great at all levels. Yes I upgraded from the originals to the Signatures.
Noel if you like the Dyn sound have you considered the Special 25's or the Sapphires?
