George,
You seem to misunderstand how amplifiers work. Take your ML2 monoblocks. They put out 14.14 volts max to make their 25 watts at 8 ohms before clipping. At 8 ohms, they are flowing 1.76 amps of current. At 4 ohms, they are still at 14.14 volts, but 3.53 amps of current. 2 ohms, now up to 7.07 amps and 100 watts of output. We will ignore anything below that, as the CS5s don’t dip below 2 ohms until the subsonic range (and even trying to put 100 watts through the 8" woofers below 20hz will cause them to exceed their excursion limits).
Now lets take a Class D amp, say the Ncore NC400 for DIY. It is rated at 200 watts at 8 ohms, 400 at 4 ohms, and 580 at 2 ohms. It has a maximum current capability of 22 amps per the manufacture. Lets only run it at 100 watts into 8 ohms, where it will be 28.28 volts and 3.53 amps. 4 ohms, still 28.28 volts nets us 200 watts, and 7.07 amps. 2 ohms, still 28.28 volts, 400 watts output, now we are at 14.14 amps, or twice the current of the Levinson and still well under the manufacture's limit of 22 amps.
An amplifier doesn’t put out more current than a speaker needs to reach a set voltage. The Ncore will maintain twice the power output as the Levinson down to 2 ohms (and below even). These are the laws of physics and why amplifier designers speak in terms of voltage, not current capability, except to establish the minimum impedance a given amplifier maintain its voltage. Put another way, even a cheap receiver can drive 2 ohm speakers, but will do so at a far lower output than at 8 ohms.
