D class amps with Soundlab speakers

Sound Labs do play nice bass. The trick is if the amp can deliver power into the bass frequencies as their impedance can be quite high. This is why they seem very power hungry if you have a transistor amplifier- an amp that makes 400 watts into 8 ohms will only make about 100 watts into the bass frequencies.

Its not a power issue though- 150 watts is plenty of power if the amplifier can make the power. Its a matter of impedance.

Dob's description matches pretty well to what I hear with the IcePower Bel Canto ref1000m monoblock Class D amps in my system. They seem to work well with most any speaker design it seems though if your speakers are a bottleneck to the sound, you will know it.

Yep, its better to be rich and healthy then poor and sick.
The problem is that some, just some don't know how to reach there.

IcePower and Soundlabs: Honestly, I am not even sure if these amps are capable to drive these speakers without invoking protection circuitry... Very easy to test; if in the middle of music you will hear silence then yes, its your answer

For the most part solid state amps do have trouble making power on this speaker. I would not expect a class D amp to have problems with the load otherwise, just that you would want one with a lot of power (600 watts or more depending on the room) so that you don't have to push the amp.

Some of this is my own experience- I find that class D works a lot better if they aren't being pushed hard.

"I find that class D works a lot better if they aren't being pushed hard."

PRobaly true with most any SS amp but honestly, I play my BC ref1000m's pretty loud on some relatively inefficient speakers (albeit not electrostats, which are unique electronically) in a decent sized room and I have never detected them being even moderately warm, much less break a sweat. THey seem to handle things without much effort for the most part no matter what. No sign of stress or rough edges in the sound whatsover no matter what. Has not been the case with any other SS amps I have used there, which is one big reason I went to one of the biggest yet most efficient, well reviewed, and tube pre-amp friendly SS amps I could find. I had to stretch a bit to handle the cost but it was worth it.

I have heard other IcePower amps (Rowland) do a similarly nice job with Magnepans however. I can't imagine that a good design that addresses power supply around a stock Icepower amp module like these could not handle just about anything. I might be somewhat more skeptical about some amps that just stick stock Icepower modules in a box but I would expect decent results even there.
