Class D = Trash?


So, I'm on my second class D amp. The first one, a Teac AI-301DA which claimed to use an ICE module, was unlistenable trash. I burned it in for a few weeks, it just couldn't perform, so I sent it back. Following that, I tried the new Emotiva A-300 (class A/B). It was significantly better, but lacking in too many ways for my tastes. So I changed gears, got an 845 SET from China -- and it was an immediate and massive improvement.

So, before I went further down the SET road, I wanted to try a better class D product using a modern class D module. I settled on the D-Sonic M3-800S with the Pascal module and custom input stage. I read from reviews that these things like to have big cables, so I picked up an eBay 8 gauge power cable (Maze Audio, el-cheapo Oyaide copy plugs, braided 4-wire cable) to go along with it.

Mid-range GONE.
Soundstage depth CRUSHED.
Euphonics DISAPPEARED.

Yes, resolution went up. Driver control went up, allowing me to play compressed rock/pop and orchestra with the speakers being able to render it all. But enjoyment in the sound is basically gone. Using my best power cable (LessLoss Original) improved performance, but didn't fundamentally change the amp's nature. I ran back to my headphones (Focal Utopias) to detox my ear canals.

So, how long does a class D need to burn-in? I want to give it a fair shake before writing the technology off forever.

Hi George, it Seems that when I try to follow the links you just posted, I end up on an image instead of a regular page.... As my screen reading software cannot decipher images, may I ask you to post links to the actual pages, or to post the model of amp you are referring to?

Al, past the 500 hours mark, performance trof should be relatively minor on the Rowland Continuum S2.... Gradually, sound will continue to open up for quite a spell.


Saluti, Guido


Hi Guido, George's picture is of a JR Model 102S. Looks like it is in Sydney.

Thank you Al, Rowland M102 is the most entry level class D amp that Rowland ever created. The model is almost 10 years old, and is today hardly representative of what can be done with class D and with SMPS. M102 has been discontinued a couple of years ago, and has been replaced by the M125, which sports a much newer ICEpower module, supports bridged mode operations via a toggle switch in the back of the chassis thus delivering 500W per chassis, and contains several other technical updates. According to all 3rd party reports I heard, M125 is an exceptional little amp... Far superior to the original M102.
