D-Sonic vs Wyred vs ....

Patrik Bostrom, Chief Engineer and designer of Abletec Amplifiers that are used by D-Sonic, has done away with PWM,
[Pulse Width Modulation} in his Class D designs, which has always had problems with uneven harmonics in certain bands and uses a method he designed call Phase Shift Modulation, which is similar to the method designed by Bruno Putzeys with Ncore/Mola Mola. However, Bostrom has the edge
after reading up on their design applications and Bostrom currently has made the worlds finest Class D amp for Marten of Sweden, Their M-Amp. PWM is still used by B&O in their ICE amps and has been around since the first Class D amp was invented by the Fairchild company in the U.S in 1964.
A mono amp, the Fairchild UA-702, which never got off the ground due to constant failure. That same year, Clive Sinclair in London, launched the worlds first working class-D amp which also had its problems. Patrik Bostrom with Abletec, is also a
musician and a very passionate Audiophile. Abletec is more advanced than B&O. Better bang for the buck.

Hey Viggen,

Since you mention Infinity, I have a pair of Gilmore Raptor monos on the 'Gon right now. These are 500WPC ClassD amps using modified high sampling rate ICE modules. I've been running them for a few years on my Infinity RSIIb speakers and they sound great in that application. I built monster transmitter tube amps in the meantime, though, so the Raptors are up for grabs.

Just thought I'd let you know.

thanks for the heads up on your stuff.... I am just worried that wouldn't be enough power for my speakers. I hope to snag some better sounding speakers some day, kappa 9.1, ren 90's or one of their larger speaker systems and am worried 500w at 4 ohms will not cut it

Has anyone purchased from d-sonic? I have sent them a email from their website and no response for over a week now. Between that and their website being kinda funky.... its making it harder for me to send money their way. Are there any other manufacturers which are of similar cost and quality that I am missing?

I usually prefer to call manufacturers by phone instead of sending emails.... Try calling Dennis at 800-862-7998.

You might have better luck than by email. G.

For the last four months I've had a D-Sonic M3-3800 5 channel amplifier in my rack. The front L/R channels are 1000 watts each at 8 ohms and the other three channels are 600 watts each. The sound is impeccable with all sources.

This amp replaced a W4S 7 channel amp that was rated at 250 watts per channel at 8 ohms. It also sounded impeccable with all sources.

I didn't use two of the channels on the W4S amp and figured it would be nice to have more power running through the channels that are active.

Didn't have the opportunity to A-B the two amps but I think it would be a struggle to describe any material difference were they volume matched for a comparison. Both are excellent... my recommendation is to let your power and budget requirements guide your decision.
