D-SONIC SOA Class-D Core Amps. The best Class-D ?


Owner/Designer Dean Deacon of D-Sonic in Houston in recent months dropped using the B&O ICE amps which he now only uses in the surround channels of his multi-channel home theater amps. He now uses a new Class-D amp in all of his Magnum2 mono and two channel amps which he states is the most technically advanced Class-D amp on the market, called the SOA Class-D core amps. The recent review in 6Moons of his new M2-1500M amp concludes its the closest that Class-D has ever come to tube amps in the upper mid-range and high frequencies.
Anyone bought or heard recently the D-Sonic M2-1500M or the M2-600M? What are your opinions?

Thank you Tan, please keep us posted as the sound of your D-Sonic amps evolves...

... Meantime Tim, what's new with your quest?

G.
Thank you Timlub, I suspected that much... The newest generation Class D modules are late bloomers as much as the previous designs, but... when new generation class D amps come into full bloom, marvellous things are often heard *grins!*
Hi Noble Tim.... Yes, wrong thread, but... Right Tim!

How are things moving along with your Anaview/Abletec1000-1300 amps to be?
Hi Dennis, as you can see, there is a little bit of uncertainty in the common lore about the specs of D-Sonic's fine amps. If you can add a little bit of technical information on your site for each model... such as available module options, the confusion will vanish quickly.

Hi Tan43, how many hours -- with a signal going through -- do you have on your amps?

Guido
Hi Tan43, your D-Sonic amps are likely to continue to sweeten for another 700 hours or so... Do keep us posted on their progress. G.
Hi Tim, this delay must be very stressful... In case you ever opted for a pivot, NAD Electronics has just released its first Masters Series stereo amplifier based on NCore technology, priced at an attractive $3K. See:

http://nadelectronics.com/products/masters-series/M22-Stereo-Power-Amplifier

At least on paper, the device looks very interesting... It uses the NCore module as a subcomponent of a fairly sophisticated circuit, not as an all-in-one amplifier connected to I/O terminals.

Don, you can expect break-in to last anywhere from 600 hours to 1500 hours with your new amps.... Initial performance is almost always limited in the treble region. During breakin, performance is expected to fluctuate wildly, and become occasionally bothersome... but performance will trend upwards in the longer run and anomalies will disappear.

A popping sound on power up is common with amps that do not use a soft start relay, and a clicking and slight popping is also possible when you rapidly increase volume on the pre, particularly when approaching or passing beyond unity gain... Good idea to check in with Dennis though.

Mikela8, if you contact Dennis at D-Sonic, he might tell you which modules are being used in the amps. G.
In general, as class D amplifiers are 85% to 96% efficient, they run cool to moderately warm to the touch. There are few exceptions, like the Rowland Continuum 500 -- since withdrawn, which are toasty to the touch.
