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

Uhrn Audiozen, thank you for the staggering faith you have in the financial import of my scribblings... Regretably, my labors of love on PFO are only fit to fund tasty yet conservatively priced sushi rolls dinners three or four times a year, during 50% off days, for Mrs. C. and I. For the more mundane purpose of making a living, AT&T keeps me happily busy full time on arcane matters relating to FCC/CVAA.

In answer to your question, The lowest cost amp review project that I decided to submit for editorial review and eventual publication on PFO is the Bel Canto REF500 mono. A hypothetical D-Sonics project may be an interesting addition to my candidate queue. Conversely, I hope that you will share your findings on your very own D-Sonics amp with us before long.

Here is a question... D-Sonics appears to utilize both AbleTech and Pascal.... What criteria does D-Sonics apply when selecting between one of these two core module suppliers for its amps?

First Guido..pardon my assumption referring to you as a full time reviewer. Why Dennis uses both Abletec and Pascal is for one reason only, sheer power from the Pascal
and high power from the Abletec for most speaker applications. The ALS amp in the M3 600M and the M3 1200S is the most powerful amp from Abletec. The Pascal amp puts out much higher power and Dennis only recommends the Pascal in the M3 1500M for the most extreme speaker applications if you have a King Kong speaker that really needs that much power. The Abletec amp he uses sells more than the Pascal. The chief designer at Abletec, Patrik Bostrom, whom I discussed in a previous Gon thread, has developed an application called AMS,(Adaptive Modulation servo),which is a new loop linearization technology that is very similar to the application designed by Bruno Putzeys in his Ncore NC1200 amp. Both their applications resolve and eliminate the problems with past Class D designs such as phase shifting, feed back, distortion and noise. The Abletec provides a much larger power supply than the Ncore SMPS 1200 power supply for the NC 1200.

Thank you Audiozen. If I interpret correctly, D-Sonics may be using Abletech when maximizing a design for musicality; conversely, they implement with Pascal when maximizing for power... Is this more/less correct?

Could you qualify the term "much larger", and explain "application"?

G.

Audiozen, which class D amps have you really listened to? Have you actually listened to the D-Sonic and Ncore amps?

Guido..I meant much larger power output then the Ncore set which puts out 1200 watts into 2 ohms and the Abletec puts out 2000 watts into 2 ohms. Application refers to Bruno's non linear design and Bostrom's ZVS (zero voltage switching) and his ADP,(Adaptive pole control)with his loop lineariztion technology. D-Sonic does not favor the Abletec over the Pascal for musicality in their models. As you are aware, Jeff Rowland is using a Pascal amp in his Continuum S2 integrated amplifier. The review on the D-Sonic M2 1500M amp using Pascal, in the September 2012 issue of 6Moons is very positive. Based on the tech sheets provided by Abletec, the maximum damping factor of the ALC 1000M amp used in the D-Sonic M3 600M and 1200S is 4000.
