Maybe someone will do a translation to english when it is published?

Note that the Tripath & B&O use the "Red Amindon type 2" inductors - also second sourced by others (Micrometals).

The tread from the Swedish DIYforum is about a blast among ClassD amps.
The blast is to be during november and will probably sort out a "winner".

I have listened to a friends UcD180 and compared it with some other amps.

It sent a Bob Carver Sunfire stereo amplifier to be ashamed in the corner. The UcD had so much more 3D and no distortion.

It formly crushed a Vincent sp331 amplifier. The Vincent was found having exagerated bass and treble and the bass produced was cloggy and indistinct. The vincent belonging to the same guy that owns UcD sold the vincent the day after the listening session.

Compaded to my own Musical Fidelity X-A1 the UcD was superior in every aspect, but the X-A1 did a far better job than the Vincent.

Another friend has evaluated the UcD against Sentec PA9 mono amps, and his conclusion was that the UcD did everyting the PA9 does with magic even better.

Im ordering my pair of UcD400s tomorrow and Im aiming at having the amp completed before x-mas.
The UcD is one of the best amplifiers i have ever heard. It works extremely well with Carlsson speakers.

opps.. long post for beeing the first...

Best Regards,
Pontus

Hi,

I can't read swedish either, I trust the one with the big ugly IC is Tripath right? Looks like that's their input stage.

Many have made that direct comparison already. Seems the ZapPulse is still an excellent amp but the UCD generally comes out ahead for a few reasons.

Exclamation Be aware!

I have heard & tested several pwm/"digital" amps, and have found one thing common: in a short listening-session/blind-test, they all "bloom", but I have not been able to live with any of them for more than a week...
My N-channel always finds it's way back...

Hello,
I'm a newbie and have been following this thread with much interest.
I have some questions for the experts.
Is there something to be gained sonically using two transformers instead of one?
About caps ichoice: PS: Black Gates are very expensive, Cerafines are hard to find, what about Jensens 4-pole?
How better AD8620 really is instead of the standard OPamp?
And last: this is going to be my first DIY project, how difficult is it really?
Thank you very much
