Oh how I wish Class D amps ...

There is no signal processing since most of class D amps are analog. As for the Zobel - Yes it is choke and output resistor and capacitor. Icepower calls it Zobel.

Excerpt from datasheet of Icepower 200ASC and 1000ASP modules:

"Due to the compensating Zobel network in the output stage, the maximum allowable short-term output power
is frequency-dependant."

I have heard many Class D amplifiers, the latest Nuforce can seriously challenge many, really expensive conventional amplifiers. Nuforce are the only switching amplifiers that I have heard that have a liquidity and presence in the midrange that rival really good conventional amplification.

I have heard the Bel Canto and other Ice amplifiers which sound much more hifi than the Nuforce.

If you haven't heard the latest Nuforce you should listen to a pair you will be convinced that these types of amplifiers have real promise.

Hello Kijanki,

I wish to apologize. I have had no idea whatsoever that ICE Power uses Zobel network. I don;t want my words to be iterpreted as even slightest critic of our competitor.

Still, for the record (and from our web site):

" Spectron designs team won a contact with pro audio giant Inter-m (among others in competition were Bang & Olafson and Philips)..."

Inter-M may be the biggest pro audio company and we are proud, as small team of 4 design & 1 production engineers, to have our design to win against somewhat more resoursful Philips and B&W ...but music lover have right to choose and be happy with any design they choose. Its a given.

If I offended someone - my deepest apologies again.

Regarding "There is no signal processing since most of class D amps are analog "..... before digital signal there was and still is analog signal which people for 100 years processed: from simplest as adding to most complex. Even computer does not need to be digital; some early computers were analog.... making my living for 30 years from digital signal processing I better know what I am talking about.

Respectfully,

Simon

Audiofreakgeek : I was loaned a Nuforce Reference 9 V3SE to audition, and found it rather dull in my system. Definitely a lack of air and extended highs. JMO

We should never underestimate the importance of system synergy and how some components are not a good match. Timtim, maybe a more appropriate elaboration would have been "Oh how I wish Class D amps would be a good synergy with my Vapor Cirrus speakers" :-)
