This qualifies as an exciting addition to the Class D amplifer list, so thought I'd add it here.

This amp will be mated to my Ascend 5-channel setup.
I will keep all interested apprised of my kit build progress, likely in another thread.

Interesting mini-review here with this author stating that the amp supersedes his existing Odyssey Stratos, which I think is no small achievement.

Best,
Adam

Quoting myself because well, it's easy. So, I'm utterly embarrassed to say that I *just now* hooked this puppy up after moving across the country with it, getting soldering help from a friend, and replacing a quick fuse. To my ear-to-ear-grin surprise, I hooked the thing up perfectly. And OH MY was it worth it.

This amp replaces a Denon AVR-2801 powering my Ascend Acoustics setup, and I am still just sitting here, listening in awe. Can't really believe I paid what I did for this highest of high-end machines, and put it together myself.

Bravo Kevin, BRAVO!

Good news for Curtis: I'm in Santa Monica now bud!

Feel like a listen?

Best,
Adam

nuforce debuted their new micro 10Wpc integrated amp at CES 2008





downside is needing to crimp the speaker cable, but the package will come with speaker cables terminated with the appropriate RJ45 jacks

Hey Fumac!

Nice to see you here on avsforum. I spend a little time here myself.
Talk to you later.

I've also been looking for a "digital" amp hopefully in a receiver. Other than Panasonic, what are the options ? I have a few reasons for wanting a receiver.

I don't have huge speakers (orbs) and don't need 500w/ch.
Seperate processors seem to be big bucks whereas fairly sophisticated receivers (say the Denon 3808ci) are around 1K with all the processor features I need such as single HDMI connections for multi channel sound, streaming audio from ethernet, latest audio/video encoding etc.

Can anyone recommend a good/cheap processor ? Seems like for most of these setups, even if I get a reasonably priced amp, I've still got to shell out for the expensive processor. Or do folks use a receiver and just send the audio-out to an amp. I noticed that although Onkyo has this digital amp, they use a/b stuff in their receivers (which run extremely hot !)

Also seems like you must lose SOME sound quality converting D/A then back to D when you have a digital source but a separate amp with regular analog inputs. Maybe that's not too big a deal but if these amps are so small and efficient, I'd just assume have them in one box.

Fumac,

Any place to check out and buy amps based on your technology?

I'm just a caveman. Your modern world frightens and confuses me.

fumac,

From your web site it sounds like your intention is to OEM them.

Are these available in any products yet?

I'd be interested in a 7-ch amp.

I didn't see it mentioned in this thread. You might want to add it to post #1:

Axiom (www.axiomaudio.com) A1400-8 ICEPower 8x200w www.axiomaudio.com/A1400-8.html

The Axiom A1400-8 Amp AVS thread is discussing it in more detail.

Pioneer's flagship A/V receiver, code named "Susano," has set the industry standard for home theater performance and its 2008 top-of-the-line receivers, the SC-07 and SC-05, continue to incorporate the Direct Energy HD Amplifier with ICEpower analog class D amplification technology to produce a level of multi-channel power output, fidelity, and efficiency never before seen or heard in a home A/V receiver.

DENON DRA-CX3

Not sure if this new AMP/Receiver is PWM from Denon, but it looks like it might be. Does anyone know anything about this?

August 2009 - Bryston goes class D - Bryston, LTD has announced that the first two of four new 8-channel zone amplifiers will be shipping to dealers by October 1st, 2009. The Bryston D-Series D-130Z Hybrid [$4,395] and the D-250Z Hybrid [$5,695] have been in development and many dealers expressed the need for a lightweight, high performance multi-channel amplifier for distributed audio and industrial applications such as bars and restaurants. Bryston uses the term hybrid in reference to the combination of class D amplifier technology along with a Bryston-engineered linear power supply.. "This is what our dealers have been asking fora multichannel solution built to Bryston standards," said sales VP James Tanner. "Although the D-Series is lightweight, highly energy efficient and cost-competitive with other multi-channel products, these amplifiers also feature input stages and power supplies designed by Brystonthese are world class audio products, Tanner stated. The Bryston D-Series is a reliable amplifier solution with low heat emissions for tight space applications such as the equipment racks and utility closets commonly found in restaurants, bars and nightclubs. Unlike most competitive industrial amplifiers however, the D-Series carries on Bryston's tradition of sonic excellence and durability.

Product Specifications:

D-130Z Hybrid Features:
Bryston engineered 2 x 650 watt linear power supplies
8 independent channels at 130 watts each into 4 ohms and 90 watts at 8 ohms.

Soft-Start circuit to prevent high power in-rush current
Gold plated 5-way speaker binding posts
5 year warranty
Dimensions: width 19 x height 4.125 (3.5" without feet) x depth 16" including connectors

D-250Z Hybrid Features:

New Class-D amplifier!

Arion Audio MK1000

review

Quote:
...there is no doubt that the MK 1000 from Arion Audio has all the prerequisites to become a big success and this for three reasons: Firstly they have neutrality and very low noise despite their very high power, secondly they do deliver -exactly- that high power that will free them who have a difficult loudspeaker and/or big space and third they achieve all these at a comparatively reasonable cost.




Boo!

Thread necro, because I want to know if 1) there are still new PWM amplifiers being actively developed and released and 2) if anyone has a new thread listing them or if SiriuslyCold is still updating this one.

As an FYI, this thread is also the primary reference external link on the Wikipedia article for the Class D amplifier. If for no other reason than this, I think the thread deserves an update!

Cheers,
Adam
