According to the manufacturer, they still use ICEpower modules and have product/s currently in development that will use new ICEpower modules that have now been released.

Is there any merit in buying DIY modules, mounting them in a case with some simple hardware and selling such a product as if it was some ultra-sophisticated audiophile thing?

Such manufacturers are not actually manufacturers but bare amateurs without a clue about circuit design finding their way to earn big money.

It's all a load of B.S. They will be bare amateurs until they become able to develop their own high performance class D stuff from scratch.

I have a three a yeard old brother that will become capable of wiring a DIY module to a transformer and a pair of capacitors quite soon...

Are you refering to this statement?

I think it's OK to buy highly advanced modules and package them, nothing wrong with that. It takes some skills to marketing also, not everyone are made for that.

Isn't this a nice implementation of the Hypex modules?

Question: How many of the high-end customers know about electronics? <1% or less, am I wrong?

Hi

I've also read the glowing UCD review from TNT. I'm clueless when it comes to sand electronics but this caught my interest... I see that it uses an Opamp (from various makers as option) input buffer, but the Analog-Research website above states that they use a Lundahl Input Transformer (switchable taps) then a Jfet buffer. The question is if anyone tried to do a something similar with Input Trafo but Tube buffer (if possible)? Making it sort of a hybid amp?

BTW, I saw this output cap (custom Auricap) upgrade for Ucd400/700 recently:

http://www.diycable.com/main/product...roducts_id=593

.. but I think any radial leaded polyprop/foil type cap will be a good replacement if it has he same lead spacing as the stock one w/ the approp V rating. The stock one looks like a polyester cap, but not sure about this. I'm not into boutique parts but are the lytic caps in the module long life / low esr types?

no self-respecting manufacturers would do that.

However, Class D is a gold-rush now and if foolish people want to part with their money so eagerly, who are we to stop that?

Probably, "Jocko Homo" uses Ice modules in his products and I think he also uses Hypex and you can read what he thinks about his products.

However, in the past, Class D operation was not regarded as being worthy of audiophile consideration. With the new generation of Class D amplifier modules, they now are a serious option for audiophiles. We are pleased to be among the first to produce products using these new technologies

peranders, did you test UcD400 with factory dead time pot position? I've tested UcD400 1-1.5 year ago, and they gave same THD as in the review, but not at factory position.
