Difference between bridged and parallel amp?

Correct. But it's quite easy to properly parallel two amps.

That's true but the result is inferior to a single amp designed for the purpose.

I guess that depends on the THD figures and so on that you don't mind.

Graham

Agreed.

Let's hope so, or the guys at

Pricey for a 600 wpc/8 ohm amp.

Isn't that the same gif on both web sites?

i.e., red dragon audio! ;-)

Could be.

Probably. But who cares nowadays with very high quality 1 Kw/4 Ohm class D amp modules - with built-in SMPS, of course! - costing less than USD 200 in OEM quantities ?

The manufacturer... Scandinavian-based. Ice something. :-)

These modules are state of the art. A number of "audiophile" companies are using them in stock form, other have slightly customized versions manufactured for them.

The Hypex UCD modules are excellent, but don't include the (SM)PS.

Have a look at say,

That's the retail price for a *complete* amp, including case, connectors, packaging et al.

The OEM module - here a 500 w/4 ohm version - costs much less, say less than USD 150 FOB in OEM quantities.

Now a little bit of fun.

Let's have a look at the web site of a manufacturer using ASP modules:

Say, Red Dragon Audio.

Their SA 1000 is sold direct for USD 1,799 (plus tax and shipping)

It uses two 1000ASP modules housed in a very nice aluminum box fitted with sturdy sockets, jacks, binding posts and feet,, which looks identical to the Entry 130 manufactured in China and sold in North America by Digital Analogue DIY for USD 130 (Qty one, end user price).

Hmmm. Some modules - minimum order is half a pallet, 80 modules, so you have to front something like 30 G's, some nice boxes, a couple of feet of internal wiring, a mains cable, a sturdy UPS-proof box and a laser-printed user manual

Presto, a new "manufacturer" is born...

(All this in order to show that the wide availability of OEM modules will have the same effect on the audio market than it had on PC's: we'll see more and more state of the art products at affordable prices. We'll also see manufacturers trying to differentiate their offerings with tweaked or custome solutions).

Aah, are you referring to the B&O ICE modules? Proving very popular now that they've proved their chops in the Lab 5 speakers.

"François Yves Le Gal" Some pommy d*****ad

The two or more power stages are made to have unity gain - ie 100% NFB.

Then, a single voltage amp drivis them all.

Tres interessant.

It awfully looks like the same .gif.

I can't be affirmative as I've not run an ABX double blid triple Dutch test... :-)

I think it was clever how they avoided the need for a new gif by keeping the front panel clean. I do like at least a power indicator on the front panel, though. ;-)

No, they're the same, but they're jpg's. ;-)

Amplifiers run on smoke. When the smoke comes out they stop running. Very simple!
