What an insane response to the AVM C9 review, which was quite polite actually. I mean really, a class D flea weight integrated that get's fairly decent marks and they go ballistic? Of course it's gonna sound a little shrill...it may even suck for most people. For the money it is a completely insane offering. Modwright offers a 200/400 watt integrated with DAC and Phono for about $6500 and is near state of the art...do the math.
It was actually a spot on response to the review. I own an AVM C9 and I run a pair of Majico speakers with it and I can reassure you that the reviewer was drinking koolaid!
There is poor quality Class D and there is superb Class D. The C9 is remarkable. As far as an insane offering, well let's see, Phono, FM, Full DAC USB 24/192 Async, Excellent CD Player, HT bypass, 325 Watts RMS, Made in Germany at a retail price of $5700!
Modwright state of the art, on which planet or galaxy - are you sure about that?

But note the truncation of 24-bit audio on the digital input, the high jitter, and the modest measured performance with CD-quality digital sources.

The amplifier section does measure well for a class-D design.
As far as an insane offering, well let's see, Phono, FM, Full DAC USB 24/192 Async..
Our sample's USB input operated in isochronous adaptive mode, not asynchronous, and was restricted to 16-bit data and sample rates of 48kHz and below.
Excellent CD Player...
Not according to its measured performance.
Modwright state of the art, on which planet or galaxy - are you sure about that?
Modwright uses, IIRC, the Hypex class-D modules, which are excellent.

1) The CD section as measured by HI FI Plus was and I quote "top category"
2) The AVM C9 that I own has the USB input asynchronous, 24/192. Excellent.
3) The AVM C9 also uses, IIRC, the Hypex class-D modules, which are indeed excellent.
You did know this?

Our sample was not excellent.

Our review sample's USB input operated in adaptive mode and was limited to a 48kHz sample rate.
3) The AVM C9 also uses, IIRC, the Hypex class-D modules, which are indeed excellent.You did know this?
No. But as I said above, the amplifier section of the C9 did measure well for a class-D design.
Overall, it appears that the design of the AVM C9 changed after we received our sample for review, particularly regarding the USB input. However, we can only report on what we have in our possession, not on what might happen to the product in the future.
