Hy,
I too have the Marantz pm6004 amp, getting the same Kef Q300 speakers soon.
Here's my take on the Dac situation as I almost bought the Cambridge Dacmagic I started to wonder...
would you really spend 300 on a audio "converter" your amplifier costs that much!
Now, I'm guessing you're connecting it to a pc/laptop.
At the moment I'm using the Iconnex Usb Soundcard, (
Products - iKey Audio) which was recommended to me by a specialist retailer. What it does, it gives a line level output to the apm bypassing the on-board soundcard of a computer.
The beauty of it is that it only costs 40 euros.
The sound can not be made better by up-scaling the bit rate or sampling rate.
It can only be as good as the source. What could the Arcam rDac do with a 16-bit 128kbps mp3? Nothing. And would you need a 300 hardware to play your flac music which is 24-bit in depth and goes at 999kbps?
I agree that Dac's make the music sound different, but is it really improved?
Think about that.
To give you a paralell example, you take a picture with a 0.9 megapixel camera, and try to zoom in on it, you wont get far until you can see the pixels. That is low resolution, now there's no software or hardware on earth that can make your low resolution picture razor sharp poster sized.
But take that picture with a 20 megapixel camera, and you already have a poster sized picture. It's high resolution.
So, the source matters the most imo.
ps. what stands are you using with the Kef's
Regards,
