Well, I've had my CDQ for quite a while now, and thought I'd report back on how things are. Some of you may not be interested, but some of you who are deliberating over purchasing, may be.
I now have my 8000LX configured in power amp mode, so I now have the CDQ operating in full pre-amp mode. As a CD player I am thoroughly impressed, it's digging up detail, and delivering music to my ears in a way I have not experienced in my living room before. It makes me want to listen to all my CD's again and again, and is helping me rediscover some underplayed albums, surely no bad thing. I haven't fiddled around with the filter settings much, and to be honest, I haven't been able to detect an awful lot of difference between some of them. But, much like the majority on here have stated, the optical transient, and the XD version, are probably favourites. The CDQ replaces a 63 KI Sig.
I have a Squeezebox Touch attached via optical, and this generally gets used late at night when the effect of alcohol has reared it's ugly head, and is controlled via iPeng. Patience isn't one of my stronger points, and the convenience of this set up is very useful to me, but does lead to long nights with little sleep! From a critical listening point of view, to be honest, it sounds no different to the Touch's built in DAC to my ears.
I have also used the USB DAC via a laptop running JRiver Media Center with WASAPI (whatever that is), the result of this is pretty much the same as playing CD. The sound is far superior to that of the Touch using the same FLAC files, it gives a more dynamic sound, better soundstaging and more realism. It may even sound a little better than direct CD at times, dare I say?
Yes, the tray might be flimsy, and yes, I probably will like to get the software updated, but the main thing for me is, my music has never sounded as good, and as far as I'm concerned, I have achieved this for a very reasonable amount of money. Now for those monoblocs.......
I would also like to take this opportunity to thank John for the care and consideration he has put into these products, and his customers, and please accept my condolences for your loss.
