A I said I own a Musical fidelity Kw DM System, transport + Dac. The connection between the two is digital balanced, and the two are available to be bought separately; however the KW Trans can only be used with the KW Dac. The Dac sports bouble single-ended output, one valve one solid state. To my ears is treble in particular is very defined and analogue-like, and fatigue is non-existant.
Better sounding CDP's may be around but ultimately I haven't heard any better as jet.
Not a cheap option at £4000 (I live in scotland).
I recently listened to the Copland CDA 823 (at exactly half the price of the KW), a nice little player that altough it hasn't got the kind of resolution of the MF KW it shared the same un-digital and free sound.
Indeed worth a look with budget in mind.
Another exellent player is the Meridian G08, very nice but musically leaves me a bit detached.
Hope this can help
