Iv had a few dacs one of the best all rounders was a Tag dac20 these can be had for £200-£300 was a £1200 unit new very flexible lots of inputs 3 coax 3 optical 1 XLR so you can plug all your kit into it it usefully has 2 pairs of stereo outs so you can decide what leads sound best.
Other than that Stello do some nice kit Iv had a DP200 dac/preamp which was very nice but not as good as the AVP2's dacs though thats something else in terms of the way it conveys music theres not necessarily that much more detail but it's the way it's placed on a sonic platter like a huge open window hard to explain really you know when you hear
I used to like MF kit then realized they dont sound much better even if you spend more money a guy I know of has had older shape & newer stuff they constantly make new models too quickly too a sign to me of new case higher price but more or less same old kit ?
I had a Xray V3 against a clock modded Teac T1 transport remember it's several years older too both though my dac the Teac wiped the floor with the MF no more bright digital sound just smooth flow thought the whole sound says it all really thats when I started to realize about so called newer tech is not all it's cracked up to be.
When you go upmarket things can get real good you can pick up yesterdays topend kit for a fraction of it's retail but be careful of cable choice you can easily get ripped off,I actually make my own cables (got fed up with hype there too !) I know they sound whey better or good as any out there regardless of price also the plugs used also make huge difference ether Eichmann Bullet's are good but WBT Nextgen are by far the best.
