@shooter69 - well, funny you should mention that!
I finally picked it up yesterday. I'd bought it off Ebay last Wednesday, phoned the seller (Audio Elevation in Doncaster - highly recommended, Ian's a decent bloke and do check out their site) the next day to have it sent to my work address, but, as it's a fairly big company, the Royal Mail batch everything up that's going there and it finally arrived yesterday (Monday).
Thanks to being out with a mate last night, I only got it up and running today. It's a neat little unit, and nicely built. Not battleship standard, but robust enough for normal use. I've had it running about four hours now and cutting to the chase, it leaves the DACMagic standing.
There's a nice depth to the bass, full midrange and the treble's there without being in yer face. Currently running one of my test discs (Genesis' "A Trick of the Tail" mastered by Barry Diament) and it's so close to the CDP it's untrue. Yes, it's really that good. Freeview radio also benefitted immesely. Compared to the SA7001-KI, it's a little hemmed-in soundwise, but really, this is a minor quibble. What you get is a spacious, rhythmic and wide open sound that lets the music live in a way the DACMagic toiled to achieve. The DM wins out over connectivity, but the sound is what counts.
The Spitfire II takes three inputs - one each from USB, coax and optical connections. There's no selector, nor does it tell you the incoming or outbound rates, but I can live without that - no biggie.
Given its diminutive size, this'll fit nicely just about anywhere, but one little thing to consider is the brightness of the lights on the fascia - the blue power and green lights are pretty bright and I found also reflect off the surface off the TV stand. Long and the short of it is it might be better to position the unit sideways on and/or away from your line of sight to avoid distraction. Again, minor issues.
For £250, this is a good piece of kit, well built, with great sound and I'm happy to recommend it readily, even after this short time. I bought mine, as I mentioned before, for £150 and thanks to a discount which I think will run out soon, it's a steal. Anyone looking for a cheap, effective and high performance solution, particularly where funds or space might be limited (or both!) should shortlist this little DAC for audition at the drop of a hat. To my way of thinking, this is the giant killing budget DAC on the market right now; a Goliath in David's clothing if you will.
