ok, thanks . i just ordered the HD650 's
Good choice of 'phones. I have a pair of HD600s and they scale up well with better equipment and should you ever get the urge I'd imagine the 650s will too.
The initial impressions I've seen of the Vali is that it's a very good amp for the 600/650 so would be a relatively inexpensive upgrade if you decide you want to dip your toes into tube waters.
The other advantage of the Vali is that the tubes are soldered in so doesn't support tube rolling. Whilst it's great to try different tubes it can be quite an addictive and expensive path to go down
thanks for the details on the headphone amps+dacs
Yeah sounds a bit weird I guess but I really do need a externally 2nd source and only listen via headphones most of the time.
I am quite impressed with the reviews on the EHP amp+dac

Guy mentioned he has never quite heard sound so clean and detailed before, even better then his Asus xonar card in sq and even in BF3 he can hear footsteps and detail much clearer.
£189.99 also I see so not bad for something that could last a long time!
I have the standalone Epiphany dac and amp and like it a lot. I did read that review before buying but I took it with a pinch of salt. Do I think it is a 10/10 combination and has it made my jaw drop? No.
For the money it is about as good a combo as you can buy for the £200 mark though and I found it a decent upgrade coming from an STX. The dac is excellent and for gaming, movies and tv the amp works well. Whilst I can appreciate its sound qualities I find it a bit too neutral for my liking but I do tend to prefer a tube sound, so that's just a personal thing. It is a revealing amp and whilst that can be a good thing is also shows just how bad some recordings are!!
If you are totally against the idea of an internal soundcard then a wildcard option might be the Xonar U7.
The U7 is an external USB soundcard with a built-in headphone amp. I've been playing around with one over the last few days and for the £70ish price it's available for there is a lot to like but the odd weakness too:
Good:
- an Astro Mixamp like desktop box allowing easy control of audio volume & a mic input with its own volume rocker
- good connectivity with a line in, rca outputs (to powered speakers or AV system) and spdif optical out
-many of the benefits that a good internal soundcard offer e.g. 7.1 support, virtual surround and a software suite with the usual EQ adjustments etc.
- dac seems pretty good
- usb powered so no power brick needed
- available for around £70 through a large online retailer (don't think OCUK stock it)
Not so good:
- an internal soundcard like the Xonar DX is cheaper and has a slightly better dac
- the headphone amp is decidely average. More like the one on the budget Xonar DG/DX rather than the STX
As I say the amp is no great shakes but would be capable of running the AKG 550s as they don't need a lot of amping (but like many headphones will sound better with a good amp).
I did hook the U7 up to my Epiphany O2 to see how it compared with the built-in amp and it was a fairly huge step-up in terms of audio quality, which suggests that the amp really is the unit's achilles heel. Playing COD Ghosts with the O2 + U7 combo with the Dolby Home Theater feature enabled is as good a surround sound experience as I've had with headphones on.
For the money I think it's hard to fault the U7 though. Shame about the amp but that's perhaps a combination of Asus wanting to keep costs down and the limitations of usb power.
