You're welsome! The headphone output is certainly good enough for most headphones, it sounded great with my Westone 4s, but didn't have enough grunt for the HE-500, though it sounded very similarly to the Lehmann BCL (perhaps slightly less bright and energetic) and much better than the Essence STX. The NAD seems to be a good step up and give a lot of high end DACs a good run for the money so I'm quite excited about getting one eventually. The digital preamp sounds like a very good implementation as well.
