I've done a thing and ordered the Hifiman Ananda
I have been reading so many comments about Edition XS and Ananda being the "correct" upgrade from the HD650 and I just can't understand it, so the only way to see is to hear it for myself vs the Sundara and HD650. It's £100 more expensive, but if it's that good as the hype seems to claim, then fair dos. It's from Amazon so I can return no quibbles, or return the Sundara if the Ananda is really that good lol. Edition XS I smacked off the list because that headband looks diabolical and is uncomfy too based on 100% of reviews and the cheap plastic feeling cup housing.
Will be here tomorrow, perfect for the BH weekend of music
Edit* That's the Ananda Nano, not the Stealth version which is older!
