Great post Julio,
The headphones you have been listening to are seriious pieces of kit on their own. Great that the company lets you audition to compare in your own time and space.
About 6 months ago I was looking for a dedicated headphone amp and purchased one of these off ebay:
With multiple sources I have set up my CD player, VS2480 and a blu ray player (for Robert Rich's Perpetual and Somnium set).
The sound through my speakers improved so much I have hardly used my headphones since then and usually choose to turn on the CD player rather than the VS 2480 when I have spare time.
It's a long time since I've been so excited by music that it's hard to play a complete album. Often what I'm listening to will remind me of something else and I'll have to put that on asap....
I'm hoping at some point soon to settle a bit and start recording again....
