I tried one several years ago. Beautiful looking bit of kit I must agree. Surprisingly large though.

Same sort of sound as my PV-10 was, very smooth. Would have been tempted on looks alone but sonically didn't seem worth the extra.

It does indeed have a standard lithium battery in it. Must confess can't exactly remember what it's function is though

Both absolutley trounced in my system by the MF Passive though.
