Well you said "anyone else besides spkrs01" so I hope you didn't mistake me for spkrs01 ;-)!!
After reviewing both I bought the TUR-06 but that was because size mattered to me. I think the 05 is probably more neutral and overall leans more towards an audiophile's sound whereas the 06 leans towards a more fun sound mainly due to a slight bass emphasis. I chose fun in the end for myself.
No no, don't worry, I know who you are :-)
