i am using a VSX-D908TX ( 908rds is a european version? ) and so far, OK naman siya for my HT set up.
the VSX-908TX i bought is " made in japan ". i have inspected the rear panel of the the 859 txg displayed on store and the label says " made in indonesia " or is it malaysia?
i have not tried or audition the 859txg but used to have a VSX-D701 ( also made in indonesia ) and boast a higher power output than the 908Tx. in actual use, mahina yung indonesian made pioneer VSX-D701 AVR.
so, i guess, you might get same result.
also, the price may indicate that the 908tx is well crafted since it cost more than the 859txg.
try calling up sonny tuazon. i got my used 908tx unit from him at a very good price.
