As I recall, the original transformer was $6, so two would be $12 (stereo)
and the additional $8 for this product is well worth the already-cabled and
packaged configuration.   If it really is a 1:1 ratio with appropriate
impedances, I think it is a better deal.

For comparison, the W2IHY iBox is $60 and has RFI bypassing plus a level
control.
