Looks like 3rd rail is not offering any dummy B units, right?
RIGHT.
That has a BIG impact on the $$$ of an ABBA lash-up.
Atlas-O pre-order ABBA with 2 powered A's $1,184 from Mr Muffin includes FREE shipping.
The 3rd Rail ABBA is $2,400. My estimate for shipping from 3rd Rail about $40.00.
I am sure that the Sunset 3rd Rail units are excellent both in appearence and performance, but I just can not justify the cost. If you can, more POWER to you.
