I just traded up on my 5Ts and 5Cs. Aperion handled all of it, determining the costs, sending me the return labels, etc. I simply have to attach the return labels to the outgoing 5Ts/5C and FedEx will take pick them up when the delivery my new toys.
The 6Ts/6Cs are monsters, so I expected the shipping to be a bit pricey. For me it wasn't that bad. Considering I've thoroughly enjoyed my 5 series speakers for almost a year and am now getting brand new speaks a year later, it is well worth the money.
Chat with an Aperion guru, they'll let you know the shipping costs, see if it works for you.
Aperion, you have one year to make a 7 series speaker. Get friggin' busy.
