Zu Defintion 1.5 vs Def IV


very quick electrical surges due to hurricane Sandy blew one of my sub amps. Now, I'm reconsidering the IVs or having Zu replace the blown amp. Is the upgrade to the IVs worth the $$? Any Zu owner that can site specific differences, kudos, etc? Bass as prodigious as earler Defs? The whole nine if you could. If it be easier a call would be very cool. 516-316-3311...Phil, you were responsible for my Def 1.5 purchase. Please give me another shout. thanks in advance.

My experience what works now is a time and fate thing. If my Def 1.5 amp had not blown, audio life would go on 'til something else happened with my rig. My laser is going south on my Exemplar, hence, a new laser or a different more costly John Tucker mod? It's crazy, but I have had this rig for 5 years and have been very satisfied. The thought of going from the 1.5 to the 4 is very exciting. With the trade in it is $$ friendly to the wife. Happy Holidays
Late Channakah gift: Ordered my Def4s today. Zu (love those guys) will give me lead time to send back my Ibis speaker cable to reterminate. When they arrive I plunk my Def 1.5s in the box and back to Zu for my credit. Fedex or UPS? I'm leaning Fedex from experience (from The Hamptons NY), but never shipped anything this big. Suggestions?
I just shipped a $4K Audio Research amp from Ohio to Albany, NY using FedEx. It was delivered during the busiest week of the year Dec 20, 2012. Perfect with no complaints.

I have used them for amps, speakers, stands, and turntable without fail. I always take pictures and buy insurance.

Good Luck and congratulations!!!!
I agree with the FedEx choice Warren. Also the nice custom boxes that Zu sends the Def 4's in are bullet proof for the most part so you should be safe. What color are your 1.5's btw? Maybe someone wants a jump on what will be the next Def 3......
Who to use for shipping is a crap shoot. Freight, strapped to a pallet, would be best if you could swing the $$$. I believe that's how Zu is going to ship your Def 4's. I would make sure to take plenty of photos during packing them up showing them in the custom foam enclosure. FWIW, I sent my Def 3's back to Zu with UPS ground without issues.
By the way, what color did you order your 4's?
