Zu Defintion 1.5 vs Def IV

Houston we have lift off!
Def 4s it is. I'd still love to hear about what I'm going to hear...

Beautifully written, as usual....I can do the $$ so it's a no brainer. The Radian 850 tweeter sounds very exciting.

Thanks Mark. No Radian on the Def3s is the deal breaker for me. The high end was always a bit of a problem for me with my Def1.5s and listening to all the Zu people who have heard both, including you, makes this a no brainer. Now all I have to do is pack and ship my 1.5s (ouch) and wait. My SET is good for 32wpc clean. Ear bleed levels for me. Speaking of ear bleed levels, year ago I had a friend bring over his Bryston 4B to hook up to my rig to hear what these babies could do. Never got close to red lining the Bryston. My pictures were moving. Devastating, ear shattering, killer sound. My Bel Canto does it when I need the hair on the back of my neck to stand. Most of my listening is oh so sweet.

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?

My 1.5s are red matte. Not Ferrari red, rather Mercedes "Mars" red. My 4s are natural maple. Light and beachy like our home. My (5years ago) 1.5s came on a pallet because Zus packaging was the pits. I could never send my 1.5s back in them unless they were strapped to a pallet. That's why (doing it backwards, but less expensive) I'll send my 1.5s back in the same box of my 4s. Sean says they will fit like a glove and not to worry. Christian says I should be seeing these babies around mid February...sweet

Fedex it be. Gsm your system appears to be in a crib (very live listening area) similar to mine, in that I too have very high (12’) ceilings and my speakers will be resting on the floor with an area rug inches away. I’m imagining the down firing woofer. Must be nice.

That is quite a space you got there. What AD issue was your crib in? I'd like to check it out. I've been AD for 20 years. Also, when you're in the sweet seat, (I don't know what your listening pleasure is, but since you're a tube guy?) how does jazz,classical etc. sound?

So, as I read you, when you you're in the sweet spot,your rig delivers intimate, revealing and sweet sound in that huge volume of air you got there? I'm thinking jazz plus Ella, Sarah, Anita and the like?

veddy good. I can't wait. Knowing Zu this may be a very long while. What did F Scott Peck say?--"delay your gratification....
