anyone else daisy chain "jitterboxes"?

After using a Monarchy Super DIP for the past 2 years, I ran across a good deal on another DIP. Hooked it in line after the Super DIP (so I could use the balanced out into my D/A), let it warm up and WOW! Everything the DIP did on its own was again improved with the addition of the second unit. After listening for an hour, I picked a disc and set out to remove and reinsert them into the chain to make sure I wasn't fooling myslef. Easily noticed as they were added and removed. The biggest change was in the amount of space around the instruments and vocalist. Everything opened up. I remember reading a "buzz" sheet that Monarchy packed with my first DIP. The reviewer experimented with daisy chaining and found 1 was good, 2 were great, 3 was a slight slight improvement and the addition of a fourth was not noticable. I held this in the back of my mind and am glad I gave it a try. For a total of $350 including cable, I got a significant improvement in my sound.

Interested in other success or failure stories along this line.

Assoc equip.: Theta Basic -> Super DIP -> DIP -> Monarchy 18B or MSB Link III into passive control -> Krell KSA80B -> Sonus Faber Concertos. Transparent Super cable throughout.
