joule electra vs. atma-sphere any input?

I owned a pair of MA-2's MKII. I found the amps, within this specific system, to be articulate, detailed with great bass. The Joules Rites, which I have now, and to iterate within this system, have a bit more body, density with nearly the equal in delineation.
These are two of my favorite amps, especially amongst tubes, with great imaging, staging, frequency extension; and no exaggeration in the midbass through the midrange.
I have had absolutely no mechanical problems with either set of amps.
Some opinions may side towards the Atma Sphere if balanced connections are used. With the A-S preamp, balanced out's offered a more musical, yet detailed presentation. With the preamp I now have, modified Jadis, the Joule in single-ended is just supurb. Some of the best music I have ever gotten out of an audio system.
As usual, individual tastes and component match-ups should be the determining factors.

The Atma-Spheres were MA2 MkII.2. I believe this thread, as many threads, requires a reminder of how critical component matching is. Everything from cabling, isolation, individual pieces of equipment, tubes within those pieces of equipment, and of course, room acoustics.
Every system I have put together has changed by some degree when introducing a new variable. Some for better, some not. This does not preclude the character of any individual piece of equipment. An example can be drawn from the recent upgrade of the tonearm on my table. It has taken the entire presentation in a different direction. One, thankfully, I am most impressed with.
In an attempt to avoid a too didactic stance, let me add that both of these amplifiers, as are others I have owned, great makers of music.
