Sounds like a great audition list. All amps listed are well respected. I own a CJ Premier 11a and it has been an extremely enjoyable purchase. It has also been rock solid reliable and trouble-free. My last re-tube was a few years ago for real close to $200. This was for higher quality NOS from Kevin Deal at Upscale Audio (excellent to deal with-no pun intended). The cost of re-tubing for the quality of sound is money well spent IMHO. The CJ is driving a difficult load as I use electrostatic speakers and I listen for hours and hours with no listening fatigue. I suspect every amp on your list will make beautiful music. If you want more of the who, what, where, and why of the CJ amp feel free to email me.
Good luck and happy listening.
