Integrated tube amp for 91db open baffle speakers

My vote is for the Cary SLI-80 but you must get the Signature version. What an amp for the money. I had to sell mine cuz my 2 year old son burned his finger the other day. I have not heard the other 3 you had mentioned.

Add the Rogue Audio Tempest II Magnum and the Cronus Magnum to your list.Both are simply outstanding units.Try to audition them if at all possible.

i think the Audio Note Soro SE (18 robust wpc) is the best deal I ever got in audio at around $1500.00

Another good buy is the Manley Stingray which is even more robust
