OP
I was asked this same question a few months back and my typical answer was PASS.
But the owner chose a different path. he got a AGD amp and was extremely happy. he even went as far as doing a dual mono setup.
His Pre is the LTA Microzotl and it works great with the AGD. I believed the model he got was audion. I personally heard the AGD audion in a show last year and I was impressed as it was driving some speakers with large 15 drivers and Ribbon tweeters. i was impressed and how clear the highs and the lower registers were controlled and deep. the AGD can have a good control over large speakers.
Yet it just weights around 10lbs. which is what you are searching for
TRY to audition one before dismissing this option
Good luck
