SET vs Push-Pull (Line Magnetic vs Primaluna)

"I had to go back to the LM 218iA. The main positive of the AR was that it was slightly quieter in the blank spots on phono records. But otherwise, my music just sounded better with the LM: more nuanced, immediate, intimate, real." 

Yep, these are the special attributes of SET amplifiers (Especially "real")  'If one chooses an appropriate speaker pairing.'.  In my opinion it's better that you learned this on your own via direct listening with your system.

@making,
At your typical listening levels of  70-75 db at your listing distance you are not even using 1 watt of power, just fractions of a watt. Your listening levels are very comfortable and satisfying for most anyone not suffering with a hearing deficit. I hope you get the chance to hear the Line Magnetic 805 output tube based amplifiers and compare to your push pull PL amplifier.

No question an audition is the ideal scenario if it can be arranged.  As I wrote earlier the demonstration rooms at the Venetian Hotel were pretty good size and with probably 10 or 11 foot ceiling height.  The 50 watt PSET amplifiers -Crescendo speaker  filled the space with beautiful sound. So certainly a viable possibility.

"Too many times I have heard pairings that should have been made in heaven sound fairly ordinary, and rather unlikely bedfellows sound entrancing."

@pesky_wabbit,  absolutely and unequivocally an astute observation. My experience as well on numerous occasions.

@mabonn,
There is an excellent store called Pitch Perfect Sound located in Palm Desert CA. They have Line  Magnetic, Leben, Shindo etc.

3 years in a row I attended the C.E.S. in Las Vegas. The Acoustic Zen Crescendo each time shared a room with Triode Corporation of Japan.
The Crescendo was paired with the Triode Corporation Parallel SET TRX M845 mono blocks that are 50 watts per channel.

This combination filled the generous sized room in the Venetian Hotel gloriously. Each year this demonstration room was always one of the better sounding rooms at C.E.S. I don’t know your listening room size but the Ventian space was again far from small /cramped.

Line Magnetic 805ia /508ia (805 output tube) class A SET is 48 watts per channel and could be a serious candidate based on what I heard with the 50 watt Triode Corp TRX M845. The sound was big/spacious, beautiful and very natural and nuanced.
As ozzy62 stated above, Line Magnetic is very good quality.
