SET vs Push-Pull (Line Magnetic vs Primaluna)


I have a Primaluna Dialogue Premium (non-HP) driving my Acoustic Zen Crescendo II loudspeakers.  It's a push-pull Class AB design.  
I am intrigued by the possibility of trying a Class A SET design.
Has anybody tried a Line Magnetic Class A SET amplifier with these speakers?
If so, what are your impressions?
Where can Line Magnetic amps be demoed or bought in Southern California (San Diego area)?
Thanks for your responses.

I find theorising about about amp-speaker pairings to be a fairly futile excercise. Too many times I have heard pairings that should have been made in heaven sound fairly ordinary, and rather unlikely bedfellows sound entrancing.

There‘s only one way to find out….

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

Melody is now located in the UK. Doesnt have any North American Distributor/Dealers according to their website so do they even have USA 120 Voltage option? Prices are DOUBLE in some cases vs LM amp with same tubes.  They list a link to reviews of several of their amps on their website AND the reviews for the 34, 2A3 and 211 amps pretty much say they cant Rock and bass is deficient. Wonder which amps KeithR is referring to above.

Science can often give you a good idea of what to expect but there's a lot to be said for the empirical method.


In the case of the OP, the room is the big variable. If its a smaller room a 50 watt SET might work, although it will be unable to show off the bandwidth of the speakers (where a 7 watt unit could...).  If a bigger room with nice carpets and the like the SET will be pushed past its 20-25% rule of thumb limit and/or may well just fall right flat on its face.


(In order to find out a fair bit of $$$$ might have to flushed down the loo; if you can arrange for an audition prior to purchase!)


Many people push SETs past this 20% rule; that is where the idea that SETs have such great dynamics comes from; the 'dynamics' is actually distortion although the amplifier isn't being overloaded.
