Moving away from inefficient/low impedance speaker in order to move to a Tube Amp

While I am impressed with the Klipsch Heritage line of speakers driven by tube amps... I'm equally impressed by the Harbeth line of speakers driven by the type of amps their designer (Alan Shaw) suggests drive them best - high powered SS amps, which best control their drivers (Hegel in particular)!  

I drive my Harbeths with the Hegel H590, but the other Hegel amps drive them equally well (H390 in particular)... and... they seem to be driven very well by the McIntosh MA252 or MA352 (tube/ss hybrids)!

If... you... don't want to totally disrupt your system.

I'm driving my Forte IV with 40 watts of EL34 power in a smallish to medium room and its plenty of power .   It was plenty of power for my Revel M106 too as long as you didn't want to crank it too loud.  Not the best pairing but sounded great at normal to moderately loud levels 

I am having a 300b built and 8 watts should be plenty for my system and listening habits 

Folks seem to forget one very important factor when choosing an amp, tube or ss, and that is the quality and ability of the transformer. This, IMO, has more to do with the drive capability than just about anything else. The amount of watts/ch is secondary to this aspect. This is the reason that a lot of well built lower powered tube amps with great transformers can sound as loud, or louder, than a much higher output ss device with a wimpy transformer, as an example.

i suppose IF ya think of mechanical amplifiers aka compression driver / horn and cone breakup as not lossy, a bit of uniform compression ain't the devil you think it is…

For those seeking stunningly well designed and executed output transformers look no further than Gow’s MC240 or Roger Modjeski RM-9. 40 wpc and 100+ WPC….

BTW, heard an absolutely gorgeous sounding pair of Harbeth w Line Magnetic low powered amp the other day at Gig Harbor Audio….

Cast a wide net ;-)

+++ @daveyf right you are, BOTH ( or more ) transformers…power supply , output…and ?
