Speakers that are good with tubes

@hilde45 

To be clear, I agree with you on the importance of capable high quality output transformers. Equally important is the amplifier power supply robustness and quality. The OP is a bit vague and general. I believe posters are just trying to abide and explain what parameters determine speaker “friendly to tube amplifiers “.

Not sure what amp you have, but if it is a good quality amp and you want to hear the music as it was recorded, Magneplaners are the only choice.

If you don't really care about that, pretty much any quality box will do.

Cheers!

@carlsbad I have some buddies here in Denver area with that low-watt, high efficiency approach. It’s pretty magical, and I’m tempted, myself. But that’s a much more difficult path for me at the moment, as it would require getting rid of all my amps and speakers and starting over. I’m moving incrementally, and am currently pretty happy with my non-SET amps (Mono 60’s are great with the KT77s, and the Pass XA25 is really nice, too).

@charles1dad Agreed. Sometimes these threads are like rivers which develop tributaries. Perhaps that’s where I floated!

@richopp Would you say Magneplanars are the only choice -- above and beyond GR Research, Spatial, and others of a similar ilk? Curious as to how you arrived at this very exclusive conclusion.

@richopp We got it. You're a magnaplaner man, through and through.  But I will mention that I was pursuing an electrostatic speaker system when I fell down the tube rabbit hole.  My second system is still Martin Logan CLS.  It wasn't until I found tubes that I was able to exceed the clarity and definition that the electrostatic speaker gives you.  Not bashing your speakers but pointing out that there are other options.  BTW, this is not a magnaplaner thread.

@charles1dad - by the way I love your user name!

So who’s doing this ? People have rightly posted that speaker impedance and phase angle characteristics are factors that require awareness and consideration. This is true as they greatly influence how successfully a tube amplifier will pair with them.

If you rad through the responses, you can see what I am saying.  I do not want to call anyone out so I left my comment as such.

As far as impedance and phase angle, maybe matching a95-99db speaker has benefits but overall unless you are using 100-200wpc tube amp on one of these speakers, a good designed tube amp will do what it takes.  But I am taking class A designed tube amps.  We have a few AB designed tube amps from well know manufacturers in our Listening Room and that is what most people have experience with.  Out 40wpc mono blocks drove the YG Acoustic Carmel speakers with ease and outperformed the $16K Class D amps no contest.

Happy Listening.
