Just to pile on a bit, I have the Magneplan 3.6r with dual self-powered subwoofers driven by an NAD M33 which is rated at roughly 380wpc at 4 ohms, and I would consider that the minimum. I'm considering trying a Bi-Amp setup using the companion M23 amp one of these days; I just don't get enough chance to enjoy them since work tends to keep me busy.
Electrostatics and tubes
I am looking to get some new to me speakers, I've been looking at options and would really like to try a set of planars "electrostatics". I have read or heard somewhere that as far as speakers go they tend to be inefficient (85 to 89) vs.90+(db) on the Klipsch or Dali's I've been tossing around as a standard speaker option. I guess my question is would I need to worry about any over heating issues. I plan on using plenty of power with a set of VTA, M-125's to power them. I am looking at a lower budget set maybe Martin Logan ESL 9's or Magnepan 2.7i . Just wondering I would hate to over heat a few hundred dollars worth of tubes if I don't need to. ¯\_(ツ)_/¯ don't roast me to bad I cry easy 
thanks.

Seems like there is a lot of dialog with watts and playing loud. I own Electrostats and Maggie's. All of my amps are Monoblocks pushing out over 700 watts per block. Sometimes I play them loud, but most of that power is for the dynamics, power in reserve for the speed, control and peaks that will make those panels sing. You can play loud with any amp, if you like distortion. The high wattage, high amperage power amps are what's needed to get the most out of your panels at any listening level. |

Your message made my heart beat faster. I also restored a pair of ESLs and Quad IIs during the 70s and still groan at having been forced to sell them at liquidation prices when I was forced to downsize in retirement. FWIW, after spending years pairing the speakers with numerous power amps, I could not find a better match than Quad's own 1950s-vintage Class A Quad II monoblocks. Today, I listen to gear that is an order of magnitude pricier than my old ESL/II combo, but in many ways, the Quads still remain unmatched. Que lastima. Boy, you would have loved the Quad IIs when they returned, all shiny and refurbed, from Quad’s UK factory! Here are the only photos I could find, shot at different times during the restoration process. You can see my 220V Quad IIs to the right of one of my Dynaco projects-in-progress, as I originally purchased them, including NOS Quad-branded tubes.
