Legacy or prestige series...you will never go back to anything else, lifetime speakers. Oldest speaker manufacturer in the world.

You should check out Scaena before deciding.

Peter Breuninger has been reviewing the world's best audio gear for many decades, and recently he reviewed a $15,000 speaker that he says is a "breakthrough" speaker and the best he's heard.  You can see his review here:  https://www.youtube.com/watch?v=Ma7dvPyr5T0 

I contacted the Chicago dealer today, and he said they offer a 60 day money back guarantee.  

Go to sanders sound website, and speak directly with the designer/owner
 you will pleasantly surprised at how honest, and knowledgeable Roger is.

  He has a 30:day in home trial, if your not satisfied (YOU WILL BE ASTONISHED) send the back.

 He is one of the premier designers/owners/inventors of the Sanders sound speakers and amps.
the Sanders Magtech amp (stereo) or his brute force Monoblocs will satisfy your every need, there is not any speaker the Magtech will succumb to,
a little pricey, but they are truly world class.

invesigate his website and reviews.

 The amps will drive even the most demanding speaker.

 Read the MBL sanders review,
even a Carver sunfire was partially owned by the MBL radiostrhaler monolith speakers.

as soon as I get the scratch, I’m going full Sanders sound audio,
they are that good!
