So what is the best speaker you have ever owned?

My Lansche No. 5 speakers with their plasma tweeter are by far the best speakers I have ever owned. The tweeter is unbelievably great and incredibly fast. Lansche has somehow managed to fuse their midrange and woofers to the tweeter with little to no difference in performance. It's just a great speaker that makes me want to listen for hours.

Nola Boxer's. The closest thing I've ever heard to live music in a bookshelf speaker.

Shoe,

As a jazz lover the Mirage OMD-28's just make instruments sound more real. I'm not in love with using the descriptive term "musical" since it is so vague, but that's what these speakers are with my gear. They have a good bass foundation and are fairly transparent too. PSB Sychrony were high on my list as a possible purchase, but the price for the Mirage was too attractive.

The best would be my current pair of original Martin Logan CLS (with brand new panels as of this month). Limited sweetspot but once you are in it there is nothing, absolutely nothing (and I've owned 100s of pairs of high end speakers) that can touch it in the magical midrange nor float an image quite as real. It's also a plus they are (in my opinion) the nicest looking speaker ever made.

the New Salk Audio Soundscape 3 way monitor is a thing of beauty to look at as well as hear . The Raal Amorphous core tweeter is the Best tweeter on the planet ,in fact it is not a ribbon in the traditional sence of the word go to Raal s home page, also the Accuton 5" ceramic midrange cone is one of the best out there without question.The 7" custom Aluminum driver has excellent weight and speed
they do need a little power to drive them but an easy load .at 56 lbs and response 42hz-60k one serious monitor and will compete with no problems with anything up to $10k.
p.s I am running a sub from 50hz just for fll into the 20s
This speaker is under $5k if it were sold at a dealer it would have to go for 2x this ,Salk makes suberb speakers at more than fair market cost !!
