Fedex and Ups Damage thread
The only way they pay insurance claims is if you use their packing service to ship. I had a preamp shipped FEDEX signature on delivery required. FedEx listed drop-off times 5 x before it actually arrived and it had slight damage. The seller had a ... 
Speakers: Anything really new under the sun?
Shearer designs were the 1st time and phase matching designs they also featured pattern control. The W bin many of the early Shearer designs used is still current in pro audio and in theaters. Shearer horns have a near realistic sound quality I ha... 
Gato speakers
All small speakers sound small if that's OK with you then they appear to be a well-made small speakers. Doubt they are that much different than all the other small boxes that are sold today so I would suggest demoing a few doz in that 2k price ran... 
Does measurements really matter?
A speaker needs to sound good that's what home loudspeakers are designed to do but to do so you need basic measurements all transducers and electrical parts used in loudspeakers are carefully designed and measured. So if the designer voices by ear... 
Dynaudio customer service ignoring me
You can find a woofer from another company that would do the same work. Less of a difference in similar quality transducers than you think.

American Made Audio Products
While with some designs it’s hard to get all American-made inc fasteners etc. But on a few loudspeakers, I build every year I use 80% American no Chinese parts. All my cabinetry is hand-made in the WI USA with American materials glues and fastener...

The panic selling of tube audio had begun.

Law of Accelerated Returns
There's is the better performing and there is the most costly in my findings much of high end is just adding zeros to prices to attract the wealthy into considering them worthy. YMMV  
Speaker positioning: why do audiophiles neglect this so much?
What about dipoles? They have a figure 8 radiation pattern the back wave being out of phase with the front they require to be pulled out into the room but between the loudspeakers, there is a null thus it will not be a problem to put gear between ... 
Speaker positioning: why do audiophiles neglect this so much?
Audiophiles don't understand radiation patterns for if they did they would understand that only loudspeakers that don't have controlled directivity require no items to be placed around them. Where as those that do have radiation pattern control an...
