Has anyone dealt with High Performance Stereo

I believe their located in Miami Florida. 

I've visited their new location and met the owner, but I ended up not buying from them as I found a deal and a speaker that suited me better.  I spoke to another dealer in the area, an authorized Wilson and ARC dealer, and he knows the owner from  high-performance stereo, has for several years. All this to say, yes, it's a legitimate business, and has a history, but I cannot personally vouch for them, as I never did any business with them.
FWIW I've bought some new Krell gear from them and thought the entire experience was very satisfactory. I recommend them.
