I don't know anything about these cab companies, but I'm bumping in hopes that someone else knows and will chime in!

yeah it does not seem like many people know about hansemm. I saw some posts for yorktowne and they are rated ok. price-wise I am about the same but with more features on the hansemm. I dont think you can wrong with them if you do the 3/4 ply option instead of the particle board sides. Yorktown uses thinner plywood sidewalls on all of their cabinets and they seem to be more stock sizes and more costly to customize.
