Quality control, attention to detail, proper design, better parts, better transformers (big one there), and better customer service and warranty work are all reasons why the higher priced units are worth it. Quality transformers aren't cheap and greatly influence the sound. They are critical IMO to make a great tube amplifier.
It all leads to better security and most importantly, better sound. I normally don't even recommend tube products unless we start talking around the $3,000 mark as I feel that is where all the above start to line up.
