Will you be paying by credit card, cash, or check? After carefully weighing all the options, pay with the one that weighs the least. That will get you the absolute most, pound for pound, of anything.
What does amplifiers weight has to do with performance?
  • Larger transformers weigh more
  • Larger capacitors (and/or more of them) weigh more
  • Thicker chassis material weighs more
Otherwise, not too much.  A thick face plate and heavy footers weigh more but those may or may not have an effect on performance.  However, there are many other factors that may affect performance but not weight, including the circuit design.
