It seems non-audiophiles never tire of proving that everything sounds the same.
Just read another blog about how nobody could tell moster cable from coat hangers. There's just a never ending stream of people that love to prove that:
All amps sound the same.
All dacs sound the same.
All cd players sound the same.
All cable sounds the same.
All electricity sounds the same.
All digital compression sounds the same.
Only speakers sound different. So, you could buy the cheapest electronics available and hook it up with the cheapest cable and it would sound identical to a $20k system as long as the speakers were the same.
