Unfortunately most do not understand what they "hear", so most discussions are not worth the time.
Most want to believe in something, in something modern, in something expensive, to a "Guide" or whatever. But it is so simple, go out, buy those units, compare them with records before Reissues became a "Standard".
I have those Arms and I did. Others too. It is is normal, some will never get it. NEVER. Not in this life, nor the next. That is normal.
When you don't hear the difference, fine, when you hear a difference, fine, too.
When you need to spend a lot of money, because you feel better that you can afford something the other one can't, fine too. Most do that. That's for most a kind of satisfaction, for showing others "look, I am the greatest music LOVER..."this is the normal business.
It is not necessary to change the world, but sometimes - not always - it can be interesting to go a different route, Hardware is for most a kind of Altar, a secret, a Holy Grail...they pray to it, they want it to look nice, expensive, important etc.
But when this is over and the needle touches the groove...then a new chapter starts....:-)
