You guys have me scratching my head. Two Crack kits with Speedball upgrades to make a differential amp would cost nearly as much as a Mainline, which is an even better sounding amp and has a balanced output option. True balanced, not differential - they are two different things.

I think at this point we are having more fun at entertaining the thought of it lol. Thanks for pointing that out though Doc :)

I know balanced technically refers to matching impedances on the signal lines.

 

Is a differential amp inherently balanced?

I like the explanation of differences between the two in this article

EDIT: They also have some pretty neat audio transformers and misc. gear too in their store.

No. Differential amps can be balanced or unbalanced. However balance is required if you want to achieve maximum common mode noise rejection. There is a lot of confusion because the first "balanced" headphone amps were never promoted on the basis of common mode rejection. They were just two amplifier channels bridged together which while technically "balanced" we're not differential so any notion of common mode rejection was moot anyway. But the term "balanced" was used anyway and that's how we ended up where we are. Some amps are balanced in the traditional sense (balanced with differential inputs) but most are what should more appropriately be called "bridged."

Gotta give credit to brunk who gave me that beautiful set up. Thanks, brunk! biggrin.gif

Ok, enough of this silliness. Back to drugs, sex and more drugs.

Hey doc if the Mainline is truely balanced than why doesn't it have balanced inputs?
