JDS El AMP or Element 2

So I have the L30+E30 stack, and already sent a request to return it. I am wondering if I should refund the whole stack and get the Element 2 or keep the E30, return just the L30 and buy an EL Amp 2.

John at JDS recommends the Element unless you need inputs other than USB. The performance is exactly the same as the El stack.

How would E30+ asgard 3 compare to the element 2?
