Here’s my take on a bunch of <$200 headphone amps:
The short answer is ‘no’. The A3 is class-leading in its spatial reproduction. One of its standout features at the price point is how well it does soundstaging and imaging. It will actually enhance the 1990’s abilities from what you’ve heard with L30 in that regard. If the A3 is more than you want to spend the Magni 3+ likely does that the next best, at least from your list.
The E30 dac is still a fine product as far as I know. So hang onto that one for now.
