-If you ordered today, you wil certainly receive an L30 unit that has passed the 'troublesome' serial# range. It will have fixes, no worries.
-L30+E30 will certainly be cleaner output than your average Realteak headphone out
Thank you for your reply, the seller said the E30 will be in stock in March. Asked if I want to wait, do you think I should wait or go to other trusted products, despite reported issues, the E30 and L30 can be trusted.
