sajunky said:ASR "established experts" didn't pickup design fault in Topping A90. Also ASR measurements didn't show ground loops introduced by such a fault. It is despite of the fact that ground loops are typically a plaque of Amir's equipment [only when testing non-Topping products like TotalDAC]. I bought Topping D30 [featuring the best measurements on ASR] and it produce trash, not a sound.
From my experience ASR measurements are cannot be trusted. Having said the above, L30 doesn't look bad and is worth trying. It doesn't have dual MeanWell SMPS outputs hoocked in series [so is free of A90 fault] and it doesn't cost $500. .LOL.
I expected a price closer to $100, it is a real value of L30.Click to expand...
The E30 is $129 without wall adapter, so $139 is reasonable for a sister product.
There are plenty of designs and commercial products in service which use SMPS in series. You have already received replies in all the forums to this.
