I'm looking at the A90 Discrete, L70 or the Pre90 as a preamp.
Currently have Mac Air (Source and EQ) ->
RME ADI2 DAC FS -> Amps (XLR) -> Salon2
|-> Subwoofers (RCA)
Just on the feature set, I would prefer the L70 or A90 Discrete due to the 12v trigger, Gnd lift, and Display. Remote seems to be a little less finicky on these 2 vs. the Pre90.
Based on ASR and Google/Reddit, there seems to be a number of failures on the A90 Discrete. Even more concerning, are the multiple instances of damage to headphones from A90 Discrete. Fact or fiction?
I have not come across damages to equipment from L70 but have seen an instance or two of equipment failures.
So far no reports I have found of damage to equipment on the Pre90 and no mention of equipment failure. Does the lack of a high power headphone amp increase the reliability of the Pre90? Wish it had a better display and had a 12V trigger.
Can people chime in on reliability and/or instances of damage to equipment on the A90 Discrete or L70 or Pre90?
Can someone comment on cost cutting efforts on the L70 vs. A90 Discrete? Any negative impact on performance?
Thank you in advance.
