you don't have any issue on the single end? for sure?
you go check it, first.
It has nothing to do with the cable
Feels the same as on my A90. My A90 didn't have any slip or squishiness either. The person I sold it to was also surprised with the quality of the volume knob.How does the volume button feel?
Like on the predecessor?
Including slip?
Just checked mine and no issue with the SE out. Took it up to about 85 volume on low.

That's right. The issue of SE OUT does not occur in low gain.
After changing to high gain, try to connect the cable to the SE OUT terminal and disconnect it.
Then you'll know about this problem.
Every single function counts. Using SE out in high gain is no exception.
thank god i got golden sample then ... i have problems with D90LE tho... so i really understand your frustration with topping guysYep, high gain does it. Causes static in the left channel and the amp to change to low gain.
Many users, including myself, have the same problem since the 2.4 firmware was uploaded. In 2.3 it turned into a low gain with pop noise. At 2.4, the power is turned off.Just updated my firmware to V2.4 ( link ). I don't notice any changes, but at least the restarting issue on the 6.35mm unbalanced ports is still fixed, meaning it now shows -5 for a short time, then keeps working.
l50 or a90 does not turn off when unplugged the high gain. This is an obvious design error.It's only a problem if you use the 1/4" jack on high gain and disconnect the headphone cable while the amp is on. Then it produces some noise in the left channel for like 1/4 of a second and occasionally throws a "-2" error, causing you to need to toggle the power off and on.
So it's not an issue unless you do that specific thing.
Check if your SMSL DAC is in fixed volume preamp mode ( for my SMSL D-6, this is Pr1)I'm new to this forum so, Hi everyone!
I have just received my A90D and started to listen to it a couple of hours ago.
And found it to have a very low volume compared to my previous SMSL SH-9.
It is something like, 60% of the volume, to the point I had to enable the High Gain and put it on the MAX setting.
This setup goes like this: DAC is the SMSL DO200, XLRs Balanced connections, Sennheiser HD800 (XLR)
Yes the volume increases when changing from LOW to HIGH gain settings.
No the Volume Limiter isn't turned on.
Voltage Here is around 120V (kinda high at this time of the day (20:00h)
When playing high resolution content (above 44-16) things are considerably "worse", Jazz @176-24 I have to go to a very quiet room to listen.
Comparing the DO200 Paired with the SH-9 I can never go above 80-85 on volume even using LOW Gain.
But changing the SH-9 to the A90D I had to switch to HIGH GAIN and MAX Volume to reach what is something like 60 on the SH-9 with LOW Gain.
Thing is, I am considering a return of this unit, because it is of no use as is.
Just sharing my XP with it.

Hmm could this be an impedance mismatch phenomena ie the ratio of output impedance of the DAC to input impedance of the AMP is not >1:8 ? Do you use rca or xlr for the connection of the do200 and a90d ?I'm new to this forum so, Hi everyone!

Thanks, It is in Fixed volume, but I have tried the variable option with no avail.Check if your SMSL DAC is in fixed volume preamp mode ( for my SMSL D-6, this is Pr1)
The impedance is a good bet, I can see on the DO200 the output impedance is 100_Ohm and 4V (XLR), and the A90D Input sensitivity is 3Vrms (Gain=High, XLR), the SH-9 don't have the input specifications besides a 47_Ohm impedance.Hmm could this be an impedance mismatch phenomena ie the ratio of output impedance of the DAC to input impedance of the AMP is not >1:8 ? Do you use rca or xlr for the connection of the do200 and a90d ?
100 ohm is quite low...if A90D input impedance is more than 1K...this should meet the 1:8 ratio so perhaps it is not a mismatch of impedance. Anyway, A90 input impedance is found here, and it is stated for balanced, it is 2K and 10K for unbalanced. If this is the same too for A90d, then there shouldn't be an issue of impedance mismatching.Thanks, It is in Fixed volume, but I have tried the variable option with no avail.

try another DAC in combination with A90D and, if volume problem remains, return it.Thanks, It is in Fixed volume, but I have tried the variable option with no avail.
