If you want a pre-amp, then A90 because A30 Pro is pass-thru. A30 is also more aerodynamic with all of its vents . Both have exceptional power and SINAD.Better A90 or A30 Pro?
Not sure which is better for IEMs.

I use it via 2xlr 2xlr balanced cable to a Matrix mini-I 3 Pro as a dac, only for headsets. I use often low impedance and medium/sensible headsetsIf you want a pre-amp, then A90 because A30 Pro is pass-thru. A30 is also more aerodynamic with all of its vents . Both have exceptional power and SINAD.

I'm confused, what is the "it" you are talking about? The A90?I use it via 2xlr 2xlr balanced cable to a Matrix mini-I 3 Pro as a dac, only for headsets. I use often low impedance and medium/sensible headsets
"it" stands for headset amp A90 or A30 Pro. I have to chooseI'm confused, what is the "it" you are talking about? The A90?
If you don't need the pre-amp function, then IMO A30 Pro because it's cheaper."it" stands for headset amp A90 or A30 Pro. I have to choose
And if I'll find an used in excellent condition A90 at the same price of A30 Pro?If you don't need the pre-amp function, then IMO A30 Pro because it's cheaper.
Then I would be tempted to go A90, because down the road if you want to connect to desktop speakers you can attenuate the volume via the A90 as a pre-amp.And if I'll find an used in excellent condition A90 at the same price of A30 Pro?
It’s what I just ordered. Will let you know my thoughts if you’re willing to wait that long. Although, based on Amor’s reviews of each, it’s a good combo to get if you can afford it.Didn't think of that. Good point. Thanks!
Still considering different combos but the Topping + Gustard looks like it has everything I want.
I'm surely interested in reading about your experiences with these products.It’s what I just ordered. Will let you know my thoughts if you’re willing to wait that long. Although, based on Amor’s reviews of each, it’s a good combo to get if you can afford it.
RMA, sureHas anyone here heard of or experienced intermittently shifting balance in the A90?
I got a second-hand A90 and I don't mind that the thing still plays music with the volume pot turned all the way down, but the balance in this thing is all over the place, constantly shifting to the right slowly and then going back to the middle, only to shift left. At first I thought that maybe it was because the device was cold after the delivery, but after several hours it is still doing it.
Any idea what's causing this and can I fix it by myself or is it a manufacturing issue and I should just RMA the thing?
For my own use I use the variable output of the D90 to allow me to utilize the M and H gain positions. I can set the D90 to Pre mode (hold down SEL button as you power up to get options), then reduce D90 MQA output to -9dB and -15db to use M and L gain settings.Is there any downside to utilizing low gain to drive the HD 800 S?
I've done some testing, and my previous sources were not nearly as efficient, because "low gain" (on the A90) makes the HD 800 S seem like an unbelievably "easy-to-drive" headphone.
I asked about a potential "downside," namely because I've read that "loss of resolution" can occur if not powered appropriately. My desktop setup is the A90 + D70s, and on low gain, approaching noon is pretty darn loud (depending on the genre).
Low and Medium gain both have lowest distortion possible. If you reduce dac volume you lose dynamic range though.Is there any downside to utilizing low gain to drive the HD 800 S?
