I am using all the digital inputs of the Wandla. The USB C is connected directly to the computer. All the other digital inputs of the Wandla (Optical, Coaxial, AES, I2S) are connected to the Matrix X-SPDIF 2. All the digital inputs sound the same to me. Sadly my hearing isn't what it use to...

Thanks Simon. That's good to know. I bought a Ferrum Wandla DAC to complete the Ferrum stack. Haven't used it yet. I'm holding off until my birthday on Thursday.

I'm getting ready to sell my ADI-2 DAC FS. I'm on a Mac and the buyer is on a PC. Do I need to put the DAC in factory settings? I'm concerned that the updated firmware that I installed on my Mac will mess up the buyer's PC. Thanks in advance.

I'll have to give that a try. Thanks for the suggestion.

Thanks for the reply! I mainly have been using the Gustard X26 Pro and recently started using the iFi Pro iDSD with the Oor. I'm guessing the Wandla probably sounds about the same as the Gustard X26 Pro in terms of treble, overall brightness, micro details being its a delta sigma DAC. It's...

So for a treble head like me the Wandla probably wouldn't work out? I like good bass too but I can't stand it when the treble sounds veiled.

I think they are supposed to ship this week (last week of April).

Balance and RCA cables sound the same on both A90 and 789 except the volume output is louder when using the Balance cables. For the input I use usb. I have the Sony MDR-7506 headphones. I guess they would be considered low end. The MDR 7506 sound pretty good with the A90. I'm surprised how...

I used the Topping D90 MQA DAC as the source for both the A90 and the 789 interchanging Balanced and RCA cables between both amps. The headphones I primarily listen to are the Focal Clears and the Sennheiser HD 660S. I don't use EQ presets. When listening with headphones I think the A90 has a...

I’m surprised some people are claiming the 789 has a wider soundstage than the A90. To me it’s the opposite, A90 has a wider soundstage. The A90 has more warmth (bass) the midrange sounds smoother while the 789 is slightly more analytical. When the music gets very busy the A90 sounds slightly...

When I mentioned brighter in the last paragraph I was referring to the treble. I thought the treble sounded like it was slightly rolled off the first time I listened to the A90. After numerous listening sessions I realize that is not the case.

I don't think the A90 is an upgrade for the Focal Clear unless you prefer a wider soundstage and an overall warmer presentation. The A90 sounds a little more engaging, more musical, a little more forgiving to poorly recorded music. Overall there doesn't seem to be much of a difference between...

I’m not experiencing any noise from the RCA either. Given the technical specs I thought the A90 would sound almost identical to the THX 789. Based on a very limited amount of time comparing the A90 and the THX 789, the A90 appears to have a wider soundstage and a slightly warmer sound. At...

^ Those are the reasons why I returned my Sonica.
