I just got my new A90 hooked up top my D90 and right away noticed buzzing/static noises when I move my mouse and open programs. This is with the usb cable that came with the D90 hooked to my pc which is my source for everything. It didn't happen with the THX AAA 789 and nothing else has changed. Has anyone found the fix yet?

How do you have the D90 connected to the A90? Are you using RCA cables? My understanding is that the noise issues can be avoided if you use the balanced XLR connection instead.

I had the same thing with my Feliks Audio Echo connected to Aune S6 which was connected via USB to my PC. The USB cable was the source of the noise, but it disappeared when both the DAC and the AMP were connected to the same power strip. Try that.

The D90 is connected to the A90 with some 6" schiit audio rca cables. The A90 and D90 are both plugged into the same tripp lite conditioner. If I use balanced xlr between the D90 and A90 will I still have single ended output? My ah-d7000's don't have balanced cables.

this is the line conditioner https://www.amazon.com/Tripp-Lite-LC1800-Conditioner-Outlet/dp/B0000514G8

Yes.

Yes, you can still use single-ended headphones when using the balanced input.

Ok thanks guys. Looks like they don't cost much. https://www.amazon.com/Audio-2000s-...hild=1&keywords=xlr+6"&qid=1612472483&sr=8-37

EDIT: Only heard a few songs so far but as long as the crackling is drowned out by music the amp sounds fantastic. Still in the process of passing judgement but if the xlr cables work out it seems like a keeper. I just can't fathom why they would include rca inputs if they don't work correctly. The thx 789 had no issue with the same setup.

thx 789

it was also fake balanced

 

[Brando]

it was also fake balanced

I guess that's another positive to switching to the A90. I can finally go true balanced if I get my phones cables switched. I feel bad for anyone that gets this and only has rca out but alls well that ends well I guess.

EDIT: got it hooked up with optical until the balanced cables show up. No crackle now, just super clear sound. It's actually pretty insane. I could be imagining it but the A90 seems to have it's own character compared to the thx 789. That shouldn't be possible since they both have specs beyond human hearing supposedly, but I feel like there's something more to it somehow.

I´m on the same boat. I think Jotenheim2 will be. People who got the jot2 now, owned a90 before, sold a90. They say A90 it's like hospital clinical... like singer always sounds few years younger... measures very good, sounds too much... clean... jot2 more class A sound... proper real knob, 100$ less price... 5 years warranty fr the Schiit. If you are in USA, I think it's very clear what's best to get at the moment, no?

I am wondering how the Jot 2 compares to the newer SMSL SP400 amp or the Flux 10.

Switching from rca to xlr interconnects worked like a charm. No more pc noise interference. Just perfect sound. After listening for a couple days my ah-d7000's have never sounded so good. The thx 789 is a great amp but somehow the A90 seems more clear and layered. They also add a little something that these phones needed. A little crispness. Not sure why that is since they should theoretically sound identical but I'm enjoying it a lot. I could be suffering from new toy syndrome but it seems real.

Any recommendations for a DAC to pair up with an A90 for a bit of a warmer sound?

Currently using a Topping D50S connected via RCA. I had my eye on the D90 or possibly the RME ADI 2 for later this year, but just wondering if there are better options available (or slated to be released later this year).

I use Aune s8 with a90, no mqa support but punchy detailed sound into fostex th909.
