It's an AMP not a DAC.

Mine stopped working at 1 year and 6 months. White light turns on but no audio at all. DAC is fine, cables are fine. Cheap Chinese junk.

You are paying for a fraction of the price, and complaining about it's cheap junk. Pathetic mentality. I reckon it's not the product been cheap, it's more you been cheap. lol

Either way DROP doesn't stand behind its products and they lost a customer for good.

Is it just mine or does the Drop + 789 pick up cell phone interference?

So I was just thinking maybe you could do an experiment. Power everything up as you'd normally would but remove the rca's from the amp. Call your cellphone and see if you can replicate the issue at various distances. Repeat with the rca's connected. You'll have your answer if it's the cables acting as antennas or if it's the amps shielding. I take no responsibility if something goes horribly wrong :D.

I already did. Cables have no influence, it's the amp.

Just bought this with my 6XX Sennheiser. But I was planning on using the "high quality DAC" thats in my spanking new macbook pro m1-max. Which is 1/8th inch of course headphone jack. Please don't attack me with flaming pitchforks. Anyway, what adapter do I need, or was this just an epic fail? lol (hiding in a bush awaiting response). Fortunately I do also have my UA Apollo Quad with balanced outputs - and this really will just be used for mixing my music (analog synth and orchestral)...

I think you just need a TRS (1/8") to RCA cable.

Save up your $$ and get something else, like a Schiit Magnius or Jotunheim 2...

I own the THX 789 for a long while now. I noticed when I turn the knob there's this huge static noise then it stops when I stop turning. Is this RMA'able? or what is this? I tried unplugging the behind to test it, but it's not the RCA red white cables..

My guess is no but maybe?? I'm pretty sure you're 100% correct that it's static electricity within the volume knob. The internal lubrication is wearing out. I think I've read others using silicone spray lub (fact check me on that). Skim read other posts below yours. My current amp did that brand new >.>. edit 2: Another post I saw this is an inherent issue with ALL potentiometers and will happen with basically any pot that passes audio on any piece of professional or consumer audio gear. with the amp off; you should do a few slow, full turns back and forth. this will help spread the lubrication inside the potentiometer. ideally, do this every few months or so and it will help keep your pots better lubricated. i just do it before use and it fixes the problem edit: I did a ctrl + f search for static and saw this in Feb 2021: Back to the scratchy pot issue, I fixed such an issue on my THX AAA 789 by performing the following steps: turn off the amp, unscrew the back plate (torx size 10 screws IIRC), unscrew the bottom screw, push out (not pull out) the pcb, and liberally apply liquid deoxit (not the spray kind) on the exposed shaft of the volume pot while turning the volume knob back and forth to really work the deoxit in there. One should avoid touching the circuitry or any exposed capacitor leads. My 789 developed the scratchy pot syndrome after 1 year in and the volume pot has been silent and smooth over the past nine months since performing the above steps. No need to purchase another amp when a $9 squeeze tube of liquid deoxit from Amazon may fix the issue (I purchased the $20 vial that had a fan applicator for easier control and application of the stuff). NB: I am not responsible for any injuries and damage that the above steps may cause. The steps are purely illustrative from my experience. Your result may vary from mine. Proceed at your own risk.
