I have my outboard USB DAC set up on top of my subwoofer. It's not what I would choose to do if I had other options, but my stereo rack is full, and that's where it ends up.My DAC and the subwoofer are big, stout units. There is no possibility of the DAC vibrating off and falling on the floor. But how do you think the vibrations affect the DAC sonically? I read about how you should place your high end gear on isolating tiptoes and such, and that it makes an improvement. I have never gone that far with my stereo. But now I have a DAC on top of a pulsating subwoofer!

Thanks for the replies everyone.The subwoofer is 100+ pounds, has a 12" woofer, with 400 watts behind it. You can feel the frequencies when you touch the outer cabinet, it's not completly isolated for sure. But stout.
For one thing, the DAC gives me unbelievable bass response all the way down!
I guess I'll have to find a new home for it (hopefully without using longer cables to my preamp.)
Putting stuff on a sub-woofer is a bad idea and I don't recommend it.However I'm getting by with it and you may too. It's my study system and only played at background music levels so that helps. However it sounds good and turning off the woofer doesn't seem to affect the sound outside of the lowest octave.
So move it elsewhere and see if it sounds better. If not, you're in business at least for now, you can always optimize it further later.Remember that most of these tweaks you read about are highly dependent upon the particular equipment in use and sometimes the particular unit. Thus you really need to listen for what matters with YOUR gear and trust your ears.
Good luck, Rick
I put a wooden cat on my subwoofer, and it usually comes alive and takes a leap during a loud movie.I wouldn't put electronics on top of it, whether you think it could impact the sound or not.
Oh, I definitly think it could impact the sound....Whether it will or not however is dependent upon many factor including loudness, sub-woofer construction, equipment vibration sensitivity and choice of listening material. However if cats shook off mine I definitely wouldn't put electronics on it either!
Since reading the original post, I've been mulling this over and think I'll do some simple measurements to see if they show anything. I've got both a receiver and CD player stacked on it and should be able to easily observe and isolate any problems running an FFT with my computer's sound card while sweeping the woofer.
If I see anything, I'll fix it even if it means moving the stuff because, as an audiophile, I'm willing to fix measured problems even if I can't hear them...
Regard, Rick
You might as well put the turntable there too. Seriously, many components, especially capacitors, can be microphonic. Cables, too.
> You might as well put the turntable there too.That's a **gross** exaggeration, of course. Capacitors and cables may be microphonic (at least, thinking so feeds that "audiophilia nervosa"-style of hypochondria ;-> ), but phono cartridges must be **many** orders of magnitude more so. If the poster put a turntable on top of a subwoofer, he wouldn't be saying "I can't hear anything wrong, but what do you all think?"
I wouldn't put a pbandj sandwich on a sub, let alone a piece of gear. If nothing else, place it on the floor.
I hope this was a joke.
