My desk is solid oak so bass and mids resonate through it beautifully. Especially since the speakers sit directly on it and they are heavy (3.5 kg). The problem with this is that my monitor sits directly between the speakers and it's in the middle of the oak so there are sound waves coming from left and right and up through the stand resulting in boomy resonance.



Here is how I have overcome this.





The pillow does two jobs - it deadens vibrations in the monitor and, because the monitors and speakers are arranged  like a box against the wall, it helps to dampen resonances / amplification there too:

So the problem isn't so much "boomy one-note bass", it's monitor vibration?  Maybe buzzing or rattling?

I'll just throw-out some random suggestions...

- They make foam speaker/monitor isolators.  Now in general, I think these things are over-hyped and over-priced, and I'll bet in most situations there's no audible difference (in a blind test).    But if you have a vibration problem, they might be helpful.    You can try making your own (hopefully you can find some black foam), and you can try putting some foam rubber under the video monitor too.

- Maybe some stick-on rubber feet on the video monitor & speakers would help (if there are no rubber feet already).

- Maybe a just different video monitor that's not so prone to vibration.

- You can attach a shelf to the wall, and put the speakers on the shelf.    Or, you can get some speaker stands, but this will take-up space in the room.

- You can get a TV/Monitor wall-mount bracket and get the monitor off the desk.

The speakers (and speaker placement) are almost always the weak point, as well as the biggest effect on the character/quality of the sound.    Adding a good subwoofer might help.  (You probably don't want a cheap "one-note boomy" sub...  You want an accurate subwoofer.    I'm not saying there's anything wrong with your speakers...    It's all relative and  I don't know anything about those speakers, but I'm just saying that some Wilson Audio speakers (which I've never heard) would probably be a BIG improvement! 

Otherwise, there are probably no audible defects in your chain.  You may hear some noise from your amplifier, since you are so close to the speakers.    But, being so close to the speakers also makes it very unlikely that you are "running out of power" and driving your amp into distortion.

The SoX resampler & "bit-perfect" setting is probably having no audible effect either (in a proper blind listening test).    Are trying to bypass the Windows resampler?  Why are you resampling?  I assume you realize that when you resample, the data-stream is no longer bit-perfect?

I forgot to mention room acoustics!!!!!

The white keyboard surrounded by black computer, black monitor, black joystick, black mouse, black speakers, black DAC, black mouse mat and black armchair is odd.

You could make some wedges\stands so you can angle the speakers towards your ears.

Are those speakers ported? front or back? maybe make a bung to block the porthole.
Who are you and how did you get in here ?

Ideally you'd place the speakers facing rather than along the long side of the room. Either way the speakers should be atleast 10" from the front wall.

- You can get a TV/Monitor wall-mount bracket and get the monitor off the desk.

Thus you'll gain also enough room to place your wirsts upon while tiping and using the mouse: your back will thanks you a lot!

You didn't need a smiley. It takes "lucky" placement to get reasonable bass out of small speakers, and it's rarely the placement that optimises the sound quality of the rest of the frequency range. Having a well placed sub to take care of bass frequencies frees you to place the small speakers in a better location. However, sometimes the room is just too small for this to work, and a sub is overwhelming, or bad value for money for the difference it makes. Often the biggest audible difference is outside the room, which can be a bigger problem!

The best sounding speakers don't sit at the back of a desk near the wall of a room. Ideally you need the sound to hit your ears before it hits anything else - or at least, any reflections need to reach your ears as long as possible after the direct sound, not all merged in with it.

I wouldn't change any of the equipment. I'm not sure about the fb2k resampler settings, but I wouldn't worry about them too much for now.

What I'd do is try the speakers in different positions around the room. If you don't have stands, try cardboard boxes or piles of books to support them at ear height (just for testing - you need proper stands if you find a good sounding position away from the desk). If you have friends around and they already think you're mad, get them to hold the speakers while you listen. You might find a location that works really well.

If you primarily listen at your desk, then you may have the best location already. You could try raising them, and/or bringing everything a little away from the wall, but it may sound worse.

Some people do some funky things... (just used Google Image Search with the terms ikea expedit record dj because I knew I'd seen some "interesting" speaker mounting techniques there)...

Is there any particular reason why you didn't go with near-field studio monitors?

No it's definately one-note resonance

I made my own! Raising them off the oak makes a massive difference! The only problem is I only had green foam from a gardening kneeling pad. [/quote]

My chair is like 5-10 cm too low for this! I need a better one...

Haha, that's brilliant. I'm sure they sound good!

These speakers were hand-me-downs, same with the amp! I might upgrade, but monitors are damn expensive.





Thank you all for your suggestions, They were all very good!
