I would just leave them as they are, discoloration is not likely to affect the sound. If it's the visual aspect that bothers then just cover the grills with speaker clothing.
Hum is most often caused by grounding issues. Check your cables and test if removing turntable ground wire actually removes the hum or makes it worse.
Audio Technica cardridges typically have pronounced top end, nothing much that can be done with that. Anyway it's good to check turntable...
EQ is totally ok to, that's why there is DSP in the active woofer amplifiers ;)
Please use the "camera" button in the upper left corner to save screenshots and keep SPL range at 60dB scale. If you follow the general instruction to measure at 75dB then maximum could be set to 95dB and minimum...
If I have understood correctly, sound quality benefits if any of the MQA process would be in analog to analog conversion. In that case the sound quality comparisons should be done between original analog source (master?) and output of the DAC signal.
I'm not convinced that the potential...
Let's get some action in to this thread and keep those chains tight :cool:
My other [vintage] ride from those days of activity, 26" FS MTB. Did build up this one from parts, bits and pieces, including the wheels. Still does the job.
I will present following just to show the power of AA XD model's DSP function.
The room layout is as pictured below, please note that it might not be totally accurate in relative dimensions.
There is a practical room simulation tool in REW which I run twice with different width calculations...
I think everyone should read and then re-read what Blue58 said.
Just to clear things up, by toe out I actually mean toe in but in a way where the aim of the speakers would cross somewhere 1-2m behind my head. From my listening spot I'm just about to see the middle sidewalls of the speaker...
I have slight toe out on mine but experimenting is worth doing. I would also like to try them directly on the front wall but I have some cabinetry behind them so not possible but like I said, everything depends on the room.
