    Is "room correction" such as Dirac, ARC, audyssey actually correcting for the room?

    From what i have learned the only proper way to actually correct the room is to change the actually change the room accoustics itself, you don't have to build a full anechoic chamber to get significant benefits there. The main thing EQ is good for is correcting for flawed speakers and as we...

    Looking for music with meaningful ultrasonic content

    I plan to do compare sample-rates blind later (when i have better speakers) but i am already looking for good test tracks. I want to see how high in frequency i can detect a lowpass filter once i have good equipment. I am especially interested in testing if ultrasonics above say 24 Khz can...

    I made a sample rate blind-test (192 vs 48)

    I remember doing a similar test years ago with this track and i though the 192 version was better (9 times out of 10) https://www.mediafire.com/folder/u2ja7bkonannf/sample_rate_blidntest I used audacity to downsample and upsample (for the 48 KS/s version). I used https://www.random.org/...

    Is there any good DC-coupled amps to buy?

    I have read that a lot of amplifiers will not actually reproduce direct current but i havn't been able to find good information regarding this. With most reviews i see a small dropoff at 10hz, is that due to the amplifier itself not reproducing DC or is it due to limitations when it comes to...

    Looking for a new AMP with flat frequency response and 40+ W

    I have looked at the aiyima A07 and while that would probably be better than my old AMD (where one of the channels stopped working) i would like to have better frequency response than this: The much more expensive topping LA90 seems to offer what i need right now but it sucks only getting...
