I've had my current set up for about a year and I'm very happy with it, it's just that it lacks bass at the bottom end. What I'd call the top end (higher frequency) bass is there, it's just the bottom (lower frequency bass) is lacking. My room is very small 2m x 4m with a pair of cupboards along the longest side, which my Tannoy F4 Custom's sit each side of. My source is uncompressed media files feeding into a DACMagic via a CA TOSLink cable. The DAC then feeds into an Arcam A28 via a Chord Chameleon Silver Plus. My speaker cable is CA 400 series wired as bi-wired. Several friends of mine who are into HiFi say that the system sounds very good, but agree with me that bass is lacking. The room has a wooden floor with a rug and is suspended over a walkway. Sorry, if this sounds like loads of detail, but some of you might know what the problem is. I know it’s not the Chord Chameleon Silver Plus as I tried six different cables when I set the system up and that gave me the most detail as well as the most bass. I’m thinking of adding a sub but could changing the speaker cable help, or is it simply the room layout or speakers. All help and advice appreciated. Cheers!
