Unless the bugger spends a million or two US dollars - immediate gratification. End game system like Reference MBL or Burmester (with Focal Grande Utopia EM & full Odin 2 cables). Yum Yum.

Not even close. My endgame system looks like this:

Power Amplifier: Dan D'Agostino Momentum Monoblocks
Preamplifier: Burmester 808 Mk5
CD Player: Burmester 069
Turntable: Transrotor Artus
Tonearm: Vertere Reference
Cartridge: Clearaudio Goldfinger Reference
Streamer: Burmester 111 Musiccentre
Speakers: Focal Grande Utopia EM
Subwoofer: Focal Sub Utopia EM (3 units)
Interconnects: Nordost Odin 2
Speaker Cables: Siltech Triple Crown

Not even close to getting any of the above. Sigh

There is NEVER enough bass. Like what htkaki (Max of Maxx Audio - great guy) says, "if your glass ain't shaking, you ain't got bass". I like my my glass panes and my ceiling to be "vibrating in tune with my subs" and my two mutts to run helter skelter, hence the three stackable Focal subs. EM = electromagnetic woofers. Yummy.

Basically "sufficient" bass extends your soundstage. One needs a huge room though cos 20Hz has a 40 foot wavelength. Subsonic waves are the ones you feel, not hear (unless you are a dog).

Getting a sub is the easiest part. Sneaking it past the missus is the trickier part and the hardest part is to set the bugger up.
