If $80k doesn’t provide for a fairly uninhibited*, transportive musical experience in a home setup, nothing will. For that amount of money one should, or certainly can have a full-range spectrum (honest 20-25Hz, at full tilt, on up), practically unlimited dynamics, close to fully scaled, sublimely resolved, highly transparent, coherent and tonally natural presentation. With gear bought used, incl. a DIY-approach and an open mind with regard to (pro) gear segment - much cheaper than that.
People who believe top level audio audio gear and sound can only be had from known high-end brands in new condition and latest design iteration, in addition to a variety of self-imposed restrictions (incl. interior decoration/aesthetic demands) and a dogmatic/conservative approach to audiophilia, are likely to find it difficult coming to above mentioned conclusion. However if one really wants to there’s nothing than yourself holding you back from achieving sonics as described, and at a less than stratospheric price level.
*By ’uninhibited’ I mean what’s referred to later in the top paragraph.
