You should probably ask Detlof for a full account. My spontaneous impressions were iffy: the 988's had the voicing of the 989 without the extension and, vs. the 63, the reproduced spectrum was a bit lower -- a bit pronounced in the mid-bass if you will.
However, this was not @ home & the set-up was less than ideal: speakers were driven by the (new) Quad tubes & the quad cdp. In THIS set-up, I preferred the 989 and a pair of 63. Last, I listened to classical and one Grusin cd... hardly an extensive audition.
