Philips 963 Sound Modifications

I have read enough threads here and Audio Asylum to realized there are a lot of modifications going on with this model. Could someone recommend a modifier who concentrates on the CD/SACD sound rather than video. No interest in video or surround sound. Primary system is all tubes, Aronov amp, CJ preamp,etc. feeding Swans Allures speakers. Thanks in advance for any recommendations!
