Transports & DAC's ?

hello to all, I have been doing some home work for a few days and what I have come across is that companys like (PS Audio, Theta Digital, Rotel ....) among others for the most part use the Philips (cdm 9 pro) laser assembly, which is supposed to be one of the best around. now I use
a Rotel rdd980 transport. my friend uses 2 Theta Data II's
& a PS audio transports..acording to all these companies philips promised to maintain parts through at least 2005 but as it stands now these laser assem.. are no longer made or repairable..the companies mentioned above were very cooperative with info for me. at philips no one knows what the hell I'm talkin about..I know Theta now in their
$4000 tranport use a Pioneer assembly which can't hold a candle to the cdm 9pro..I've heard you can find them refurbished from overseas in Europe..now I've come to looking into the Toshiba SD9200 as a transport or the Adcom
GCD750 cd player which as a bonus uses balanced outputs. I'm also using a Krell Stealth dac & a pair of Parasound HCA3500's & a pair of Mirage M1-si's..I'm trying to get the jitter correction #'s on these 2 units but to no avail at this writing..thx for any informative input anyone could supply..knowledge is king!
