I have a CD67SE ... on its own it's not a very good transport since there is quite a lot of jitter on the digital out. So if you go the DAC route be sure to either buy a DAC which resamples and reclocks the data stream to remove jitter, or buy a Monarchy DIP or similar to reduce the jitter. I use a Monarchy audio 22A DAC and the DIP made more difference than the DAC on its own, indicating that the CD67/63 sound is more jitter limited than DAC or output stage limited.
In summary I think a CD63SE may not be capable of justifying a $1500 DAC. My DAC and DIP cost $350 together and made a good improvement over the CD67, but the CD67 is still the weak link.
