Is DEQX a game changer?

Al, you and I are both old enough to know that some questions are best not asked. I'm "freeze tagging" on the DEQX's analogue functionality viz my phono. The thought that my Ref 5 SE could be an irrelevant artifact is too difficult to bear.

I had the same reaction when Excel/Lotis spreadsheet software obsoleted 14 column spreadsheet paper. To this day, I refuse to use Excel. I ask the kids to run my spreadsheets when I need that work done. I love my 14 column spreadsheets, white vinyl eraser and Pentel .5mm mechanical pencil. Even to this day, nobody can run a "10-key" faster than me.

Very interesting to hear the DAC function sounds at least as good as the ARC Ref CD 8--impressive! And it seems the preamp function is excellent as well. Do we have another OPPO here? Great usefulness and great value?

I have both digital and analogue sources going to the DEQX model HDP4.The digital sources run directly to the DEQX, and the analogue sources pass through a conventional preamp before going to the DEQX. There is really no reason to use a conventional preamp in addition to the HDP4 model, other than the increased number of inputs it affords. The preamp section in the HDP4 is of a very high quality, as are the A/D and D/A convertors.

For those who would contemplate learning how to do the calibrations themselves, make sure you have a lot of free time.

I am nearly 60 and although I also have around 4000 CDs, a few dozen SACDs and (at last count) around 54,000 (!?) mostly FLAC digital files (Rock, Hard Rock, Blues, Folk, Indie, Electronic, Folk) I still prefer Vinyl through my DEQX - 2 TTs via phono amps. 3 very fine preamps are now in other rooms or unused and will never be in the main system again

Drewan ...can I use the transport in my CD-8 to play SACD discs? I don't know what the bit/FR is with SACD or other high resolution discs. This is new territory for me. I think redbook CD is 16 bit/44.1 KHz. What is SACD?

What about hi-rez computer downloads? I have no idea what is out there.
