I have used a Sony DVP-S7000 as a transport since the Theta Chroma came out, and at the time I was driving a pair of Carver Platinum Amazings with Quicksilver 8417 mono's. The results were spectacular, in my estimation, and I have never turned back. I am now on my third DVP-S7000, and my DAC is a Metronome C1A with NOS Tesla ECC83 output tubes going into a Flora-EX DT preamp then to an Art Audio Symphony ll amplifier driving a pair of Ocellia Tilias. I recently upgraded my power cables and interconnects, and I have never heard anything so fine, not at a show, a demo at a high end store, nor from the home systems of any of the many people I have had the pleasure and the honor of visiting in of over 30 years of audiophilia, including systems costing many times what I have spent on my (relatively) modest rig. Maybe it's because this DVD player has two lasers, one for dvd and another for cd playback, but this one seems to be the exception to the trend presented here.
I sometimes get tempted to try something else, and then I listen to what I have and think of the words of my departed uncle/mentor, who told me "Don't fix it if it ain't broke".
Thanks for your kind attention.
