If anything, the 777es is a tad on the "warm side" insofar as sound goes. Kevziek, I recommend that you perhaps consider what your speakers are like because of the description that you gave of the 777es' sound is well, diametrically opposed to what mine sounds like anyway.
The only criticism that I'd give the Sony over the newer generation CD players is that they are not the very last word in outright resolution.
But in light of it's other shining virtues as listed by Fna, I'm happy to live with this "compromise". Put simply, it's a very enjoyable & satisfying listen.
Like Fna, I'd originally sold my 777es only to buy it back from the same person 4 years later.
Will I get a new machine like an audiophile grade SACD or DVD-A player? In time yes, but I will NEVER sell the CDP-X777es again!
