In response to the laser 3weeks is nothing myself and others have had even cheap cd players for years also please keep in mind the Sony 5400 cd-sacd player has 2 lasers for the sacd has it's own decoder and needs several hundred hours to run in , if you don;t have a sacd disc
then Buy one they sound great and you can run in a new unit with the sacd side first.
I have my first initial impressions available on my Modwright Ultimate mod for the Sony 5400 ,and even with only 75 hours on it , and 400 is needed for full breakin
it is very very natural sounding the music just flows out if the speakers ,sure it is somewhat closed in still and the fron to back layering is not quite there yet ,but the timber of a stringed instrument like a Cello or a drum head has great timber with outstanding seperation of instruments ,and being it is not even close to being runin that is saying a lot .I can say with conviction
any $10k unit will have a hard time following this player
just checkout how extensive this build is at Modwright , also the seperate Vacuum tube power supply probably weighs
10 lbs on it's own and the 6sn7 Vacuum tubes for the New analog section give it much more dimention and Make the stock unit sound broken.
Dan at Modwright hit this one out of the park !
