Sorlowski,
I am not recommending to "roll" tubes. They simply get old & begin to loose definition & sound murky. I retubed mine (now sold) many years ago to a great positive effect. A friend changed the tubes for me. It wasn't so difficult a job.
Based on your description it sounds like your tubes are old. Vinyl is better, but the Audio Aero is not a slouch. One of the most "analogue" sounding CD players.
