I really don't know how long it will take to break-in. It just gets better everytime I pop in a CD. Please be advised that I may use bold statements about my findings here. I would advise to have a listen for yourself if possible.
Here are my findings, so far so good:
Brand new Out of box: A-
After one Week: A+++
The Talk Thunder 3.1b is really an amazing CD Player. I listened to a variety of music: Bad Plus "Give", Black Light Syndrome"Duende", Wynton Marsalis "quartet", Pancho Sanchez, Vivaldi, Patricia Barber CDs etc. The Thunder 3.1b never stopped to amaze me. The clarity and detail that I never heard before from my previous CD player was all present. Sound-Staging and depth is excellent. Bass resolution was excellent plus, if it is in the recording it will find it! You can literally resolve how many bass players in Ray Brown's "SuperBass2". Wood instruments sounded like wood! The dynamics and musical timing flows with accuracy. It is not Etched or Fatiguing. Words may not be enough to convey my findings but it really sounded F_ck__ Good! Unfortunately, poor recordings sounded poor. I find my self listenging to all sorts of music uncluding Baroque...those instruments...I think this CD player is made for musicians who knows what instruments sounded and for others to learn.
The highlights of the Talk Thunder 3.1b are:
Amazing bass resolution and clarity.
Excellent Realism of instruments.
Micro-dynamics.
Organic Sound.
I am really happy with it and that's all that matters
