Break in period

Yamaha, Sony, Denon, Pioneer.....do these guys use the same quality parts as say ARC?

They make designs mostly using transistors. The pre-amp you refer to uses tubes. The quality of the individual parts cannot be directly compared as the designs are quite different. Tube preamps run at much higher voltages and need higher quality (rated) components.

Shadorne, your last post got me thinking. . . what could possibly explain the 1200 hrs to complete break in for my TEAC X-01 Limited CDP? Perhaps Crypto-tubes. . . really tiny. . . really well hidden. . . perhaps kept secret by TEAC. . . real conspiratorial like? Or is it just a truly badd bad kind-a-hopeless solid state design cobbled together from bargain-basement parts. . . perhaps just one of them multi-K$$$ attractive boat-anchors which got foisted onto the financial shoulders of this poor audiofool? I should get rid of it ASAP. . . now that I think of it, I should dunk my Toyota van too, after all its all-solid-state stereo took about 200 hours to sound decent as well!

Shadorne, I just don't follow what you are saying.

Guidocorona,

I gave you a few brand names of a few consistent sounding, respected engineering and manufacturing firms (mass produced) that are well known reliable products. If, as you say yourself, your gear changes response or requires an extensive break-in of over 200 and up to 1200 hours then that would not be my preferred choice that's all. However, I don't agree nor would I dare suggest that your fantastic gear are just useless boat anchors or that you should dump your truck because of this. Peace. We probably have different interpretations of the differences heard from repeated playing of music. (what I call getting habituated or new insights from repetitive playing of music may actually all be "break-in", certainly I believe that ears/brain can be trained to become more discerning and repetition is a big part of it - so the listening experience is never identical)

Psychosomatic, huh? Or in other words. . . delusional, eh? And I thought that in 50 years of music I had reached a small modicum of insight. . . now I am really staggered by the harsh impact of factual reality!
