Uh... no, not really.
So many variables at play when it comes to the amplification of audio.
I see a lot of talk on this forum about amp quality being of little importance, and I have to (respectfully) call bull$hit on that.
I can easily hear the differences between tubes, transistors, digital amps (class D) etc. I can tell quality with my ears as well.
Most consumer stuff sounds like garbage to me, but yes, I am an audio snob.
There are some who think MP3's are an acceptable audio format, and I most definitely "think not".
YMMV, but I have heard serous high end amplification, and there is most definitely a difference in all areas of quality. From sound performance to build quality to long term reliability.
Of course, there are exceptions to this, "it takes money for quality" philosophy.
That's why I am here!
Gotta go pick up my girly unit from work, she didn't want to drive since we are expecting snow here in Atlanta (quit laughing you Canucks!).
Anyway, sirquack, peace and much respect, not trying to be combative here. I really do dig this cool forum and all the info I have gotten here.
And besides, $4800.00 US is chicken feed in audiophile circles!
You want 'high end"? Look at this: http://www.mbl-usa.com/Default.aspx
