experience is the best teacher.
there are some threads that are enlightening for many reasons.
there are others which serve no useful purpose.
asking for opinions is not a substitute for learning through one's own efforts.
requesting opinions concerning what is the best preamp, cd player, amp under $2000, etc., does not substitute for doing the hard work which will ultimately provide the answer for oneself.
i don't think any of my comments are insulting or belittling.
i am just speaking from my own personal experience and observation.
here is an example of my approach.
i am currently trying to decide whether to purchase a raysonic 128, having auditioned a 168, which was not to my taste. i would not ask the question:
is the 128 better than the 168 ?
i might ask owners of the 128 about their experiences with the 128.
