My thoughts on bias below… kind of off topic… but aligns with better trying to understand and view one’s own biases…
I’ve been saying for years that we are all made up of Biases… all are learned from our environments, friends, family, experiences, the society we live in, etc… it is being aware and seeking out why we have these biases that I think more people need to look inwards and determine if they are good or bad biases… biases are kind of the new term to define fight or flight lol… they tell us how to react based on the above-learned behaviors or shared thoughts.
More importantly, I think everyone should constantly be re-evaluating their own biases to ensure that we are not allowing them to steer us wrong… there are always outliers, and biases can be extremely wrong especially the societal/learned/group think ones… so, I ask you to stop… think and dwell on what you are doing and try and determine where that bias is coming from and how best to understand your own actions based on that bias… recognizing that everything we do, decisions we make are technically a bias, is a fun mental game to play and think on… try and determine where you learned your biases 
it is fun and can be very eye opening.
Cheers… I enjoy these types of discussions… but, I’ll let you all get back to discussing amps, and how they do or do not sound the same… I personally think they sound different depending on implementation and technology used… though there is a lot that is, very similar if not the same in various line-ups… THX seems to be a big culprit of this in my opinion… anyhow… back to work I go!
