Hi
Revisiting this thread after my Breville Coffee Grinder went kaput and ... The Gaggia is still churning along. I am still looking for a CSR. Lance Hedrick is good to a point but his video are too long and lose in the coffee-nerdy parts, that are too similar to High ENd Audiophiles. Yes, he retains a modicum of science in his videos/review but for the most part, the "body", and entire complications of "flavors" from the coffee is to me the same as what I woudl read in S'Phile or TAS, IOW: THese means, whatever the reader or viewer may want to make of these words.
On that I did recant
I did in a post recant a little bit my impression on Hofmann... I watched him a lot more . My conclusions aligned with some part of
@Keith_W post, some part I am quoting here: :
I watch Hoffman videos and I marvel at his sensitive tastebuds. If you ask me, I can't taste hints of bergamot, madagascar vanilla, dark stone fruit or whatever else he is using to describe the coffee. ..<snip>.
And I now more than ever see him as an equivalent of S'Phile or TAS writers. What is worse is that Science is infused (pun intended) in all of this, to derive conclusions that, in most cases are that I can taste (hear) better than you because I have better (ears/taste buds) and more expensive gears (Coffee Machine/grinders/Amplifiers/speakers).
ASR has changed my mindset profoundly: Before ASR, I was throwing money at Audio dissatisfaction. I was ready to invest >$30 K in a pair of speakers and about the same in an amp!!! I wnet and acquired several headphones including vastly expensive ones.. and their amps... That was around 2012~2014
In 2018, I am today immensely satisfied by a speaker-based system system that can be acquired today on Amazon for less $2500 and it is full range (20 Hz to 20,000 Hz) and accurate. measurably so.
Going forward: I had this morning my coffee fix from a pressurized portafilter.. Truly not the same .. I will go ahead and acquire a Hibrew G5 Coffee Grinder or equivalent, use the Gaggia until it die0 or perhaps acquire a Breville Bamabino Plus.. End (of the coffee) game

. Not entirely satisfactory but in the absence of an ASR for coffee, a CSR if you will ... I'll save my money...
Peace
