Thank you for the compliments.
In terms of your definition, then yes, I am enthusiastic about high fidelity sound, so perhaps an audiophile after all, but it's not a hobby for me.
For example, did I audition a single piece of my equipment, well actually no. I have made changes or upgraded without auditioning, nothing more than reading a few reviews. Each change that has been made did make some difference to the sound, some more than others. Some changes were made simply to make life easier as I age, reducing the weight of a 50kg amp to a 10 kg amp for example, for ease of moving/cleaning etc.
The biggest change was the recent "downgrade" from 3 way floor standing speakers to 2 way stand mount speakers, but somewhat of an upgrade from Gold to Platinum. I am still blown away at how different and just how good the sound now is, resulting in significantly more hours relaxing, listening to music.
To be honest I rarely listen to CDs or Vinyl now and 98% of my listening is streaming, so I often have thoughts of selling off the record deck and CD transport. As one ages we get less willing or able to continually get up off the chair.
