I consider components based on
1) my exp
2) components reputation ie reviews, blogs , dis boards etc
3) actual pics of the guts, w/oa pic of the guts I would not consider buying as per Kevin Deals' advice over at Upscale Audio.
4) price consideations, what can i afford in paypal debt
Then to get units up to high fidelity, one must take out low quality parts and add in new high tech stuff, new caps, new resistors,
Then other monir tweeks, new DIY power cords, new high tech IC's. super tubes = ie Telefunkens, Svetalan 6550s..
all these wteeks add up to going higher up Mt Everest basecamps.
Have I attained, or ever will attain reaching the pinnacle of Mt Everest?
What i am hearing in my modded setup, I can see glimpses of the pinnacle breaking through the clouds.. and its just awesome,,been waiting some 50 years to reach this basecamp.
old audiophile from mid 70's here.
High Fidelity is no myth, no biased opinion,
Some components are inherently high fidelity potential, while others, even with extensive mods,,will never get you up the mountain to glimpse the summit.
I have another 2 years, and another ohhh $5K, I should be at a nice basecamp where I can grasp the summit.
High Fidelity is no myth,
Although elusive, it does exist outside of opinionated bias...., The Real Deal is for real.
watch the snakeoil offerings along the way up,,
