Caporegime
Did it make it sound better?
Of course, my tea tastes so much better since it is using one of these I am tempted to make one out of silver.
(I've also actually made interconnectors using cables with a (percentage) silver core using solder that has 5% silver content).
Both power cables and power blocks can make a difference. Subjective on the former and can be very expensive on the later. Don't forget all the vibration damping legs and mats.
Been there, done that, at least with the vibration damping, (not the power block)…I used to make jokes about suspending components on fishing wire off the ceiling and/sitting the CD player on a block of cheese as a way of eliminating vibration in a HiFi Forum, people actually thought I gave it a go and asked me what improvements it yielded.
