Great to hear middlemass. It does give me some pleasure, since I discovered the the active ingredient that gives the incredible improvement you’re hearing, in 2019. I didn’t invent the ingredient, I just discovered its benefit for audio.
I highly recommend you (or any members who have Q45T) should create one of these. All the double adapter pins should be painted with the black potion (both sides of the top one third of each pin is all that’s necessary). I made this today for a total cost of $22, from components bought at the supermarket (in Australia where I live). It improves the sound far more than my $12,000 power conditioner (brand name withheld so as not to unduly embarrass any manufacturer). You can plug low power audio devices into it, but I just leave it as is, with nothing plugged in. The benefit is, you’re not painting your expensive audio gear with the Q45T, but you’re getting incredible benefit for very low cost. And you can remove it any time you like, to compare with or without. And it’s portable.
