Not only the Pass amp needs around 200hrs of break in, it also needs at least 1hr of warm up every time you turn it on to do some listening.
Give it a chance. Don’t think about trying to hear a $5,000 improvement. Just enjoy the music and you’ll be able to pick out subtle details and qualities you haven’t heard before. The refinements don’t always jump at you right away.
Good luck!
Pass INT-25 better than Wilsenton R8?
I have recently purchased a Pass Labs INT-25. It replaced a Wilsenton R8 with NOS tubes (EL-34). I feel that the sound im getting from the Pass is not 5000.00 better. Has anyone purchased a INT-25 and not been blown away from the sound? I do think that the 25 has a wider soundstage.
