Sound becomes less open/smeared (less detailed)
Hi all.
Strange phenomena but when I play music (and leave my set on for days) the sound becomes less detailed (smeared). I know it's the pre amp (Bryston BP25).
After switching it off and then switching it on (after waiting a couple of minutes) the sound is more open and detailed.
It's strange because I also have the general experience when listening to stuff which has been turned on not long ago, sound is a little harsh and grainy at first. With use it gets more fluid and smooth. But my experience with this preamp is many times the opposite (but just after many hours).
Can someone explain this behaviour?
@devinplombier : it may seem remarkable (and in a way I am looking for confirmation) but I am really interested in experiences and clues about the deteriorating sound As a matter of fact I already measured the "blue ones" but they seemed ok, so suggestions/ideas/clues remain welcome. Electrolytics are the first ones to suspect (and some pictures I found on the net show replacements) but maybe I am overlooking something? |
I bought a Revox B215 cassette deck last year. It sounded fine so I thought. I sent it out to get recapped and checked out. I was very surprised and delighted when I plugged it in for a listen when it came back. MUCH improved. I think all gear after 20 plus years needs recapping. Keep us posted. Joe |
