Just got Audible Illusions L1, but it sound harsh


I just got a Audible Illusions L1 preamp to replace my Rotel RC 1070. I can hear it is much more detail, it sounds more forward and bigger sound stage. But I also found it too harsh. Especially in vocal, the "s" sound is very loud and quite alloying. I don't have it in my RC 1070, but at the same time, it doesn't sound as musical. It is just like sing behind a curtain. I don't hear that detail, but also, those annoying "s" sound is "filter" out. Is it a characteristic of this preamp? Is there any thing I can do? I am using a Rotel RB 1080 amp. Should I try another preamp? Or try another amp?

Have you given time to allow the unit and associated cables, all which had to be moved around, to settle in? It could be that with 24 hour a day play for a few days that the preamp and cables will settle in and the harshness could mellow out. How long has the preamp been up and running in your system untouched? If that isn't it, maybe a tube change is necessary, or maybe the L1 could be a poor match in your system.
The pre-amp has been running for an hour

1 hour is not enough time to start doing critical listening. Your preamp and cables need more time than that to settle in before you make judgements. Give it at least a couple days then if still necessary start thinking about tweaking things.
Face, any component and the associated cables need time to settle in. 1 hour? Not enough imo. Is 1 hour adequate for you to start making assumptions about performance? At minimum I wouldn't conclude anything for at least 24 hrs after putting new (used) gear in my rig.
