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?

The McCormack and the Belles are excellent. I'm not fond of the Aragon as I find it to be bright sounding. I don't believe the solidstate rectification is the problem.

it's hard for others who can't hear your system to pin down what's causing your problems, but Stereo5's concerns about metal dome tweeters would sure top my list of things to consider.
quite honestly, I don't know if this is a brand new (never used) pre-amp or one that needs new tubes. If brand new, then hook it up, turn it on with a source whenever you get home and leave the room while letting it play. this needs to be burned (broken in). devices will sound extremely harsh until properly broken it. this could take days literally. So, before you spend large sums replacing tubes and other things, just turn on some music, let it play for the recommended burn in period and then come out and play. If it is brand new, I bet it will sound much better in about a week after burning in. If it is used or an older demo unit, then maybe the tubes need replacing. But, it could be your source, cable/equipment interaction, etc. A little bit late but, it is always a good idea to borrow a unit or give the dealer a credit card number and take the unit home for a week to listen before purchasing. I don't deal with dealers that won't let me take the unit home for a week or so first. I give them my credit card information, but with the agreement that if I don't like it, I can bring it back.

I've been using the AI mod3, 3a, and 3b, for some time now and can honestly say it is very revealing and will force you to upgade everything else to max out its potential. I've been there. Unfortunitly IMHO the SS Rotel needs to replaced with tubes... and personally I don't think the Sony BRP is a good cd transport. And forget the "cheapo" cables... buy Crimson CAbles and be done with it.

It might be easyier to get a less revealing preamp...

Good luck

Actually, I feel my problem is resolve. I set the left and right knob to 6:00, and the main knob to around 8:00. I listen to it all night last night, no harshess, and no "s" sound. It seems the bass doesn't kick in when the main knob is set to very low (close to 6:00). Anyway, I will do more testing.

But still, I am seriously considering upgrading my amp due to the upgrade bug, but my budget is < $1000. I am leaning towards a DNA-1, but also comparing to Belles 150A, or PS Audio HCA-2.
I spot another one, a Mcintosh 2105. I can't really find a review for that probably because of its age. But it is really eye catching. How is 30 yrs old Mcintosh it compared to more recent SS amp like the DNA-1 or Belles 150A?
