I have tried the 404, and 507 and Lambda Signature. All of them have that peak, or etch in the upper frequencies which I cannot stand.
I tried the LNS and it was fine in this area but it did not sound very good either.
Is there any Lambda, Airbow or similar that sounds good and doses not have this problem?
I have read some reports that the 404LE does not have this issue. Others say it does.
I would appreciate some advice.
