You stated that the MM's had too much bass. Do you mean the omni's? Some people here have complained there was not enough bass response for the cardioid, but that wasn't my experience all. I found the MM's to have a lot of detail with that Sennheiser sound.
Agreed. To my ears, the MM's cards ( HLSC-1) are great sounding mics for a nice price.
I have used the Highline mic's for a short while. It was to compare them to the Core Sound Stealthy Cardiod's ( the $ 250 ones ).
I record basically only hardrock and metal. A lot of those bands use the double bass frequently. The way they sound on the MM's is absolutely terrible. Sometimes even overloaded ( and the recordingsettings were fine ). They simply have way too much bass to handle things like double bassdrums. That's why binaural's are out of the question for me. They may work well for other music but not for what I do.
I have never had problems with my Core Sound set. They catch live music the way I like it.
Now about the lack of bass...I have made many recordings where I've had plenty of bass. It all depends on how a gig sounds like.
I feel Core Sound catches a concert the way it really sounded like.
I'm glad I did find mic's that I am totally happy about. It may not be other people's taste. But I love them and that's what it's all about.
That said I'm sure other people may like other mic's better and that's all cool. To each it's own.
