I use Kara with a pair of Tyrs. 1x and 4x selected depending on my mood. 1x is Laird back and fluid, often great when I'd like to relax or just have the music on as BGM. 4x brings on more excitement and impact, it works well when I want to be more immersed in music or TV/Movie.
Please report back what you think of x4 vs x1.
After an afternoon and evening session with Kara using 4x mode, I have to say that
@leafy7382 's impression is spot on.
Listening to classical, I was impressed by the added weight and clarity that 4x mode brought to tympani, double bass, and cellos. This wasn't added bass per se, but more presence if you will, better definition.
On rock fare, there seemed to be greater dynamics.
At first, I thought that 1x mode seemed a bit smoother, but after some back and forth between 1x and 4x while trying to volume match, I'm not so sure.
I thought 4x sounded a bit grainy with Freya S. I have no such complaints with Kara's 4x mode.
I detected no loss of detail/resolution with Kara's 4x mode. I appreciated the perceived greater dynamics.
The only downside that I've encountered so far, is that 4x shows that one of my phono units has a bit of self noise that can be heard if an LP isn't playing. This particular phono unit has a little more gain than average, so this isn't that unusual.
I'm going to continue with 4x for awhile, maybe a very long while...
Thanks to
@adias &
@leafy7382 for prodding me to give 4x another try.
