SS balanced preamplifier for Krell FPB 400cx


Currently my system is,

Sony DVD player/Laptop Music Server
Mark Levinson 360S DAC
Balanced Audio Technology VK-3iX Preamplifier
Krell FPB 400cx Amplifier
Focal JmLabs Electra 926 Speakers
Balanced Audioquest cables

I am extremely happy except sometimes I feel that some speed and resolution is lacking. Because I have listened to other components performed flawlessly at other places, I believe tube preamplifier is the limiting factor. I have decided to experiment with balanced solid state preamplifier and currently considering used Mark Levinson 380s, Pass Labs X1 or Ayre K-5xe.

Kindly write your opinions.

Thanks Rwwear!

Any opinions on Mark Levinson 380s, Pass Labs X1 or Ayre K-5xe with Krell FPB series amplifiers?

Regards
I have tried the Pass XO and it is excellent. The low level detail was better than the PCA but it could be a little bright. The remote and ergonomics needed improving for the Pass also.
