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 all.

Stevecham, Krell KCT will be ideal but it is out of my price range which is less or more $2,500.

Rwwear, I have heared stories that Pass remote is not user friendly, however, the same stories also praised Pass sound as being open and dynamic.

Muralman1, the H2O Fire Preamplifier is not a balanced design.

Please more opinions on Mark Levinson 380s, Pass Labs X1 or Ayre K-5xe!

Haroon, have you looked inside the Fire? If not, how can you say it is not a balanced design?
I have owned the Ayre K-1xe with my krell amps. I have also heard the Ayre K-5xe with krell amps at thiel. Both work very well with the krell amps.
Muralman1, this is off topic discussion. However, I went to the website of H2O Fire Preamplifier and checked the specifications before I posted the comments. The preamplifier doesn't have XLR inputs/outputs. I believe you intend to say that some preamplifiers do have XLR inputs/outputs but they do not have balanced circuitry and vice versa.

Please more opinions on Mark Levinson 380s, Pass Labs X1 or Ayre K-5xe!
