Musical Fidelity's x10-v3 tube output buffer?

It's been only a few days so far. I am not sure it is all burned-in for fair audiotion. Anyhow, X10-v3 tube buffer does 'volumizing' the presentation or smooth out the texture and the details. Music is a bit slower than before. It helps certain types of recordings but they are small percentage among my CD collection. It's not my taste, at least with my current system set-up. I'll return it, if x10-v3 does not improve over the next 2 weeks. I'll post in 3 weeks.

If you hear music to relax, if might help. But, there are good CD players, cost at or lower than $400, that can do similar stuff very well (used Rega, NAD, etc.)

Note: I have not used X-PSU. My CD player is one of the top of the line Sony.

I agree with Quadophile.
It was nothing but a noise generator.
X10-V3 tube even failed to improve $100 Sony CD Player as you and I guessed.

I returned mine.
