Coda 07X vs Backert Rhumba extreme vs VAC renaissance V


Hi all, I am making a major changes in my system. I have always been using SS and am changing from SS integrated to separates. I have always loved class A and now want to get flavor of tubes (for their 3D like holographic sound). My amp (which will arrive soon) is Audia Flight strumento no.4 mk2. The input impedance for this amp is rated as 7,5 kOhm. 
Based on some research, I have narrowed down to above three pre-amps and would like to keep budget < 6K (Ok being used). My inclination is to go for Backert or VAC, but have heard people talking about Coda 07x, being a SS, is very tube like. Has anybody compared or listened to these ?. I know there is always a flavor of sound being subjective and it is best to audition first. But I have busy schedule and for the first time, want to make purchase without auditioning.

Excellent choice.  The VAC will have no issue with you amp’s impedance.  I have the Renaissance V and it is an excellent piece driving my Ayre VX5.  You can do some substituting of the 6922 tubes and enjoy different subtle changes, but VAC has voiced it well with the factory supplied new production tubes.
