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.

Hi, 

I have heard the Strumento through the VAC specifically the Signature MK IIa. Holographic soundstage and excellent pretty much all around. DCed

I decided to go with VAC. I will be getting VAC Renaissance MK V and see how it sounds. Thanks everyone for input.

Its good you’re thinking about impedance issues. That 7.5k input impedance is very low and likely to present an issue with many tube based pres. If the pre's output is capacitor coupled, you’ll likely need capacitors of at least 10uF. https://www.v-cap.com/coupling-capacitor-calculator.php

Yes, I was a bit concerned about low input impedance of my amp, but again with 150-300 ohm output impedance of vac, the ratio of 25-50:1 was right were it needs to be and hence pulled the trigger.
