VTL2.5 or PrimaLuna2: wich is better as preamp?

Thanks for the feedback so far!

I purchased a used VTL 2.5. to pair with Rega Maia3 amp.

I gained a lot with a more revealing soundstage and better timbres overall. Now I can hear much more music at "nigh mode" low volume...

However it seems that I cannot use all headroom available (I cannot crank to much the volume, never passed 12:00!!).

Maybe because Rega Naos speakers are very efficient?
Maybe there is a better synergy to both Naos speakers and VTL2.5, what do you suggest?

thanks!

Good choice with VTL preamp.
Your 92db speakers will feel quite comfortable with 30wpc. amps.
Is the replacement of Rega amp an option? If so...I would start there.
Keep in mind that it's a system synergy that matters. Choose carefully.

Thanks Mrjstark.

Yes, of course the replacement of Rega amp is an option.
However it must be good and cost efective and a real improvement.

And I want to keep options open for the future. Like bi-amping to get better bass control and driver efficiency.

I am keeping an eye on some Class D projects (wonderful control of the Naos with nuforce, for example).

But I am not a techy so not really know how to evaluate pre and power match ... at least before I listen, of course.

I just wonder if I can explore more of the VTL with another amp.

Feel free to leave your sugestions.

Hello, I just replaced the valves.
I was adviced to install the recommended valves from VTL.
The sound got much tighter, much better in definition.
Still valve sound and sweet voices, but now drums can kick too...

So this means that the previous owner obviously have different tastes and looked for a different sound.

Just how sensitive is the VTL to this changes??
