Integrated Amplifier for Sonus Faber Guarneri Evolution

I just purchased second hand SF Guarneri Evo's. They are the nicest looking stand mounted speakers I've seen.

I'm currently driving them with a NAD M33 and I think it is not the right match for them. There is no dynamics and they sound thin to me. I think these speaker have a lot more potential.The speakers are 4 ohms with a sensitivity of 86db. I listen to jazz, blues, instrumental and classical mostly.

My room is about 13 by 17 ft.. I have a Bluesound streamer and a Denafrips Ares II DAC.

I'm open to suggestions or recommendations for a nice Integrated Amp. I have a $10-12K budget. I rather buy it used, since I think I get a better value. I live in the Los Angeles area.





Forgot to mention the place that’s selling the Vitus I recommended above (TMR) allows for an in-home trial period.  Not sure of the terms, but especially at these prices it’s very nice to have the opportunity to hear it in your system and have an out if for some reason it doesn’t work for you. Just FYI.

I purchased the Vitus Mi100 based on the suggestion from SOIX. I researched it and seem the right option, actually and excellent option. I'm getting it next Wednesday or Thursday. I'll make comments. 

Thank you so much to everybody for all the comments. I learned a lot.
