Integrated amp for 2500-3000

I own the Musical Fidelity M-6Si integrated amp and am VERY surprised it sounds this good.  The M6si offers excellent performance, facilities, and power.  The M6si is configured as 2 independent monobloc power amps with a separate preamp. It is, in fact, a preamp with 2 monobloc power amps that just happen to share the same casework.

The M6si has 220wpc. It has very low distortion, outstanding noise ratio and extremely flat frequency response.   
 

How about a preowned NAIM Supernait3 integrated amp?

See MFG link

“In the six years since the last NAIT integrated amplifiers were released, Naim's research and development team has worked on a range of amplifier improvements. The results is upgraded power amplifier sections for SUPERNAIT 3, delivering greater pace and intimacy to their musical delivery – whether it's driving a pair of loudspeakers or your favorite pair of headphones”.  
 

FYI: the Hegel H190 has been replaced by the Hegel H190v. The H190v is an updated version of the H190, offering improved features and performance. It includes enhancements such as a high-end DAC, a phono stage, a top-tier headphone output, and various streaming options. The H190v is priced at $4,200.

Maybe a preowned Hegel amp?  

@alnubis, Your received several suggestions for many integrated amplifiers.  Is it possible for you to audition some of these amp suggestions?  Based on my experience, the only way for you to know what amp you like is to listen to it.  

Is this possible?  Please keep us posted on what you decide.  thanks..
