Looking for nearfield passive speakers that are warm and rich

You could try a passive preamp/volume control, Cardas interconnect/ speaker cable etc.

@jackd  I am getting an offer of a demo pair of Folia Jubilee for $1200 all in.  Tempting.

@noromance  I like the idea of just swapping the 6550 to tungsol to see what happens. The prior owner actually preferred tungsol and when I had the unit checked by ARC they took the Tungsol, pocketed it and then put in Sovtek.

How about something like the Sonus Faber Concerto's, Concertino's, Minima Amator II's, Cremona Auditor/ Auditor M's or some Vienna Acoustic Hyden's?

Harbeth P3ESR seems like a popular warm option.

The P3ESR is warmer than your SCM7 and outstanding for nearfield, jazz, and vocals that you mentioned. They are also the same size as the SCM7 and can be a direct replacement on your desk. However it has the same amount of bass, and for more you would need to go larger. What are your size constraints?

Would you consider a subwoofer? I have excellent results with my P3ESR-XD and REL subwoofer in a nearfield desktop system. You could start by trying a subwoofer with your SCM7s.

@mspot currently using dual PSA V1800 18 inch subs with the ATCs ;)

I think my issue with the ATCs is just the treble bite which i want to do tone down.. and maybe a bit more midrange fullness.

Ya I am interested in the p3esr vs JMR folia.
